Cherish the important achievements of China’s anti-epidemic struggle

Tong zhaohui

　　Over the past three years, China’s anti-epidemic and epidemic prevention process has been extremely extraordinary. Facing the severe and complicated situation, the CPC Central Committee with the Supreme Leader as the core has always adhered to the people first and life first, United and led the whole party and people of all ethnic groups to fight the epidemic with one heart, with a strong historical responsibility and strong strategic determination, optimized and adjusted the prevention and control policies and measures according to the situation, effectively coordinated the prevention and control of the epidemic and economic and social development, withstood the impact of multiple rounds of virus mutation, minimized the serious illness rate and death rate, effectively protected people’s life safety and health, and created a populous country to successfully get out of the epidemic in the history of human civilization.

　　The remarkable advantages of the Communist Party of China (CPC)’s leadership and Socialism with Chinese characteristics’s system are the fundamental guarantee for China to win the fight against the epidemic.In the face of the menacing epidemic, General Secretary of the Supreme Leader has always personally commanded and deployed, explicitly demanding that people’s life safety and physical health be put first, and repeatedly stressing that epidemic prevention and control should be the most important task at present. "In order to protect people’s lives, we can do anything!" Over the past three years, the General Secretary has presided over the The Politburo Standing Committee (PSC) Conference and the Politburo meeting of the Chinese Communist Party for many times, and made important instructions for many times, which pointed out the way forward and provided fundamental follow-up for coordinating epidemic prevention and control and economic and social development, and provided fundamental political guarantee for calmly coping with various major risks and challenges. Under the strong leadership of the CPC Central Committee with the Supreme Leader as the core, the whole party, the whole army and the people of all ethnic groups throughout the country made concerted efforts to overcome difficulties and successfully avoided the widespread spread of virus strains with strong pathogenicity and high mortality. Since November 2022, we have achieved a smooth transition in epidemic prevention and control in a relatively short period of time, with more than 200 million people being treated and nearly 800,000 critically ill patients being effectively treated. COVID-19’s mortality rate has remained at the lowest level in the world, and it has achieved a major decisive victory in epidemic prevention and control.

　　Practice has proved that the Communist Party of China (CPC)’s incomparable strong leadership is the most reliable backbone of the people of China when the storm strikes. Socialism with Chinese characteristics system has extraordinary organization and mobilization ability, overall coordination ability and implementation ability, and can give full play to the unique advantages of concentrating on doing great things, difficult things and urgent things. As long as we unite as a "hard piece of steel" under the banner of the Party and give full play to the advantages of the socialist system, the great ship China will surely be able to brave the storm, break the waves and forge ahead.

　　The majority of medical staff are United in their efforts and forget their lives, which is the backbone of China’s anti-epidemic struggle.The anti-epidemic course of more than three years is a panoramic record of the vast number of medical staff who are dressed in white as a armor, go retrograde, risk their lives and forget their lives, and fail to fulfill their mission. When the epidemic situation in Wuhan was at its worst, the Central Committee of the Communist Party of China gave the order, all directions rushed to help, 42,600 soldiers in white went out in reverse, and many intensive care professionals went out to fight as fast as they could, and more than 8 million pieces of protective clothing and more than 70,000 sets of medical treatment equipment were urgently dispatched … The epidemic situation was the order, and white clothes were the uniforms. With sincerity to the motherland and people and respect for life, the vast number of medical staff fought against time and continuously, and built a steel Great Wall to stop the virus with flesh and blood, saving one life after another and interpreting the doctors’ kindness and great love. For more than three years, the majority of medical staff have always adhered to the forefront of the anti-epidemic struggle, guarding their lives with professionalism, taking on the mission with great love, and working with high intensity and overload for a long time. "People first, life first", "Protecting people’s life safety and health can be done at all costs" … These loud China voices reverberate in the hearts of every white soldier and warm the hearts of every Chinese.

　　Scientific prevention and control, rapid response and flexible response are the magic weapons for China’s anti-epidemic struggle.After the outbreak of the epidemic, the CPC Central Committee with the Supreme Leader as the core attached great importance to it, made rapid arrangements, formulated strategies and strategies for epidemic prevention and control in time, and led the people of the whole country to launch a people’s war, an overall war and a blocking war for epidemic prevention and control, which effectively changed the dangerous process of virus transmission. After entering the stage of epidemic normalization prevention and control, the CPC Central Committee scientifically judged and determined the general strategy of "external defense input, internal defense rebound" and the general policy of "dynamic clearing", effectively handled more than 100 cluster epidemics, and won valuable time for the development and application of vaccines and drugs and the preparation of medical resources. After the epidemic prevention and control entered a new stage, the prevention and control measures were continuously optimized and adjusted around "protecting health and preventing severe diseases", and a smooth transition of epidemic prevention and control was realized in a short time. Practice has proved that at every stage of epidemic prevention and control, we have made a correct choice based on rationality, science and responsibility. Our prevention and control strategies at different stages have achieved remarkable results.

　　The practice of the anti-epidemic struggle has fully demonstrated the power of scientific decision-making. Medical experts who fought in the front line of anti-epidemic put forward many important suggestions from a professional point of view, which were adopted by the Central Steering Group and the National Health and Wellness Commission, providing valuable experience for the prevention and control of epidemic situation nationwide. In view of the false negative of nucleic acid detection in the early stage of the epidemic, the suggestion of "clinical diagnosis" was put forward, which was adopted by the central guidance group, so that a large number of patients were treated in time and realized "all due and all due"; In view of the increasing number of early severe and critical patients, the treatment is difficult and the prognosis is poor, it is very important to put forward the principle of "moving forward and actively treating" in time for medical treatment and epidemic control; According to the clinical characteristics of patients, the early identification methods of severe and critical patients are formulated; Formulate a series of diagnosis and treatment norms and procedures, and so on. In addition, rushing to build a shelter hospital, developing vaccines through multiple technical routes, carrying out large-scale nucleic acid detection, tracing the source of big data and identifying health codes, and preventing and controlling the differences by region and classification are all respects and promotion of the scientific spirit, which have provided strong support for overcoming the epidemic.

　　Work together with other countries in the world to overcome the difficulties and show China’s role as a big country.When you are cold, you will know the pine and cypress, but when you are in trouble, you will see the truth. When the epidemic in China was at its worst, the World Health Organization sent a team of experts to China to help fight the epidemic, and many countries gave them moral and material support. When the epidemic broke out in many places around the world and some countries encountered difficulties, China overcame its own difficulties and launched the largest global emergency humanitarian action since the founding of New China, conveying the big pattern and great responsibility of a developing country, which is responsible for the life safety and health of its own people as well as the global public health. China has co-organized more than 300 technical exchange activities on epidemic prevention and control, medical treatment, etc. with more than 180 countries and regions and more than 10 international organizations, sent anti-epidemic medical experts to 34 countries, provided a large number of anti-epidemic materials to more than 150 countries and 15 international organizations, and provided more than 2.2 billion doses of COVID-19 vaccine to more than 120 countries and international organizations … China has helped save thousands of lives around the world with practical actions, and demonstrated China’s sincere desire to promote the building of a community of human destiny with practical actions.

　　The epidemic knows no borders, and human destiny is shared. In the process of fighting the epidemic, the international community has helped each other in the same boat, showing the powerful strength of the community of human destiny. Strengthening global public health governance still has a long way to go and requires the joint efforts of all countries in the world. We are willing to share anti-epidemic experience with other countries, jointly develop and produce vaccines, strengthen epidemic monitoring and information sharing, and promote the construction of a global public health governance system; With a more open and inclusive attitude, we welcome the international community to carry out scientific research and cooperation in China and make positive contributions to global public health governance; Adhere to multilateralism, oppose unilateralism and protectionism, promote the construction of an open, inclusive, inclusive, balanced and win-win global public health governance system, and make greater contributions to building a community of human destiny.

　　Be prepared for danger in times of peace, "combining peace with epidemic", and resolutely consolidate the hard-won major achievements in epidemic prevention and control.On February 16th, 2023, the General Secretary of the Supreme Leader presided over the The Politburo Standing Committee (PSC) meeting, fully affirmed the great achievements made in China’s anti-epidemic and epidemic prevention in the past three years, profoundly analyzed the current situation of epidemic prevention and control, defined the objectives and tasks of the new stage of epidemic prevention and control, and made comprehensive arrangements for all prevention and control work. We should cherish the important achievements in the anti-epidemic struggle, thoroughly sum up the anti-epidemic experience over the past three years, grasp the work of epidemic prevention and control in the new stage with a sense of responsibility that we can’t rest assured at all times, strengthen the health service system, and resolutely consolidate the hard-won major achievements in epidemic prevention and control.

　　We must conscientiously implement the decision-making and deployment of the CPC Central Committee, tighten the "four-party responsibility", focus on key links, strengthen the capacity building of epidemic monitoring and normalized early warning, improve the epidemic monitoring system and information reporting system, make timely and accurate early warning, and take necessary emergency prevention and control measures. We will do a good job in the construction of a normalized, graded and stratified medical and health system, optimize the distribution of resources, build a strong three-level medical and health service network with public medical institutions as the main body, promote the expansion and sinking of high-quality medical resources, and make graded diagnosis and treatment truly highlight the effect; Take measures to strengthen the capacity building of medical institutions such as community hospitals, so that some minor illnesses can be solved in small hospitals; Effectively solve the problem of brain drain, retain primary medical staff, strengthen security, improve the incentive mechanism, and retain and use talents well. Coordinate the promotion of scientific and technological research in the field of health, and gather all forces to improve the scientific level of life and health; Strengthen the production and supply of medical materials, consolidate and improve the overall deployment mechanism of personnel and materials, and effectively solve the shortcomings and weaknesses in grassroots frontline capabilities, medicines and equipment. Do a good job of "combining epidemic prevention with epidemic prevention". When there is no epidemic situation, prepare for a rainy day and reserve strength, provide people with more accessible and higher-level medical resources by promoting the construction of national regional medical centers, and optimize the regional distribution of high-quality medical resources; In case of public health emergencies and catastrophic accidents, the plan is put in place and quickly switched, the major epidemic treatment base is quickly started, and the emergency medical resources are stably supplied and effectively responded.

　　Looking back over the past three years, we have overcome unprecedented difficulties and challenges. The important achievements in China’s anti-epidemic struggle are hard to come by and deserve to be cherished. The great practice of the anti-epidemic struggle has fully demonstrated the remarkable advantages of the Communist Party of China (CPC)’s leadership and the Socialism with Chinese characteristics system, the great strength of the people of China and the Chinese nation, the profound heritage of Chinese civilization, and the conscious responsibility of China as a responsible big country, which has greatly enhanced the self-confidence and pride, cohesion and centripetal force of the whole party and people of all ethnic groups throughout the country, and will certainly inspire us to forge ahead bravely in the new era and new journey.

In order to speed up the innovation and development of Guangzhou’s digital economy, focus on improving digital productivity and explore the construction of a new digital economy ecology with data as the key element, the Guangzhou Municipal Government recently issued the Implementation Plan for Building a National Digital Economy Innovation and Development Experimental Zone in Guangzhou (hereinafter referred to as the "Plan"). The "Proposal" proposes that Guangzhou will take the lead in exploring new ideas, new models and new paths for the innovation and development of the digital economy, and build Guangzhou into an experimental field for the circulation of digital elements in Guangdong, Hong Kong and Macao, a source of national digital core technologies, and a new benchmark for the transformation of the global digital industry.

Goal: By 2022, Guangzhou’s software and information service industry revenue is expected to exceed 600 billion yuan.

According to the "Proposal", Guangzhou strives to build a policy and regulation system, a public service system, an industrial ecological system and a technological innovation system that are suitable for the development of digital economy through experimental exploration in about two years. The contribution rate of the digital economy to the regional GDP and the penetration rate of industrial digitalization are constantly improving. By 2022, the output value of the electronic information manufacturing industry in the city will exceed 280 billion yuan, and the income of the software and information service industry will exceed 600 billion yuan.

The docking mechanism of digital economy rules in Guangzhou, Hong Kong and Macao is basically perfect, and the innovative elements of digital economy are fully converged, smoothly flowed and deeply applied in Guangzhou, Hong Kong and Macao. New breakthroughs have been made in the efficient allocation of data elements and key technologies of digital economy. Guangzhou will be built into the core area of the National Digital Economy Innovation and Development Experimental Zone (Guangdong), and a number of innovative development experiences that can be replicated and promoted will be summarized, which will strongly support the construction of Guangdong-Hong Kong-Macao Greater Bay Area and lead the high-quality development of the national digital economy.

Key tasks: By 2022, the city has built a total of 38,900 5G base stations.

The Plan puts forward six tasks: accelerating the construction of new digital infrastructure, promoting the safe and efficient circulation of innovation elements, improving the construction of digital economy innovation system, enhancing the advantages of core industries of digital economy, accelerating the digital transformation of industries in key areas, and strengthening the supply of digital public services.

According to the Plan, Guangzhou should speed up the construction of new digital infrastructure. Building a high-speed intelligent network of all things. Build 5G SA (independent networking) in an all-round way, promote the construction of F5G (fifth generation fixed network), and explore and test 10 Gigabit access capability by using 50G PON (passive optical fiber network) technology. On the basis of taking the lead in realizing the commercialization of 5G, expand the test and construction scale of 700MHz band radio and television 5G network. By 2022, the city has built a total of 38,900 5G base stations, and built a high-reliability, low-delay and wide-coverage 5G network to continuously cover the city. Pre-emptively deploy the construction of transmission infrastructure such as the next generation Internet, and further enhance the end-to-end connectivity of IPv6 (Internet Protocol Version 6). Accelerate the construction of applied digital infrastructure in industries such as industrial internet and car networking, and promote the formation of industry public service platforms. At the same time, accelerate the upgrading of traditional infrastructure "wisdom+". We will comprehensively promote the construction of smart airports, smart waterways, smart ports and smart city rail transit, accelerate the intelligent transformation of Guangzhou Baiyun Airport’s construction, operation and management in the whole life cycle, support Nansha Port to build a fully digital, intelligent and unmanned Bay Area demonstration port, and build a national smart city rail transit benchmark demonstration.

It is worth mentioning that in terms of the circulation of innovative elements, Guangzhou should explore the establishment of a government "chief data officer" system to promote the innovation of public data application scenarios. In the fields of population management, financial services, medical and health care, education, transportation, biological safety, etc., we will co-ordinate and organize the development and utilization of public data resources, establish a list of development and utilization directories, and clarify border conditions and regulatory measures. Explore the establishment of a sandbox experimental zone for data circulation and governance, and carry out pre-research on relevant laws and regulations such as data confirmation and personal data protection. Accelerate the legislative work in the field of digital economy and establish a full-chain system of data resources.

At the same time, we will strive for national support to implement cross-border open sharing and security management of data in Guangzhou, Hong Kong and Macao, take the lead in exploring the circulation rules of data elements in Guangzhou, Hong Kong and Macao, and promote the full convergence, smooth flow and deep application of data resources in Greater Bay Area.

Technical research: concentrate on the research and innovation of general technology based on digital economy

According to the "Program", Guangzhou should strengthen key technical research in key areas. Concentrate on the research and innovation of basic general technology, cutting-edge subversive technology and asymmetric technology of digital economy. We will continue to promote the implementation of research and development plans in key areas, and strive to break through key core technologies in key areas such as integrated circuit manufacturing equipment, materials and processes, basic software and industrial software.

In the key areas, it is emphasized that Guangzhou should explore the development of new integrated circuits such as FDSOI (fully depleted silicon on insulator technology) and heterogeneous integration. Support large industrial software enterprises to break through key core technologies such as CAD (Computer Aided Design), CAE (Computer Aided Engineering) and EDA (Electronic Design Automation). At the same time, accelerate the construction of major carriers and pilot demonstrations. We will comprehensively promote the construction of the national new generation artificial intelligence innovation and development pilot zone, the national artificial intelligence innovation and application pilot zone, and the national blockchain development pilot zone, and create a source of artificial intelligence and blockchain technology innovation, a new highland for agglomeration and development, a key area for open cooperation, and an experimental field for institutional reform.

Among them, Guangzhou should focus on breaking through the design of high-end general-purpose chips in the field of integrated circuits, vigorously develop the third-generation semiconductor chips, proactively lay out millimeter-wave chips and terahertz chips, give priority to the development of characteristic process chip manufacturing, support advanced process chip manufacturing, and actively promote the manufacturing of mixed digital and analog chips. Accelerate the construction of the second phase project of "Guangdong Core" in Guangzhou, and promote the IC design, packaging and testing enterprises to become bigger and stronger. Take the lead in implementing the national action plan for ultra-high definition video industry, plan to build the display capital of the world, and provide the hardware foundation for building the national ultra-high definition video application demonstration zone and content production base. In the field of smart cars, Guangzhou will promote the research and development and industrialization of high-precision sensors, car-level chips, intelligent operating systems, intelligent terminals, intelligent computing platforms, information security, high-precision maps (positioning) and other products.

The "Proposal" proposes that Guangzhou should strengthen the supply of digital public services. Among them, the digital government should accelerate the iterative upgrade. Through trusted identity, electronic license sharing, cross-departmental and cross-regional common maintenance and verification of government service data, materials, running, time limit and links will be reduced to the maximum extent, and the government service brand of "one network for running and the whole city for running" will be built, and the urban operation management center of "Sui Zhi Guan" will be built.

In terms of building a digital base for smart cities, Guangzhou proposes to build and deploy an urban brain neural sensing network with sensitive perception, interconnection and timely decision-making. We will further promote the development of intelligent transportation, speed up the two-way communication between Internet data and urban intersection signal control systems, implement flexible adjustment of traffic control with traffic flow, build a parking information platform, and improve the service levels of parking space inquiry, map navigation and parking space reservation. Actively promote the construction of smart light poles and accelerate the transformation of existing light poles with "one pole for multiple purposes".

　　"China Space Station will surpass Mir Space Station in terms of functions, application benefits, construction technology, material replenishment and other important indicators, reaching or approaching the level of the International Space Station; We will surpass the level of the International Space Station in terms of information technology, energy technology, power technology and operational cost-effectiveness. " Academician Zhou Jianping, the chief designer of China’s manned spaceflight project, revealed at the 4th Chinese Project Summit Forum.

　　At the same time, Shanguang Chen, chairman of the forum, pointed out: "With the support of the Human Factors Engineering Section, China Space Station will definitely provide a warm space home for China astronauts and world astronauts, and make original achievements in Chinese."

　　Although human factors engineering is a strange scientific field to the public, four human factors engineering conferences have been held, each time releasing heavy signals and memorable news.

　　People are full of infinite imagination about the coming year of 2020 — — The space station era is coming, and the space year is coming!

　　Do astronauts drink their own urine in the sky?

　　Regenerative life support system is a sign of long-term residence.

　　"Urine may be a waste on the ground, but it is a resource in the sky." Wu Zhiqiang, deputy chief designer of the space station system, said a lot of advanced terms before. When he said this sentence, laymen were shocked — — Do astronauts drink their own urine in the sky?

　　The ancients said "not dirty and unclean". With the development of science and technology, it seems that the time has come to subvert our "three views".

　　Since Shenzhou 5 Yang Liwei went to heaven, China entered the era of manned space flight, supported by the first generation of life support system. Later, every time Shenzhou went to heaven, it would go to a higher level in terms of human security. By the last Shenzhou XI, Jing Haipeng and Chen Dong spent 33 days cruising in space, showing their fashionable life of drinking tea and keeping fit in space to the people of the whole country.

　　Next, China enters the space station stage. What’s the difference?

　　Astronauts will stay in the space station for up to 180 days! As in previous times, it’s no good just bringing food, drink and oxygen. Although we have supporting cargo ship support, the cost of launching once is too high, and the life support system must be upgraded — — Physical and chemical regeneration life support system came into being.

　　"Machines should serve people." This sentence that Shanguang Chen often emphasized is believed to be our common belief, but in fact, with the continuous progress of technology, human beings have become more and more dependent on and worshipped machines, and gradually forgot their original intentions.

　　There is no denying that the man who created the machine is really great, and so is the machine. For example, Chang ‘e-1 to Chang ‘e-4 are exploring the moon for Chinese now, and next year’s Mars rover will help us to find out where the imagination of many generations has been entrusted. Machines have been opening up territory for us.

　　But machines can never replace people. People are uncertain, at the same time, people are irreplaceable factors. When people face new things and complex problems in person, their emotions, communicative thinking and comprehensive decision-making ability are beyond the reach of machines, which is the greatest driving force for science.

　　The summit forum on human factors engineering has been held for four years in a row. In four different cities, a large number of old academicians, old scientists, generals, lieutenant generals, chief engineers, deputy chief engineers and male and female astronauts are gathered every time. Recently, Wang Jian and Mao Ming, new academicians under great fame, have attended many meetings.

　　Why do so many famous scientists and designers of big countries attach so much importance to human factors engineering?

　　Perhaps, as China Space Station opens its doors to astronauts and scientists all over the world, human factors engineering will also be unveiled and truly understood by the public. The original research results produced by space research will serve our lives more and more.

　　With the construction of the space station, how to run the materialized regenerative life support system for long-term space flight reliably and efficiently has become the best example to explain human factors engineering.

　　Regenerative life support is a key sign system for astronauts from short-term flight to long-term in-orbit stay.

　　This environmental control and life support system not only collects and transforms people’s sweat and urine in the system, but also aims at establishing people’s living environment to ensure people to work efficiently and comfortably. In other words, the creative design practice of this system is all around people, serving people to eat, drink, sleep and work in a closed spacecraft.

　　"Regenerative life insurance technology is very complicated and is called a worldwide problem. It can be seen from the development process in the United States and Russia that the technology is very difficult and the investment is very large. " Wu Zhiqiang introduced that the development cost of a water treatment system on the US space station was 200 million US dollars. The International Space Station has been built for more than 10 years, and the regenerative life support system really only took five or six years.

　　Why are the United States and Russia so willing to invest money in this system?

　　Because according to their calculations, it costs 40,000-50,000 dollars to transport 1 kg of material to the orbit of the International Space Station, and 1 g of water is basically equivalent to the value of gold. "Of course, this is just water, and it also needs containers for water. Together, the economic cost is even greater." However, people generally need more than two kilograms of water a day, which is enough for three to six astronauts to spend six months to more than one year. It can be said that they are constantly burning money.

　　The International Space Station has spent more than 100 billion dollars. It is a challenge for China to make the design and management of the space station better and realize the pursuit of science and technology at less cost. Only by doing this can we be a sustainable development way.

　　This is the task of Wu Zhiqiang. Chinese has always had a big brain.

　　When astronauts are studied as the core of system engineering, they become very close to ordinary people. Everyone excretes 1.6 kilograms of urine and 1.7 kilograms of sweat a day, and there is water in the stool. Recycling water is the foundation. In addition, water contains oxygen, which can also be obtained by water electrolysis. In addition, the amount of carbon dioxide produced by people in breathing is 1 kg per day. These wastes should be returned to their respective places, recycled in different treatment systems, and finally converted into available resources in the space capsule. In the future, the cargo spacecraft can carry a basic amount, and the cost is greatly reduced.

　　"Reclaimed water, in a sense, is a kind of water produced in orbit. It is extracted from waste. In order to ensure people’s life and health, it must strictly meet medical requirements. " Popular science in Wu Zhiqiang has given the public a fact that if we want to travel around space, we also need to reuse the urine of the converted cabin personnel.

　　It must be said that when human beings look at the vast space, they deeply feel that it is extremely vast and has no boundaries. When human beings look at themselves, simply eating, drinking and sleeping is actually an extremely precise and borderless field. However, the study of ourselves determines how far we can go if we leave the land under our feet.

　　"This system has the most manned characteristics, and it is also an important symbol to distinguish manned spacecraft from unmanned spacecraft." Wu Zhiqiang’s task is ordinary in words, but it is a multi-system interdisciplinary subject in practice.

　　It can be seen that the parents of this body are naturally enjoying their own bodies, but they don’t realize that this is the greatest machine and there is endless room for exploration.

　　This system, which was previously hidden behind the spacecraft, is coming into people’s field of vision when astronauts are about to stay in space for a long time and are planning to go to the moon and Mars.

　　However, what if such precious recycling equipment breaks down in case it is used? This involves a typical human factor problem — — On-orbit maintenance of space equipment.

　　Even maintenance is also human.

　　The life of the space station is not only built, but also repaired.

　　"After the completion of the China Space Station, we will use the operation of astronauts and the cooperation of mechanical arms to transfer the solar wing to this position to improve the working efficiency of solar wing batteries. This is a very complicated on-orbit operation. If China astronauts do this, I think we will reach the same level of extravehicular operation as the International Space Station. " Zhou Jianping pointed out the design of China Space Station and explained it to everyone.

　　In the weightless environment, astronauts leave the cabin, transfer and repair equipment. The scene of astronauts working in harsh space environment in American movies is vivid. Many fans expect China to enter the era of space station, just to see that Chinese can do such a difficult job. The scene described by Zhou Jianping is not only difficult, but also proves the strength and ability of the China astronauts, which is exciting to think about.

　　Zhou Jianping used the space station as an example. At that time, the design life of the Soviet Union’s Mir space station was only five years. Because of the participation of some people, the Mir space station continued until 1999. Because the Russian operation and maintenance cost was unbearable, it was derailed. Similarly, there is no active participation in the current International Space Station, and it is impossible to maintain this state.

　　It seems that the life of the space capsule is not only made, but also repaired.

　　Zhou Jianping reveals the secret — —

　　This time, our telescope will also be in the earth’s orbit, with a magnificent name, called "Sky Survey". Compared with Hubble telescope, the field of view of the survey telescope is more than 300 times larger, but the resolution is comparable. It can fly in common orbit with China Space Station. When the space station needs to replenish it, the astronauts need to repair it, or the equipment needs to be upgraded, it can dock on the space station, and the astronauts will leave after the necessary operations, and then continue to fly in common orbit.

　　In the past, if satellites were launched out of control, they would lose hundreds of millions or even billions, and they would also become space junk suspended in orbit. But in the future, there will be onboard engineers in the spacecraft who can capture these satellites for maintenance. There are also some satellites that have expired, and we can also replace them for maintenance to increase their life.

　　As we all know, it is a breeze for us to twist a screwdriver on the ground, not to mention the load engineer and the astronaut from the Air Force. However, under the threat of extravehicular cosmic rays and flying rocks, astronauts must wear spacesuits as hard and heavy as a small spacecraft, and clumsy gloves make it very difficult to hold things. Therefore, the maintenance in the sky is mostly modular and integrated.

　　Just like children putting together Lego, even if it is a problem of a line or a screw, a whole module should be replaced to ensure safety and efficiency.

　　Shanguang Chen said that the on-orbit operation of the space station will reach more than 10 years, and there are many equipments including spacesuits and regenerative life support systems, which can greatly prolong the on-orbit service life and reduce the transportation cost through maintenance and parts replacement. How to ensure the quality of maintenance and improve the efficiency of maintenance should fully consider human capacity, space constraints, tool constraints and other human factors.

　　In just a few words, everyone has realized the arduous task of astronauts and load engineers in the Heavenly Palace in the future, not only to bear the test of weightlessness on the body, but also to do scientific experiments; It is necessary to observe both outer space and the earth from high altitude; It is necessary to go to the cargo ship to carry goods, to repair and overhaul the space station outside the cabin, and to launch micro-satellites to repair the survey telescope that is docked in parallel.

　　After Zhai Zhigang leaves the cabin and waves the national flag, future China astronauts will walk out of the cabin door more and more to work hard for our aircraft!

　　Half a year ago, NASA announced an Artemis project, that is, the United States won the moon again in 2024, and female astronauts will complete the moon landing. People invariably focus their eyes on Wang Yaping, the heroine of China.

　　When Shenzhou-10 was flying, as a space teacher, she gave a popular science class to primary and middle school students in the narrow cabin of Tiangong-1. The opening rate of the video at that time reached 1 billion times. If China can’t land on the moon immediately, it is certain that there will be female astronauts who will stay in the Tiangong for a long time in the near future and conduct scientific experiments in the core cabin and experimental cabin.

　　Wang Yaping’s appearance embodies the beauty of China’s classical beauties and the heroic posture of female soldiers, and her figure is tall and slim. People can’t help feeling pity for jade: how can such a slender woman carry heavy maintenance tasks?

　　This requires ergonomics to design auxiliary equipment that is more suitable for human body to work efficiently.

　　According to reports, the living environment of astronauts has been greatly improved. It can be said that from the past one room and one living room to three rooms and one living room, its livability is better and the extravehicular clothing has been greatly improved.

　　The more perfect the design of human factors, the less uncomfortable people feel, and the closer it will be to the day when ordinary Chinese will go into space.

　　Facing the unknown

　　Human factor evaluation surfaced.

　　Aerospace is a complex giant system, among which, what worries scientists most is how the people inside will survive and how to face the sinister and uncomfortable living environment when the spacecraft leaves the earth, our familiar home. In other words, how can we ensure that astronauts are "born after death" and work pleasantly and efficiently?

　　Human factors engineering studies more about death. This is a subject based on failure, disaster and lessons.

　　"The Boeing plane in Ethiopia went down vertically, reaching 20 meters underground." Academician Liu Daxiang watched the video of Boeing 737MAX’s last out-of-control state some time ago, which made him "particularly uncomfortable". This type of aircraft crashed twice in the four months from the end of last year to the beginning of this year, killing 346 people. At first, Boeing put the blame on people, saying that the driver’s operation was wrong, but "we didn’t analyze this problem, so China was the first to make a decision to stop flying". It was later proved that the pilot of this plane staged a man-machine war in the last 12 minutes. It is said that a system repeatedly forced the nose down, and the pilot repeatedly pulled the nose up again, but in the end, under the arrogant instructions of the machine, the driver could do nothing, causing human tragedy.

　　"Now all fields are completely commanded by machines, which is risky." The famous aero-engine expert in China said that Boeing 737MAX didn’t carry out enough flight test after replacing the engine, and didn’t make a comprehensive evaluation including human factors, and the result was painful.

　　Shanguang Chen believes that the Boeing accident has once again caused the industry to think deeply about the allocation of human-machine functions, and the main reason is that it does not pay attention to human factors evaluation. In fact, many accidents in the aerospace field can be attributed to human error or insufficient error-proof design of machines.

　　"Eliminating operational mistakes is my lifelong goal." Lieutenant General Hu Shixiang, who sent China’s first artificial satellite "Dongfanghong-1" into space in 1970, said this. He participated in organizing more than 100 launch tests of satellites and rockets.

　　What he remembers vividly is the launch of a communication satellite in 1982. After several simulated flights, the data showed that the rocket was short-circuited after 17 seconds of flight.

　　"Check. The socket was opened to see how the welding point was, and it was turned upside down one day and one night, and no problem was found. " Everyone can’t go anywhere, they are all waiting, and he feels stressed. Finally, it was found that there was a solder particle rolling around in a socket. Going back, it was a female inspector in Shanghai who was pregnant, "in a bad mood and missed the inspection."

　　Today, when it comes to aerospace, it is foolproof, and it is all from victory to victory. In fact, in Hu Shixiang’s memory, there was a bleak time. At that time, China had just started to help foreign countries to launch commercial satellites, and failed because of the plug problem and careless problem. "When Zhu Rongji served as deputy prime minister, he visited our base and asked, Commander Hu, can you hit three satellites and drop the next one? You go up and down now, and our hearts can’t stand it. "

　　"Plugs and sockets are often a simple problem, but the result of simple problems is very heavy. It can be said that a screw links the aerospace industry and a small button maintains national dignity. " Hu Shixiang appealed to the human factors experts who attended the meeting, and asked whether the human factors experts could give a measure and a method to reduce human errors and ensure success.

　　Shanguang Chen pointed out: Eliminating human errors and ensuring safety has always been the goal pursued by commanders and engineers at all levels engaged in complex systems and engineering projects, and human factors engineering provides theoretical guidance and design methods for this. These systems are designed by people, and they are bound to be branded by people. The system must be evaluated by relatively independent human factors, and the system that fails this evaluation shall not pass the final acceptance. Manned space flight is establishing this management and technical system.

　　The discipline idea of human factors engineering is to embody the design idea of people-centered, make the machine adapt to people’s needs, and the discipline goal makes the whole system realize safety, high efficiency and high performance. Typical characteristics are system engineering thought, design-oriented and multidisciplinary integration. It can be said that human factors engineering is a people-oriented system engineering.

　　Laozi said: goodness is like water, and water conservancy does not dispute everything. Shanguang Chen borrowed this concept many times and pointed out: people are like water, and if you are tall, I will retreat and not drown your grace; If you are low, I will come to make up for your shortcomings. More and more big countries have introduced human factors engineering into their own top-level design.

　　Bridgehead towards deep space

　　When will cars come and go on the moon?

　　Just like Go, when you take a step, you must design the next three to five steps.

　　When people are cheering and screaming for the 2020 space year, China’s manned space flight has started the deep layout of flying to the moon.

　　Why do you choose the moon for deep space? Shanguang Chen said that manned space flight has three main goals: first, exploring the unknown; The second is to develop and utilize space resources; The third is to expand the living space and find a new home. The moon is "the bridgehead for us to go deep into space".

　　In many science fiction novels, water ice, helium 3, important minerals and other resources on the moon are mined by clones and robots and transported back to the earth to serve mankind. So, what will the moon look like? Will there really be cars coming and going like Shanguang Chen said?

　　He believes that our future moon city will be implemented in stages: outpost, semi-permanent base, and then permanent moon home.

　　The moon home is mainly underground buildings, which can use moon soil and moon rock for heat preservation, heat insulation and radiation protection. Using 3D printing, the lunar dust and excavated lunar soil are printed into building materials. Choose a place where underground space is easy to drill and dig, and take Moon Rock as the base radiation bunker.

　　Shanguang Chen’s description is full of wonderful imagination. Perhaps, with the strong support of engineering and other disciplines, it will be close at hand when we have a super-large thrust rocket?

　　But he changed the subject and talked about a "successful failure."

　　At that time, Apollo 13, which flew to the moon, only flew for 55 hours and 46 minutes, and the agitation of the oxygen tank led to the serious explosion of the spacecraft service module. The spacecraft began to lose power, heat and, more importantly, the astronauts lost breathable oxygen.

　　"However, the astronauts used their quick wits to use the Aquarius lunar module as a lifeboat, and finally got rid of the gravity of the moon and returned to Earth safely. This is a successful case of relying on people’s wisdom and exerting people’s role, so it is a successful failure. " Shanguang Chen hopes to use this example to tell everyone that if we want to March to the moon, we must have more advanced human factors engineering concepts and designs.

　　Because human factors engineering is a kind of efficacy discipline based on failure and death.

　　What is a good designer? "Under danger, the system has the ability to play a human role and restore security." Shanguang Chen pointed out that, inspired by the experience of Apollo 13, our lunar module will directly carry the escape module in the future, which will increase the hope of astronauts’ survival.

　　The characteristic of aerospace is that many escape devices have been designed before. For example, when a rocket is launched, there is an escape tower in the atmosphere, and if something happens, it can parachute back to the ground. Therefore, whether you enter the Tiangong capsule or go to the moon in the future, you should put safety and efficiency first.

　　"Through the construction and development of the moon home, mankind will go to deep space, move to Mars, get out of the solar system, inherit the spark and spread human civilization in the vast universe!" Shanguang Chen set his sights on the future.

　　Perhaps looking back in a few years, 2020 is a very important time node for China’s space flight. Such a grand plan is to start from the core module of the space station — — Tianhe, take the first step.

Social networking has brought people closer together. In recent years, with the development of Internet platform economy, people can even be directly "stitched" together like cloth.During the epidemic, when it was impossible to eat in the restaurant, the takeaway staff sewed up a kilometer between the home and the restaurant; When there is no offline activity, the live broadcast sews up the lack of entertainment. In such a society, what marks are left by people as stitched fabrics?

Dong Chenyu, a lecturer at School of Journalism, Renmin University of China, will take us to discuss:

Zhou Feizhou: Does everyone have to be a "social person" unless he is a "social cow" or "social fear"?

Professor and Director of Sociology Department of Peking University.

Modern people have their own cognitive way of "society": being able to communicate with the outside world without fear of being laughed at is a "social cow", and being afraid of communicating with the outside world without being concerned is called "social fear". However, no matter what kind of personality, such a division separates itself from society and forms opposition.

As one of them, obviously we can’t be separated from society, but we are cutting with society all the time.How to truly "enter the society"? How can we be more open to ourselves and others?

Professor Zhou Feizhou, director of the Department of Sociology of Peking University, will share with us:

But don’t be swallowed up by the mud and lose the ability to look out. Raise your head and look farther away, where there may be another possibility of saying "no"

Professor Wang Min ‘an from Tsinghua University College of Humanities will take us to discuss:

　　Xinhua News Agency, Jakarta, November 8-A 7.2-magnitude earthquake struck the waters near Maluku province, Indonesia, and no casualties or property losses have been reported.

　　According to the website of the Indonesian Meteorological, Climate and Geophysical Bureau, the earthquake occurred at 11: 52 Jakarta time (12: 52 Beijing time), and the epicenter was located in the sea area 251 kilometers northwest of Taningbar Islands County, Maluku Province, about 341 kilometers away from Ambon, the capital of Maluku Province, with a focal depth of 10 kilometers.

　　Indonesia’s Meteorological, Climate and Geophysical Bureau recorded strong earthquakes on islands near the epicenter. The bureau did not issue a tsunami warning for this earthquake, but warned that there may be aftershocks near the epicenter.

　　According to the news released by the Earthquake Information Network of the US Geological Survey, the magnitude of this earthquake is 6.9.

　　Indonesia is located in the Pacific Rim seismic belt, and thousands of earthquakes occur every year. In September 2018, an earthquake of magnitude 7.4 occurred in Dongala County, Central Sulawesi Province, Indonesia. The earthquake and its tsunami caused more than 2,000 deaths.

　　Cctv newsOn the afternoon of September 29th, the Ministry of National Defense held a regular press conference, and Senior Colonel Tan Kefei, deputy director of the Information Bureau of the Ministry of National Defense and spokesman of the Ministry of National Defense, answered questions.

　　Reporter:It is reported that Taiwan’s defense department recently submitted to the legislature the Report on the Military Power of the Chinese Communist Party in 2022, saying that the mainland "seriously threatened Taiwan’s defense security and peace and stability in the Taiwan Strait" and used the exercise simulation to prevent foreign troops from providing assistance to Taiwan Province in case of war. In addition, according to Taiwan media reports, Taiwan’s "defense budget" in 2023 will increase substantially, with an increase of 13.9%. What’s your comment on this?

　　Tan Kefei:It is extremely irresponsible for the relevant report to deliberately exaggerate the so-called "mainland military threat", confuse the right and wrong, and raise the tension between the two sides of the strait. Taiwan Province is a part of China. The "Taiwan independence" separatist forces and their activities have always been the biggest obstacle to the reunification of the motherland and the serious hidden danger of national rejuvenation. The PLA’s military training activities in the sea and airspace near Taiwan, China Island are just and necessary responses to the persistent provocations of the "Taiwan independence" separatist forces, and are just actions to safeguard national sovereignty and territorial integrity. No one has the right to make irresponsible remarks.

　　The Democratic Progressive Party authorities distorted and denied the "1992 Consensus" and linked external forces to constantly seek "independence" provocation, which is the root cause of the current tense and turbulent situation in the Taiwan Strait. "if you don’t celebrate your father, Lu is not finished." If Taiwan independence is not eradicated, there will be no peace in the Taiwan Strait. The China People’s Liberation Army is determined to safeguard national sovereignty and territorial integrity. As long as the Democratic Progressive Party authorities and the "Taiwan independence" separatist forces "seek independence by force", our military countermeasures will never stop.

CCTV News:On the 15th of this month, the two sides agreed that North Korea would send the Sanchiyuan Orchestra composed of more than 140 artists to South Korea to perform during the Winter Olympics. As an advance team, the Korean artists’ performance delegation first arrived in South Korea. From the 21st to the 22nd, DPRK personnel visited the art centers and stadiums in Gangneung and Seoul, South Korea, respectively, and their inspection will be the basis for choosing the performance place of the art troupe. Among the delegation, the most concerned is their head, Xuan Songyue.

　Xuan Songyue (video screenshot)

On the afternoon of January 22, local time, it was snowing lightly, and the delegation came out from the Korean National Theatre. Xuan Songyue, head of the delegation, boarded the bus and left with his trademark faint smile.

On the same day, the 7-member delegation visited Seoul Silkworm City Student Gymnasium, National Theater and Award-winning Gymnasium to learn more about the environment, equipment and the size of the audience.

On the 21st, after the delegation arrived in South Korea, it first inspected the performance place there, and stopped at Gangneung Art Center for about two and a half hours to carefully check the facilities and equipment such as audio equipment, dressing room and dressing room.

Tight security, South Korea dispatched a large number of police forces.

South Korean media reported that, as a North Korean who "set foot on South Korean soil" for the first time since South Korean President Moon Jae in took office, South Korea has very strict security for Hyun Sung-yueh and others, and the South Korean media even described it as "an iron bucket". As can be seen from the pictures published by the media, after the North Korean motorcade entered South Korea, South Korean police patrol cars and motorcycles followed closely. Along the inspection route and near the hotel where the delegation stayed, the police also closely guarded the defense.

South Korean media broadcast the news of the DPRK representative’s visit to South Korea.

South Korea YTN TV host:The dress of the representative of the DPRK, Xuan Songyue, attracted people’s attention. She was wearing a long dark coat, high-heeled boots, a fur scarf, a brown handbag and a ring on the ring finger of her left hand. Dark and thick hair with a diamond-encrusted hairpin looks elegant and generous.

Xuan Songyue’s visit to South Korea caused great concern.

Some Koreans are very enthusiastic about the arrival of Hyun Sung-yueh and his party. On the morning of 22nd, outside the hotel where Xuan Songyue stayed, a large number of Jiangling citizens came to watch and take photos. However, when the delegation took the high-speed train from Gangneung to Seoul that day, some South Korean conservative forces shouted slogans against their arrival outside Seoul Station.

Xuan Songyue: The national meritorious actor was active in the Korean music scene.

Xuan Songyue’s performance (data map)

At present, North Korea has not publicly reported Xuan Songyue’s personal information. According to South Korean media reports, Xuan Songyue was born in 1972 and graduated from Pyongyang Jinyuanjun Music University, known as the cradle of "artists". In the 1990s, Xuan Songyue, as a national meritorious actor, was active in the Korean music scene.

Korean media: Xuan Songyue is the head of two major orchestras in North Korea.

　According to South Korea’s YTN TV station, at present, Xuan Songyue is the head of the Sanchiyuan Orchestra, which is about to perform in South Korea. Sanchiyuan Orchestra was established in January, 2009. It mainly plays light classical music. Players will not only wear national costumes or military uniforms, but also wear western-style dresses, which is more in line with the aesthetics of the public.

In 2014, Xuan Songyue was the head of the Peony Peak Orchestra, which was the first women’s electronic orchestra initiated by North Korean leader Kim Jong-un in 2012. The performance was novel and flexible, and the members were beautifully dressed and fashionable. It was known as the "women’s day group" in North Korea.

In 2014, Xuan Songyue was already a senior colonel. In the same year, she also made a speech as a representative at the Ninth Congress of Literary and Art Workers in North Korea.

At present, North Korea has not announced whether Xuan Songyue is still the head of the Peony Peak Orchestra.

In addition to enjoying a high reputation in the art world, Xuan Songyue also has a certain position in politics. In October 2017, she became an alternate member of the Central Committee of the Labor Party, which is very rare among female artists.

At present, the hard-core SUV that is in the limelight must be WEY Tank 300. Tank 300 has just held a test drive meeting in Chongqing for urban and off-road conditions. It can be said that the product strength has become perfect, and only the final guide price and specific configuration have not been announced. In addition to Mercedes-Benz G and Land Rover, there is also a benchmark product in the field of hard-core SUV, JEEP Rubicon (hereinafter referred to as Jeep Rubicon), but the price of more than 500,000 yuan still makes many friends with limited budgets want to wear it. Compared with the tank 300, of course, the prices of the two are not in an order of magnitude, but they can compete in other aspects such as mechanical quality, face value and size. There are many potential car owners around me who have ordered tank 300. Let’s take a look at how to choose these two hard-core SUVs.

The appearance of the tank 300 is stylish and tough, and the herdsman classic can stand the test.

Tanks 300 and 300 both adopt a castle-like body shape with narrow top and wide bottom. The extended wheel eyebrows not only look wild, but also have practical significance in terms of functionality. They are not afraid of scratching in the wild road conditions, and can accommodate larger tires after later modification. Tank 300′ s hood latch is built-in, which absorbs the shortcoming of poor anti-theft caused by the external latch. The outstanding hard bumper can be equipped with Vaughan 9500-pound winch, which is more intimate. The headlights of both of them adopt retro circular design, and the tank 300 also boldly adds a horizontal daytime running light, which makes people unforgettable. Needless to say, every man can’t resist such a tough appearance, and you will also see many young ladies sitting in the driving seat on the street.

The tank 300 and its sides are square and tough, and it can be seen that the front of the tank 300 is shorter, leaving more space for the passenger compartment. The size of the front bumper protruding forward is too large, the winch is not standard/optional in the original factory, and the approach angle of the vehicle is affected, which is really unnecessary.

As for tires, the trial car of Tank 300 adopts Cooper ATT lightweight AT tires with the size of 265/65/R17, and the tires after mass production may be adjusted, while Lubicon uses the more extreme Bailuchi KM2 mud tires, which has stronger off-road performance and louder tire noise on the road. Compared with extreme climbing, I hope that the tank 300 is equipped with Bailuchi KO2 tires with better off-road and urban comprehensive performance, which will be perfect.

The rear of both cars are very square, and both adopt the way of side door opening, but the rear window needs to be opened up separately to fully open the trunk. It is worth mentioning that the rear towing hook of tank 300 is very strong by welding directly on the girder; It is a pity that the original factory is not equipped with a rear towing hook, only the installation hole is reserved, and the owner needs to install it himself.

The interior tank 300 has both luxury and technology, and herdsman has excellent practicality.

The style difference between the two cars in the interior is very obvious, and the tank 300 obviously has the luxury technology style led by Mercedes-Benz G. Two 12.3-inch Dalian screens are full of technology, and the UI design is also very modern, and more off-road parametric information can be displayed intuitively. The air outlet of turbofan engine style air conditioner is made of metal fog silver, which is very delicate. And a large number of leather and soft packages in the car are very satisfactory. This set of interior can be played quite well even if it is placed in a 400,000 yuan city SUV.

Compared with JK interior, the current JL interior is obviously improved. Although the overall design is horizontal and vertical lines, the accessible areas are all soft materials. The 7-inch central control panel is wrapped in a thick black border. If it is placed on a city SUV, it must be criticized. However, it has a three-proof pad style on the body, but it is very tonal.

Off-road configurations are the top in the industry, and herdsman is stronger.

Tank 300 and not only the exterior and interior are very interesting, but also the strong off-road configuration is the foundation of these two cars. In terms of performance parameters, both cars are very tough. approach angle and departure angle over 30 degrees are ahead of most hard-core SUVs, especially the two-door and four-door models have a ground clearance of 276mm, which can ignore many obstacles and be more tough.

Both cars are equipped with low-speed four-wheel drive and mechanical differential locks that can be actively locked at the front and rear axles. This alone can make these two cars stand out from the crowd. Tank 300 can choose part-time 4wd and TOD timely four-wheel drive according to different models, and 4H AUTO gear has been added on the basis of part-time 4wd, all of which are focused on driving to adapt to urban road conditions. It’s not over yet. Rubicon can also take the initiative to disconnect the anti-roll bar and increase the suspension stroke during extreme climbing to keep the wheels from leaving the ground as much as possible. It can also be seen from this point that Rubicon is more suitable for extreme off-road.

Power system equivalence

Tank 300 is equipped with a 2.0T engine, with a maximum power of 227 HP and a peak torque of 387 Nm. It is equipped with ZF 8-speed automatic manual transmission. JEEP also uses a 2.0T engine with a higher maximum power of 266 HP and a peak torque of 400 Nm. It also uses an 8-speed automatic manual transmission.

It is worth mentioning that tank 300 can be filled with No.92 fuel, but only No.95 fuel. If you have the need to go to no man’s land, obviously the tank 300 doesn’t pick oil. Both original fuel tanks are around 80L, and the tank 300 also reserves the installation position of 40L auxiliary fuel tank, which is worthy of praise.

summary

Through the above comparison, we can see that the overall mechanical quality is more inclined to extreme off-road. If you often need to climb big stones and have sufficient budget, Rubicon must be the best choice. The mechanical quality of Tank 300 is also at the top level in hard-core off-road vehicles, and the more luxurious interior is definitely more popular with the hostess at home.

At present, the pre-sale price of the off-road version of Tank 300 has been announced at Guangzhou Auto Show, which is 17.58-21.38 million yuan. Obviously, the price is much more affordable, which provides almost the best choice for friends who like hard-core SUVs but have limited budgets. In addition, Tank 300 absorbed a lot of consumers’ opinions in the product calibration stage, and gradually improved the product with the target users, which is also difficult for imported brands. I believe it will continue to upgrade and improve after listing. Hard-core off-road vehicles also require higher product reliability, and we will continue to pay attention to the performance of tank 300 after long-term use and share it with you.
