Reproducibility of heart model development. Image source: Sasha Mendjan and others

　　Sasha Mendjan, a biologist at the Austrian Academy of Sciences, and his team used human pluripotent stem cells to cultivate a sesame-sized heart model, also known as the heart line. It can spontaneously organize and exhibit a hollow atrium without experimental support. Mendjan’s team activated all six known signal pathways involved in embryonic heart development in a specific order to induce stem cells to organize themselves.

　　As cells differentiate, they begin to form different layers-structures similar to the heart wall. After a week’s development, these organs self-organized into a 3D structure with a closed cavity, which almost reproduced the spontaneous growth trajectory of the human heart. In addition, the research team also found that the heart wall tissue can contract rhythmically and squeeze the liquid in the cavity.

　　The team also tested the response of heart organs to tissue damage. They used a cold steel bar to freeze some heart organs and killed many cells in this area. It was found that cardiac fibroblasts (a kind of cells responsible for wound healing) began to migrate to the injured area and produced protein to repair the injury. Related research was published in Cell on May 20th. This progress enabled scientists to create some of the most authentic heart organs so far, which made it possible for pharmaceutical companies to introduce more drugs into clinical trials.

This is the "Guide to the Core Literature of Social Media Research"

001 articles

Starting today, we hope to do an interesting and important thing: to sort out the core literature of social media research and try to draw an academic map for this field.

Today, the 001st paper of this project is pushed, and it is also the most cited paper in social media research: Social Website: Definition, History and Academic Map.

Boyd, D.M., & Ellison, N.B. (2007). Social Network Sites: Definition, History, and Scholarship. Journal of Computer ‐ Mediated Communication, 13 (1), 210-230. (Cited: 18601)

The question we want to answer is:

★ In this paper, how do Boyd and Ellision define social networking sites?

★ What does this definition inspire the research of social networking sites?

★ What amendments have been made to this definition in the follow-up study?

Of course, in addition to reading, if you are interested in this plan and want to "blend in" together, please read the project plan at the end of the push and contact us.

In the history of social networking sites, 2007 is worth remembering. At the end of this year, Read/WriteWeb, a well-known Internet technology review blog, decided to award the IT company of the year award to Facebook, not Google. The reason is that Facebook broke the closed system of traditional social networking sites and allowed users to obtain plug-ins from third-party companies in the site. In other words, since then, Facebook has raised its "connection" potential to a new level and become an open co-writing space.

In 2007, beyond the commercial horizon, social networking sites, as academic research objects, also ushered in its landmark works, and the key word was still "connection". If we look back in 2007, a lot of academic research on social networking sites has been accumulated in the field of humanities and social sciences, but the dialogue between them is still incomplete and needs to be integrated urgently. Therefore, the Journal of Computer Aided Communication (JCMC) published a special issue on social networking sites in 2007, and invited two scholars, danah boyd and Nicole Ellison, to write an opening article. In this opening article, two scholars discussed the definition, history and academic map of social networking sites. Among them, their definition of social networking sites has been widely cited by subsequent studies and has become a classic work in the field of social networking sites.

Here we need to briefly explain from three levels why "definition" is important for social networking sites. First, the definition represents the boundary of research. Tampering with raymond carver’s words means what we are talking about when we are talking about social networking sites. Second, the definition focuses on the research field of vision. In our definition, we distinguish social networking sites from other types of websites, and the difference is likely to be the focus of follow-up research. Third, the evolution of definition also reflects the changes of technology. Social networking sites are essentially evolving with technological updates. In the following, we will focus on the definition of social networking sites in this paper and the revision of this definition in subsequent research.

In boyd and Ellison’s review, as of 2007, social networking sites have experienced three stages of development. Sixdegree.com, established in 1997, is regarded as the starting point of social networking site. However, perhaps because it was too ahead of the times, the site announced that it would stop operating in 2001. 2003 witnessed the second stage of the development of social networking sites. Many social networking sites have mushroomed and gradually become mainstream. One of the representative websites is MySpace, which we are familiar with. Then, in the third stage, the appearance of Facebook expanded the influence of social networking sites to a global scale. So, can we sort out a common clue for these different social networking sites? What are the similarities between them, which can be summarized under the same noun?

In this paper, the two authors define social networking sites as follows:

"We define social networking sites as an Internet-based service. It allows individuals (1) to establish a public or semi-public personal homepage in a closed system; (2) establish a connection with other users and present a list of contacts on the personal homepage; And (3) viewing and shuttling through the list of connections established by oneself and others in the system. The nature and naming of these links may vary from website to website. "

Next, we will briefly interpret these three characteristics:

1. Home page

The first keyword in the definition of social networking sites is the home page. Personal homepage is the pillar of social media and the basic unit and node of social networking sites, which is one of the most important differences between social networking sites, instant messaging tools and BBS. According to boyd and Ellison, the magic of personal homepage is that it allows users to "type themselves into being". For example, users need to fill in a series of questions on their personal homepage, such as head portrait, age, residence, interests, and a series of "about me" information. This process is self-sketching. Therefore, it is not difficult to understand why the research on self-construction and impression management in social networking sites has been launched since the 1990s and has become one of the core concepts of the research.

Step 2 connect

The second keyword in the definition of social networking sites is connection. The author thinks that the uniqueness of social networking sites is not that they allow individuals to meet strangers, but that they allow users to show their social networks. This is another important difference between social networking sites and instant messaging tools. What excites researchers is that this relationship has different names in different social media-Weibo calls it "fans", Twitter calls it "followers" and Facebook calls it "friends". So, what is the relationship between people in social networking sites? More interestingly, when social networking sites use the title "friend", how will the meaning of the word "friend" change quietly?

Step 3 shuttle

The third keyword in the definition of social networking sites is traverse. This word has at least two dimensions. First, people can shuttle through their friends lists and check their friends’ messages at any time, so they can establish their own relationship network; Secondly, people can often check who their friends have. Recall that when Sixdegree.com used the metaphor of "six dimensions" in naming, he actually expressed the value of the second layer of shuttle. Similarly, one of the visions of Tinder, a dating software, is to firmly believe that people with common friends are more likely to become friends. If we continue along this line of thought, we will surely meet Caroline Haythornthwaite’s classic research on "latent ties" in 2005. Of course, from another perspective, when you are shuttling with other people’s homepages, you are also being shuttled by others. This also explains why privacy and visibility will become an important clue in the research of social networking sites.

Since its publication, the paper I introduced to you has been cited by tens of thousands of follow-up studies, most of which focus on its definition of social networking sites. However, if we stand in today’s coordinates and look back at this definition more than ten years ago, we may feel some old traces of the times. With the evolution of technology, have these three keywords changed? After all, definition can only be responsible for defining "being", but not for predicting "becoming".

In 2013, boyd and Ellison joined forces again to update the three characteristics of this definition, which are briefly described as follows for your reference:

(1) The importance of personal homepage has been greatly reduced, and social networking sites have changed from homepage-oriented socialization to behavior-oriented socialization. Even if the homepage still exists, it is no longer a static self-description, but a dynamic combination of different types of status updates.

(2) Friend list no longer only describes the circle of friends of users, but more importantly, it shows a social graph of users through algorithms.

(3) Social networking sites provide more possibilities for shuttle. Users used to only use social networking sites to establish and maintain their own relationship circle, so shuttle is closed in nature. With the continuous introduction of new functions, this closeness has been constantly broken. For example, hashtags allow people to jump out of their circle of friends and meet strangers at a more public level.

Accordingly, boyd and Ellison also gave a new definition of social networking site:

Social networking site is a networked communication platform, in which participants (1) have a unique and identifiable personal homepage, which includes the content provided by users themselves, the content provided by other users, and the data content at the system level (2) can publicly display their social relationships and be browsed and shuttled by others (3) can consume, produce and/or interact with the content stream provided by contacts in the site.

This change in technology and culture can also be reflected in the purport of researchers, such as algorithms and privacy, tag community and other research topics have gradually emerged and highlighted. Of course, even if the definitions provided by boyd and Ellison are updated, it has been seven years since this article was written. What changes have taken place in the characteristics of social networking sites? What surprises can these changes provide for our research and thinking?

From this point of view, American scholar Jeff Pooley is right, and communication research is destined to be a humble undertaking, because the continuous updating and iteration of technology will make us push a stone up the mountain like Sisyphus in Greek mythology, and then see it roll back again and again until forever.

Note: It should be noted that the two authors used "Social Network Site" instead of Social Media. If we make a diachronic analysis of the researcher’s choice of "wording", we will find the characteristics of the times. Between 2003 and 2008, the word "social networking site" was used twice as much as "social media" in research papers. However, from 2009 to 2014, this relationship was reversed, and social media has largely replaced the term "social networking site". Social media is the result of the continuous expansion of technology developers. Compared with social networking sites, it has a wider extension, or social networking sites have now condescended to become a subset of social media. See McCay-Peet & Quan-Haase, 2017.

For non-territorial network infringement information, timely submit it to the Central Network Information Office in accordance with relevant regulations and procedures.

(fifteen) improve the reporting and verification mechanism.Broaden the working ideas, innovate the methods of proof, enrich the forms of proof, reduce the difficulty of reporting by enterprises, and enhance the feasibility of reporting by enterprises. Sort out and summarize the dominant types of network infringement, such as insulting and abusing the network ecology, misleading public opinion out of context, and counterfeiting and counterfeiting illegal websites without filing, and clarify the specific circumstances without proof from judicial, administrative and other state agencies. Explore the effectiveness of third-party professional organizations, industry standards, legal opinions, audit reports, public service platform query results, and source media information in network infringement proof. Establish a linkage and coordination mechanism with the functional management departments of enterprises, analyze and judge important issues and major clues, make overall plans, form a joint effort, and create favorable conditions for rapid verification and timely disposal.

(sixteen) to strengthen the reporting policy guidance.Take the initiative to serve first, and actively find ways and solve problems for enterprises.

In accordance with the principle of "complying with laws and regulations, effectively guiding and standardizing channels", properly handle the reports of rights and interests disputes involving labor, contracts, equity, property rights, debts and consumption according to law. Set the reporting conditions reasonably, standardize the reporting behavior of enterprises, and prevent the abuse of reporting rights and disrupt the reporting work order.

V. Compacting the main responsibility of the website platform

(eighteen) strict supervision and inspection.Adhere to the combination of comprehensive inspection and key inspection, comprehensively inspect the reporting of network infringement information on the local website platform, and focus on the reporting of explicit network infringement information that the website platform fails to timely handle feedback in accordance with relevant laws and regulations. Establish a problem account, pay close attention to the implementation of rectification, and strengthen disciplinary punishment for website platforms with weak main responsibility and frequent network infringement problems.

(nineteen) set up a complaint window.Explore the establishment of an online complaint acceptance window for netizens, and promptly handle complaints from netizens about the untimely handling of online infringement information by local website platforms and the inadequate work of safeguarding netizens’ legitimate rights and interests. Standardize complaint handling procedures, improve complaint handling measures, and publish complaint handling methods. Establish a complaint handling inquiry system to improve the quality and efficiency of complaint handling. Improve the evaluation system of network infringement information reporting on the website platform, introduce mass evaluation parameters and indicators, and carry out mass satisfaction evaluation.

(20) Promote information disclosure.Guide the local key website platforms to establish a notification mechanism for the acceptance and disposal of normalized network infringement information reports. Use all-media methods, publish in a prominent position, and deeply analyze community rules such as acceptance process, judgment criteria, and processing time limit to guide netizens to report accurately and effectively. Publish the number, measures and typical cases of reporting and handling network infringement information, and accept public supervision. Publicly report the disposal of hot infringement incidents and respond to the concerns of netizens.

(twenty-one) to improve the disposal effect.Guide the website platform to improve the measures for reporting and handling classified network infringement information. Establish a fast-track mechanism to accept and deal with explicit network infringement and report with clear facts and sufficient evidence at the first time. Establish a "time-limited private" mechanism, and take "private" measures for infringing information with strong timeliness and long proof time, which may have a greater negative impact on informants, so as to block the sharing and dissemination of relevant information in time and provide a time window for informants to complete proof. Establish a "dispute label" mechanism, and take measures such as setting up "content doubt labels" or "linking parties’ response statements" for infringing information that has not been fully confirmed, so as to guide netizens to objectively judge and prevent infringing information from misleading public opinion.

VI. Organizing implementation

(twenty-two) to strengthen organizational leadership.Improve the political position, fully understand the significance of doing a good job in reporting network infringement information, and regard the reporting of network infringement information as the key task of network management, and pay close attention to it constantly. It is necessary to carefully plan and deploy, formulate work plans, clarify objectives and tasks, and refine work measures. It is necessary to seriously organize the implementation, compact the responsibilities of all parties, and make solid and orderly progress to ensure effective results.

(twenty-three) focus on demonstration and guidance.Adhere to the combination of comprehensive deployment and pilot-driven, carry out pilot demonstration work around key tasks and key initiatives, encourage innovation in ideas, initiatives and mechanisms, sum up and promote excellent practices and typical experiences in a timely manner, and actively cultivate and form a number of brands that meet the characteristics of the times and are close to the needs of the masses.

(twenty-four) to strengthen team building.Fully equipped with strong work force, strengthen ideological tempering, enhance the sense of purpose, and cultivate the spirit of serving the people. Strengthen practical training and business training, improve legal literacy and media literacy, enhance the skills and ability to serve the people, and strive to build a high-quality professional work team with fine business, strong ability, discipline and clear bottom line.

(twenty-five) to strengthen publicity.Strengthen online publicity, continue to carry out thematic publicity, effectiveness publicity and typical publicity, and present the work of reporting online infringement information in a three-dimensional way through various means such as audio, video and graphics. Strengthen offline promotion, organize the publicity of network infringement information reporting into grassroots, communities, schools and enterprises, and continuously expand the public awareness and social participation of network infringement information reporting.

　　If you retire in 20-30 years, how much pension can you expect to receive? The official data is coming! Yesterday, the national social insurance public service platform was put into trial operation. According to the experience of Beijing Youth Daily reporter, the platform not only needs to input relevant data such as my monthly payment salary and actual payment years, but also has three unknown variables such as "average salary growth rate of employees in the future (%)", "future personal account bookkeeping interest rate (%)" and "future payment salary growth rate (%)", so the calculation is not the actual pension amount, but more a scientific prediction for the future.

　　The official helps you predict how much pension you will receive.

　　The national social insurance public service platform (http://si.12333.gov.cn) has been put into trial operation. The platform can provide social security annual enrollment information inquiry, treatment qualification authentication, pension calculation, social security relationship transfer inquiry, remote medical inquiry, overseas exemption application, social security card and electronic social security card status inquiry, etc., all of which are national and cross-regional services.

　　The website platform provides two registration methods, one is according to the ID number, and the other is according to the social security card and social security bank card.

　　The reporter login test of Beiqing Daily takes only 1 minute, which is convenient and quick, from inputting information to inputting mobile phone number, waiting for receiving SMS password and completing registration.

　　The registered login successfully entered the column of "Pension Calculation", and the webpage of "Calculation of Pension Insurance Benefits for Urban Employees" was displayed. You can select "Employees of Urban Enterprises", "Individual Industrial and Commercial Households or Flexible Employed Persons" according to the insured type, and the data can be automatically predicted.

　　According to the information entered in the dialog box, the reporter of Beiqing Daily took a 40-year-old man as an example. The expected retirement age was 60 years, and the actual payment period was 15 years, which was deemed as the payment period of 15 years. At the end of last year, the personal account deposit was 180,000 yuan, and the average monthly salary of employees in the insured place (Beijing) last year was 8,467 yuan (released by the Statistics Bureau), and my monthly salary was 10,000 yuan, while "the average salary growth rate of employees in the future (%)" and According to systematic calculation, a 40-year-old man with a monthly income of 10,000 yuan will retire in 2039, with a monthly basic pension of 22,217 yuan.

　　What is the "personal account bookkeeping interest rate"

　　It is worth noting that the substitution of the three variables about future expectations will have a great impact on the prediction of future pensions.

　　Let’s take a 30-year-old man as an example. He is expected to work until he is 60 years old, and his monthly salary is 20,000 yuan. If the average wage growth rate of employees in the future (%) and the future contribution wage growth rate (%) are 10% and 5% respectively, he may have a pension in the future by substituting 3%, 5% and 8% into the future personal account charging rate (%). That is to say, when retiring in 2049, the insured person’s expected monthly basic pension is about 59,000 yuan to 71,800 yuan.

　　"Bookkeeping interest rate of personal account" directly affects the amount of future pension. The General Office of the Ministry of Human Resources and Social Security and the General Office of the Ministry of Finance issued the "Notice on Announcing the Bookkeeping Interest Rate of Personal Accounts of Basic Endowment Insurance for Employees in 2018", which announced that the bookkeeping interest rate of personal accounts of basic endowment insurance for urban employees (including basic endowment insurance for government institutions and enterprise employees) was 8.29% in 2018.

　　Bank time deposit interest rate in 2018: one-year fixed annual interest rate is 1.75%, and three-year fixed annual interest rate is 2.75%; The average yield of some bank wealth management products is about 4%. This means that under the same principal, the interest income of personal account of endowment insurance is 4.73 times that of regular deposit in the bank for one year and 2.03 times that of purchasing bank wealth management products.

　　The Ministry of Human Resources and Social Security pointed out that the bookkeeping interest rate of individual accounts for employees’ basic old-age insurance is announced by the Ministry of Human Resources and Social Security and the Ministry of Finance every year. The determination of bookkeeping interest rate mainly considers factors such as employee salary growth and fund balance, and is adjusted through reasonable coefficients, which shall not be lower than the bank time deposit interest rate.

　　The reporter of Beiqing Daily noted that in 2016 and 2017, the bookkeeping interest rates of personal accounts of basic old-age insurance for urban employees (including basic old-age insurance for government institutions and enterprise employees) were 8.31% and 7.12%, respectively, which were much higher than the deposit interest rates of banks in the same period.

　　There are also functions such as querying the status of social security cards.

　　It is reported that the platform will first provide the functions of social security annual enrollment information inquiry, treatment qualification authentication, pension calculation, social security relationship transfer inquiry, medical consultation in different places, overseas exemption application, social security card and electronic social security card status inquiry, etc., to achieve nationwide cross-regional services.

　　At present, 25 provinces have completed the docking of some areas with the national social insurance public service platform, and 22 provinces provide pension insurance benefits calculation services. Among them, 13 provinces will also provide personalized measurement services.

　　Data show that by the end of June, the number of people participating in basic pension, unemployment and work-related injury insurance in China was 947 million, 200 million and 245 million respectively, an increase of 4.43 million, 3.28 million and 6.5 million respectively over the end of last year.

As the first model of the brand, the Leopard 5 under BYD Equation Leopard is positioned as a new energy hard-core off-road medium and large SUV, which will be equipped with non-loaded body and plug-in hybrid system. Among them, the new DMO super hybrid off-road platform will be the first technical trump card of Leopard 5. What are the highlights of this technology? Let’s take a look at it first.

● The latest information of equation Leopard 5.

　　As the first model of Equation Leopard brand, Leopard 5 manufacturers are still very cautious about its information disclosure. Judging from the official information released at present, the new car is built on BYD’s new DMO super hybrid off-road platform, positioned as a medium and large SUV, adopting a design language called "Leopard Aesthetics" and equipped with Yunqi -P intelligent hydraulic body control system. The price of the new car is expected to be around 400 thousand yuan, and the delivery will be completed within the year.

　　In terms of performance configuration, Leopard 5 is the first model equipped with BYD’s new DMO super hybrid off-road platform, and Yunqi -P intelligent hydraulic body control system is also equipped. At the same time, the new car will be equipped with two motors and three differential locks (including electronic differential system), which will further enhance the power and the upper limit of extricating from difficulties. In addition, the Leopard 5 will adopt a vertical engine layout and have a comprehensive endurance performance of 1200km. The new car is expected to be unveiled at the upcoming Chengdu Auto Show, and interested friends can pay attention to it.

● DMO super hybrid off-road platform

　　The black technology on Leopard 5 is quite rich. In addition to the Yunqi -P intelligent hydraulic body control system (portal), it also adopts a brand-new DMO super hybrid off-road platform, which is the key technical support for Leopard 5 to have super off-road capability.

　　Leopard 5 supports fast charging, and it takes only 16 minutes to charge the battery from 30% to 80%. In the case of full oil and full electricity, the comprehensive cruising range exceeds 1200km. Oil and electricity can be used, and long battery life will help users travel all over the country.

■ Longitudinal engine hybrid system

　　"DM" in DMO super hybrid off-road platform refers to BYD DM dual-mode hybrid technology; And "O" means Off-Road, which means off-road. Taken together, DMO is the abbreviation of Dual Mode Off-Road, which is a set of hybrid electric platform technology specially developed for off-road

　　At the same time, the longitudinal engine also reserves more space for the layout of the double wishbone independent front suspension and the cloud -P system, which is a scheme choice after weighing the advantages and disadvantages of many parties.

■ EHS hybrid special gearbox adopts a new design.

　　In addition, although DMO and DM-i both adopt the configuration of double motors in series and parallel, their EHS hybrid gearbox designs are quite different. At present, BYD has not disclosed the specific structure of the EHS hybrid gearbox on the DMO platform.

　　SiC silicon carbide power semiconductor components are also one of the necessary technical configurations for the 800V voltage architecture that is being popularized. Leopard 5′ s EHS hybrid gearbox is also integrated with electronic differential system for the first time, which can actively lock when one wheel slips/idles, transfer the driving force to the wheel with adhesion, and improve the passability of the vehicle under complex off-road conditions.

■ Adapted to 1.5T and 2.0T engines.

　　DMO platform models will be equipped with 1.5T engine or 2.0T engine, of which the maximum power of 1.5T engine is 143kW and that of 2.0T engine is 180kW, and the thermal efficiency of both engines will exceed 40%.

　　Leopard 5 will be equipped with a 1.5T engine. As can be seen from the engine exhibition at the conference site, this 1.5T engine adopts advanced technology configurations such as intake/exhaust variable timing valve system (the intake valve timing adjustment mechanism is in the form of motor control, which can quickly adjust the intake valve timing phase at a large angle to realize Miller cycle working mode with expansion ratio greater than compression ratio), cylinder head with integrated exhaust manifold, direct injection in high-pressure cylinder and pulley-free design.

　　This 1.5T engine can achieve very high thermal efficiency in some working conditions, thus further reducing the fuel consumption when the engine (driving generator) generates electricity and when the engine directly drives the vehicle.

■ Low gear and differential lock

　　As mentioned earlier, in order to realize the four-wheel drive function, Leopard 5 has arranged a motor on the rear axle, which has a peak power of 285kW and a peak torque of 400N·m, and its power output is stronger than that of the front axle drive motor.

　　Because Leopard 5 has no central transmission shaft, its front axle power and rear axle power are decoupled mechanically, which gives great freedom to the distribution of front and rear axle power. When the power of the front and rear axles of Leopard 5 is distributed at 50:50, it is equivalent to locking the "central differential lock", which can make the best use of the road auxiliary force of the upper four wheels and further improve the vehicle’s ability to get out of trouble.

■ Battery pack arranged on the chassis

　　The battery pack of Leopard 5 is arranged between two longitudinal chassis beams. BYD officially calls this design "CTC", that is, the battery chassis integration of Cell To Chassis. Leopard 5 has a high-strength double-layer protective plate at the bottom of the battery pack, which can resist the impact energy of 1200J J.

　　Leopard 5 adopts BYD’s unique blade battery technology, and the battery level can achieve high safety without explosion and fire in the acupuncture test. The direct cooling and direct heating technology of heat pump is superimposed with active and passive temperature equalization design, so that the battery pack of Leopard 5 can adapt to different temperature environments from -40℃ to 60℃.

　　At present, most models sold by BYD are designed with single-layer blade batteries. It is believed that this double-layer blade battery design will become more and more common as BYD’s new cars with non-loaded bodies are listed one after another.

■ Front and rear double wishbone suspension system

　　The front and rear suspensions of Leopard 5 are in the form of double wishbone, and the stout control arm gives people stronger confidence in reliability and durability. This suspension system provides a good hardware foundation for Yunnian -P intelligent hydraulic body control system.

　　Yunqi -P can adjust the height, damping and stiffness adaptively, and has the function of four-wheel linkage. The system can realize the height adjustment range of more than 200mm, and support the functions of extreme extrication, camping leveling, convenient fetching and so on. At the same time, the multi-damping mode adjustment of urban driving gives better consideration to maneuverability and comfort.

■ It took 4 years to develop, covering 150 off-road working conditions.

　　Leopard 5 has been developed for 4 years, covering more than 30 off-road venues and 150 off-road conditions in China, with a cumulative test mileage of more than 1 million kilometers. Under various off-road conditions, Leopard 5 has a bright performance.

■ Leopard U-turn function

　　Leopard 5 supports the "Leopard U-turn" function. By making the front and rear wheels at diagonal positions rotate in opposite directions, the turning radius is reduced to 3.4m on off-road roads with relatively low adhesion, which makes it easier for vehicles to pass through some narrow intersections.

　　This working mode of reverse rotation of front and rear wheels is difficult to realize in ordinary fuel four-wheel drive vehicles, because these vehicles are driven by mechanical means, and the power of front and rear axles is coupled. Only after the dynamic decoupling of the front and rear axles is realized, can the leopard-like U-turn functions such as looking up at U8 and Leopard-5 be realized.

■ Support the car to charge the car

　　Leopard 5 supports 20kW in-situ charging function, that is, let the engine drive the generator to generate electricity, and charge the battery pack with 10% of the electricity in 10 minutes.

　　It is worth mentioning that, like other hybrid models of BYD, Leopard 5 also uses 12V Ferrous lithium phosphate starter battery to replace lead-acid battery, which is more environmentally friendly (completely lead-free) and has a longer service life (the same life as the whole vehicle). BYD is the first manufacturer in the world to adopt this technology, which has been used for 6 years.

■ High-voltage electric winch

　　Winch is a self-protection and traction device for off-road vehicles, which can be used for self-rescue in harsh environments such as snow, swamp and desert, and may be used for clearing obstacles, dragging articles and installing facilities under other conditions.

● Full text summary:

　　The rise of the trend of pursuing individuality and longing for a long journey and the maturity of new energy technology have made the market segment of new energy hard-core off-road SUV heat up rapidly, and new models have sprung up. Most of these new products are China brand products. Equation Leopard 5 is a model born for this era.

　　An IPhone +QQ music player+digital audio standing wave processor+world cable box, with a simple and unexpected combination scheme, won the attention of countless media, industry insiders and experienced fans at the 2017 Shanghai International HI-FI Audio Exhibition (SIAV), and stood out from the noisy exhibition with its shocking playing conclusion.

　　Genesis (Singapore) Technology Co., Ltd. and Xuran Group, following the discovery trip in Hai Yin, Guangzhou on April 16th, once again took advantage of the Shanghai International HIFI Exhibition to release the new digital recording and broadcasting method of "Discovery, New Sound Machine"-"Digital Audio Solution". Under the witness of more than 60 media, nearly 3,000 people in the industry and experienced friends, Xuran Group demonstrated to the media and the public how digital audio solutions can solve the pain points in the audio industry from the root and promote a great leap in sound quality.

　　Only IPhone +QQ music player +KEF speaker, such a simple digital audio playback scheme, after loading the digital audio solution, that is, the world cable box and digital audio standing wave processor, the sound quality can reach HI-END level. At the event site, we showed: IPhone +QQ music player +KEF speaker, and the comparison between the loading and unloading of the world cable box and the digital audio standing wave processor. The participants at the scene were deeply shocked by the conclusion of playing QQ music after loading the digital audio solution. Some people in the industry even felt that this would rewrite the history of the audio industry and was definitely a subversive innovation. The veteran enthusiasts at the scene even bluntly said that they "don’t have to buy any vinyl or CDs anymore", and even felt that their playing conclusion far exceeded the effect of CD playing, and they were willing to pay for such a conclusion. There is no doubt that the digital audio solution can greatly improve the sound quality of QQ music playback because of the empirical comparison on the spot and the reaction of the participants.
