Recently, whether fans have aroused conflicts with their peers by reporting the fan fiction database website-AO3, or fans of the draft variety "Creation Camp 2020" and fans of the same type "Youth has You 2" have begun to "break their heads".（battle）The "rice circle" caused quite a stir on the Internet, and many idols were forced to "go out of the circle". However, why do fans always have fierce contradictions? Can fan culture be compatible with popular culture? Where did the original "rice circle" culture come from?

In order to answer a series of questions about "rice circle culture", Huayi Brothers Research Institute deeply explored the fan culture. This paper will focus on the origin, development process and characteristics of fan culture, and deeply analyze the circle and structure of entertainment rice circle culture in the mainland.

Origin: Influenced by the cultural circles of East Asia and Europe and America, China’s "fan culture" has taken shape.

The worship and pursuit of idols are rooted in human nature, but the formation of fan culture is not only based on feelings, but also influenced by social, economic and cultural aspects. Internationally, the prevalence of consumerism in the 1980s provided a fertile ground for the outbreak of the fan community, which also attracted academic attention to this cultural phenomenon. From text deconstruction and reconstruction, to field and social class, to emotional pursuit and psychoanalysis, the relationship between fan culture and many key fields has gradually become clear.Numerous studies of fan culture in the context of mass culture, media communication and economic power show the integration of fan culture and the complexity of its internal mechanism.

Due to the different basic economic environment and media preference, foreign fan studies can not fully explain the current situation of domestic fan culture. However, it is undeniable that China’s fan culture was really influenced by the East Asian cultural circle in its early days. Even today, China’s fan culture still contains a series of fan behaviors such as Japanese "house" culture and Korean idol culture, such as "calling", "playing the list" and "supporting". With the acceleration of internationalization, the frequency of the word "European and American circle" in fan culture has gradually increased, and the new fan culture has impacted and changed the original domestic fan culture. AO3（Archive of Our Own）And other more open fan creation websites have therefore entered the field of vision of domestic fans and become a gathering place for some domestic fans.

Change: from "groupies" to the establishment of "rice circle"

China’s modern fan culture took shape in the middle and late 20th century. Teresa Teng, Little Tiger, Chow Yun Fat and other Hong Kong and Taiwan stars had a large number of fans, and the appearance of Cui Jian and other rock stars also met the spiritual needs of young people at that time. However, during this period, fans’ idolatry was confined to the mechanism of one-way communication, and fans’ behavior was mainly to receive information. The term "groupie" also came into people’s field of vision.

In 2005, Super Girl’s program exploded, driving fans to become a unique social group and cultural phenomenon into the mainstream. Groups such as "corn", "bean jelly" and "box lunch" have entered people’s field of vision with an unprecedented speed and high-profile posture, breaking the traditional impression of groupies in the past. They not only went to the show site to hold up light signs and shout uniform slogans to cheer for the players they supported, but also expressed their attitudes through SMS voting and even called for more people to vote through a large number of promotional materials. Not only did it help your favorite players to "get through the customs" round after round, but it also made the talent show a carnival of "participation by the whole people".①

Since then,With the development of new media environment, fan culture has also undergone a new transformation: the original one-way communication between fans and idols has changed into two-way communication, and virtual communities have improved the scale and organization of fan groups.Weibo has become a gathering place of fan culture because it provides a platform for direct communication between fans and idols, which satisfies the imagination that fans can contact idol life and have direct dialogue with idols. Even to some extent, this kind of imagination is built to satisfy the psychology of fans.Pseudo interactive relationship, and thus produced some discordant sounds. On the other hand, the network has further increased the scale of the fan base, becoming a so-called "rice circle" and creating its own discourse system and power system. Fans can quickly locate their peers with the same hobbies through the internet, and fan activities are more organized through the internet. At the same time, the emergence of professional websites and apps in idolize has further promoted the commercialization of fan culture and spawned more diverse fan activities.

Driven by the trend of consumer culture, the society has changed from production-oriented to consumption-oriented, and the fan economy has flourished with the popularization of fan culture.Fans are not only the main body of culture, but also the main body of economy, playing a huge role in the consumer society.Therefore, the emergence of "professional fans" is logical. Professional fans either earn money through fan activities, or cooperate with brokerage companies and cultural companies to operate fans to get paid. While the commercial value of fans is improving, the guidance of relatively negative economic demand to excessive behavior is also emerging at this time.

From the changes of fan culture, it is not difficult to find that the balance of power between fans and idols is unconsciously tilted. With the advent of the era of "star-making" fans, "flow" has become the lifeblood of grasping the idol cause, and the power of fans has been further enhanced, even reversing beyond the idol itself.The industrialization of idols has caused a sharp increase in the number of idols, an increase in the mobility of fans, a change in the buyer’s market position, and fans have more right to speak and decide.However, the strong capital in the layout of big entertainment has come to an end, and a new party has been added to the idol-fan system, and the game is more complicated and intense. The "rice circle" of social network platform has expanded the application field of fan culture, and more and more people have noticed the strong emotional connection and high user viscosity of fan culture. As a unique community structure, fan culture is highly involved in today’s social structure and activities.

Ecological characteristics of Chinese vermicelli

Refined fan operation: strict organization

Under the great influence of the fan economy, the fan ecology of fans is no longer an initial "atomic" individual activity, but an organized and distributed collective activity. Fan operation is no longer an industry secret, as long as you mix for a while, "solid powder"(Maintain existing fans by communicating with them more), "powder abuse"(Stimulate fans’ desire for protection by shaping the image of idols being bullied, so as to strengthen emotional ties), "purification"(Cut off the relationship between the two idols who used to be "cp" in film and television works, and convert the double fans into single fans, that is, "only fans")"explosion-proof"(prevent the same type of idol from exploding)Waiting for the routine, even if it is "loose powder"(Fans who have not participated in any support meetings and fan groups)And I know it.

The refinement and specialization of fan operation is inevitable. First, spontaneous fan behavior is prone to irregular behavior because of emotional and irregular behavior, which has a negative impact on idols, so it needs correct guidance; Second, the subjects associated with the idol industry are becoming more and more diverse, and the cooperation between brokerage companies, content production companies, brands and video platforms requires the guidance of professional teams to maximize benefits; Third, the internal attributes of fans are different, and their preferences and activities are different. Professional teams can allocate resources more reasonably to meet the psychological needs of all parties.

In terms of organizational structure, the management of all fans consists of three parts, namely, the internal class management of fan organizations, the fan management with the brokerage company as the core and the commercial value of idols as the guide, and the professional fan companies that focus on the operation of fans as a whole rather than a specific idol fan group, such as Super Star Rice Ball.

Every fan activity, the brokerage company guides the "big powder"(Opinion leaders among fans), "job powder" and the management of the support club, disclose the information and the purpose of the support activities in advance, and these fans will pass the information to the fan group. The activities within the fan group are carried out in the form of "multi-point gathering", with "big fans", individual stations and support clubs in different regions as the multi-point core, and ordinary fans are gathered for large-scale support. In this process, professional fan companies not only play an auxiliary role, but also may be the purpose of some kind of fan activities, such as learning about idol dynamics through fan apps or playing on fan apps.

"Heterotopia" in Rice Circles: Community and Exclusion

heterotopias co., ltd creativity | plan | dissemination（heterotopias）It’s Foucault.（Michel Foucault）A kind of observation of society proposed is different from a fictional utopia. Heterotopia is connected with the real place, but it is different from the ordinary cultural space.The virtual space "rice circle" formed by fan culture conforms to the characteristics of "different countries";The tendency of the population, its role in society, its juxtaposition in space, its combination with the fragments of time, and its opening and closing system.

"Fanhuan" is a collection of groups, which has crossed the barriers of time and space, has rules and thinking different from the actual rules, and has a certain threshold to enter Fanhuan.

Promoting fans from individuals to relatively stable communities is a variety of fan activities in the multimedia channel environment. Collective labor, such as hitting the list and rushing sales, has stimulated the emotional connection of the group, such as successfully helping their idols get the first place in the list, which has increased the individual’s recognition of the community. In order to prevent the loss of fans, fan activities are usually regular or frequent. In this case, the community can maintain relative stability. At the same time, more and more communication channels, including Weibo fan groups, WeChat groups and QQ groups, provide the foundation for closer and personal contact, and the doping of personal emotional contact increases the stickiness of the community.

As an independent group, "rice circle" has its own independent discourse system and rules, and its representation is often called "rice circle language" and "rice circle thinking".Abbreviations often seen in Weibo are typical of rice circle language: behind the abbreviations of people’s names is the logic of rice circle to prevent fans from searching the square for comments and attacks; y1s1(there is a saying)、dw(poison only means extreme powder only)、bp(Bai Piao, a fan who doesn’t spend money on idols)These words, which can be understood by internal members and confused by non-rice circle people, not only establish a barrier between rice circle and the outside, but also consolidate the sense of group identity within the community.

However, the "alien state" of rice circles is in contact with the mainstream culture, and it is not completely independent, so there is also a conflict between the unique thinking and universal values of rice circles.In the context of rice circles, "powder is black" and "comparison is stepping on" is somewhat mismatched under the dualistic popular culture that does not agree with "black is white". However, the rice circle culture really affects the language form of Chinese network and the thinking logic behind it, so it is often criticized.

Fans are extremely exclusive, which may be due to the fierce competition in the idol industry.At present, among the top idols, basically every one has had a fierce fan struggle with several others. The reasons are nothing more than fighting for the first place, for endorsement resources, and for traffic. For example, because of similar fame paths.(Acted in a beautiful drama, and became popular because of his outstanding acting skills)And similar images, fans of Sean Xiao and Zhu Yilong once attacked each other. Even because of the different attributes of fans, "only powder"(fans who only like one idol)"Tuanfen"(Like a fan of an idol group), "cp powder"(fans who like a real couple or an imaginary couple)There are also conflicts between them. Idol groups debuting in the recent draft, such as Rocket Girl and NINE PERCENT, often have conflicts with individual fans because of different interests.

▲NINE PERCENT　

The exclusiveness of fan culture is not only reflected in external disputes, but also caused by the strict institutional class at home.Although only gathered for the same hobby.Interest groupHowever, there is a hierarchical difference in the right to speak among fans. In fan organizations, it is common for the management to hold a group. When the upper level agrees, fans with different views will be kicked out of the support club or support group to ensure the "harmony" of the organization. "big powder"(opinion leaders among fans, often UGC creators, paragraph players or professional fans)Our views affect the wind direction of the whole fan community. Once there is an abnormal sound, it is either ignored because the sound volume is too small or destroyed because of the attack of "big fans". Although rice circles have begun to realize the negative impact of "big powder", it is unrealistic to put an end to the impact of "big powder" because of its strong functionality in the current fan community structure.

Conclusion:

With the development of Internet, the development of entertainment industry and the changes in the way stars debut, China’s fan organizations have evolved from the "groupie" period to the "rice circle" era, and the rigor and organization of this organization have also been significantly enhanced, and its influence has gradually expanded, becoming a large group organization that cannot be ignored in today’s society.

People’s Daily Online, London, April 24 (Yang Bo, Daytime Travel) The history of garbage recycling in Britain can be traced back to before industrialization, when waste from burning wood and coal was collected and used as the basic material for making bricks. However, the recycling at that time was because the economic advantages of renewable resources were higher than those of original materials, and there was a lack of public waste removal system in densely populated areas.

In Britain and Ireland around 1800, beverage bottles were recycled by some beverage manufacturers.

In 1813, Benjamin Raul combined rag fibers with raw wool to pass off as wool, which can be regarded as a kind of "garbage recycling", but this material made the inferior industry in West Yorkshire last for nearly a hundred years from the early 19th century.

In the past ten years, Britain has introduced some new regulations to encourage more recycling. These measures include imposing fines on those who do not reduce household waste, and putting more emphasis on sorting waste into different recyclable materials. Each local authority has different rules.

Now about 177 million tons of waste are produced in England every year. In order to reduce expenditure and produce waste, the British government issued the Waste Prevention Plan for England in 2013. In May 2014, the "Innovation of Waste Prevention Fund" funded by the Ministry of Environment was launched.

The government will require enterprises to be responsible for the products they produce, and the law also requires some enterprises to ensure that part of the products they sell are recycled and reused. These products include packaging, batteries, electrical and electronic equipment, vehicles and so on. At the same time, the government cooperates with the garbage industry through the "waste management responsibility agreement" to ensure that enterprises recycle as simply as possible and improve household recycling and waste collection. Laws have also been introduced to crack down on crimes, including illegal dumping of waste, operation of illegal waste management sites and illegal export of waste.

Domestic waste is subdivided into three categories.

In Britain, the classification of domestic waste recycling is very detailed, and the "Domestic Waste Recycling Act 2003" requires governments all over England to provide at least two kinds of recyclable materials collection services to every family.

So now we can see that in a single-family British family with a garden, there are usually three trash cans in front of the door or backyard. The colors of the lids are different, and the types of garbage inside are different.

For example, in some places, the trash can with black lid is used to hold "general garbage", the trash can with blue lid is used to hold "recyclable garbage", and the trash can with green lid is used to hold garden and kitchen waste. In another area, the color may be different from the barrel to the lid.

In addition to general garbage, the other two kinds of garbage are classified strictly. "Recyclable garbage" can be glass bottles, paper products, cans, degradable plastic bags, etc., while "garden or kitchen waste" can only be dead leaves, weeds or food, but not soil, stones and packaging. According to the specific classification regulations, the government will issue special leaflets and stuff them into users’ mailboxes on a regular basis or directly stick them on users’ trash can lids by garbage collectors.

When it comes to the division of plastic bags, it is difficult for ordinary people to quickly identify whether they are recyclable. Fortunately, most of the packaging of articles will clearly indicate whether the packaging can be recycled. It’s just that not all people will be "selective" when throwing garbage, so there are always people who intentionally or unintentionally "foul". Once they are discovered by the "eye-catching" recyclers, you will usually "harvest" a "warning sheet" on the lid of your trash can.

People who live in apartments do not have a garden, so they need only separate the recyclable garbage list. There is a special garbage station next to the apartment, and the oversized garbage bins inside are also classified.

Generally, special garbage trucks and workers will come to collect the three kinds of garbage at a fixed time every week. The night before, people just need to push the garbage bins usually stored in the backyard or by the door to the roadside near the main street, and the next morning, they may still be dreaming, and they can hear the sound of the roaring garbage trucks coming.

To "enjoy" such on-site service, you need to pay a certain fee, which is usually included in the monthly council tax collected by local governments. However, the budget of some places is relatively tight recently, so the recycling time of garden and kitchen waste is extended from once a week to once every two weeks.

Last year, there were news reports that families with children under three years old in a region of Wales had to provide their children’s birth certificates to collect diapers every two weeks, otherwise they would collect diapers together with domestic garbage every three weeks, which was said to be for the purpose of environmental protection.

Of course, if you don’t want to pay the garbage collection fee, there is a way. You can throw it directly into the nearby "garbage dump".

When I first entered this "garbage dump", I felt a sense of "dazzling", because the types of garbage inside were too fine. Recyclable paper products were divided into paper packaging, newspapers and magazines, and old clothes and sheets should be separated. In addition, there were cooking oil, batteries, small household appliances and so on. Once you saw that you were carrying the bag in the wrong direction, the staff next to you would come forward to guide you.

As for the "large-scale garbage" like old furniture, either make an appointment with a charity to collect it at home or pay someone to buy it. The cost may be higher than you think, and there is no service that can be sold as waste in China.

The policy focus shifts from punishment to reward.

Recently, the focus of Britain’s garbage recycling policy has shifted from punishing those who don’t recycle to encouraging more people to recycle through rewards.

WRAP, the waste and resources action plan, is a registered charity, which is jointly funded by several British government departments and the European Union.

Its website, Recyclenow, provides detailed guidance and suggestions to those who want to seriously classify garbage, and classifies recyclable garbage into six categories: sprays, food, plastic bottles, clothes, electronic equipment and medicines.

pressurized spray

For example, about 60% of waste such as used air fresheners is made of tinned steel, and about 40% is made of aluminum. Both metals can be recycled. It also contains some small plastic and rubber parts, including covers, valves and dip tubes, which can be extracted and fully recycled. If everyone in the UK can recycle an empty air freshener, the converted energy will be enough for the TV energy of 273,000 families.

food

Food recycling includes banana peel, leftovers, tea bags and so on. Usually, any cooked or raw food waste can be recycled, but it is necessary to ensure that all packaging, especially plastic packaging, is taken out.

There are several ways to treat the collected food waste. In some areas, it is mixed with garden waste and transported to local commercial composting facilities. This compost will be used in agriculture, landscaping and gardening. If food waste is collected separately, a method called anaerobic digestion is usually used to generate green electricity.

plastic bottle

It is estimated that Britain uses an average of 35.8 million plastic bottles every day, but only 19.8 million plastic bottles can be recycled every day, which means that an average of 16 million plastic bottles cannot enter the recycling station every day.

The recycling of plastic bottles requires emptying and washing articles, taking off the lid and squeezing the bottles to save space.

Clothing and textiles

Even damaged clothes and faded curtains, which are not suitable for reuse by others, can be recycled to create new items, such as cushions, cleaning cloths and industrial blankets for chairs and car seats. Charities everywhere in Britain recycle clothing and textiles, and different charities collect items slightly differently.

Some stores, such as H&M and Martha, collect old clothes in the store. Martha also collected it through charity partner Oxfam, and offered a discount the next time the donor went to Martha to buy it.

electronic equipment

Usually, when buying new electronic goods, stores will recycle old equipment, especially larger items, such as televisions and refrigerators and freezers. Other recycling methods include online junk exchange and selling websites. For unwanted mobile phones and tablets, some merchants can get cash or redeem gift certificates.

medicines and chemical reagents

Unopened, unused and expired drugs can be returned to the pharmacy for disposal. It is estimated that as much as 300 million pounds of unused or partially used drugs are wasted in Britain every year and cannot be recycled or reused. Therefore, the British medical system calls on people to think carefully before ordering duplicate prescriptions.

The road to comprehensive recycling is "long"

In addition to government regulations and services, it is equally important to raise people’s awareness of environmental protection and economy. For example, statistics for many years show that the amount of food wasted by the British is still amazing. In 2013, food worth 15.1 billion pounds was thrown into the trash can by the British. Statistics in 2014 found that up to 400 tons of food is still wasted every year, and the average person wastes up to 200 pounds of food every year.

With the continuous efforts of British government departments, the classification and recycling of garbage has made remarkable progress, but the overall household garbage recovery rate has been below 50%. According to the latest data from the Department of Environment, Food and Rural Affairs (Defra) of the British government, from 2000/01 to 2009/10, household recycling in the UK increased by 235%; In 2009/10, 23 million tons of domestic waste were generated, of which 9.4 million tons were recovered, reused or composted, with compost accounting for the largest proportion, accounting for 40% of the total. In 2015, the recycling rate of households in England was 43.9%, which was 0.9 percentage points lower than that of 44.8% in 2014. Also since 2011, the "domestic garbage recycling rate" was lower than 44% for the first time.

The British referendum decided to leave the European Union, which also brought certain policy uncertainty to garbage sorting and recycling. If Britain leaves the EU, all kinds of EU regulations and standards that regulate all walks of life will face the process of replacing them with Britain’s own. Whether to completely follow the original EU system or reset Britain’s own system will create a certain policy vacuum or delay in the short term, such as promoting garbage collection. Recently, British Prime Minister Theresa May announced that the general election will be held in advance, which will aggravate the uncertainty and delay of this policy to a certain extent. Although it will not necessarily affect the implementation of policies such as garbage collection, it will certainly have a certain impact on further promotion.

　　[car home Technology] I don’t know if everyone in front of the screen knows anything about the 100,000-class pure electric compact car. As far as the author is concerned, the competition of this class of cars is actually quite fierce. On the one hand, it is a price war, on the other hand, it is repeatedly involved in design, safety and configuration. In this class of cars, (|) successfully circled the powder with its retro and beautiful shape. Of course, we don’t talk about design today, but look at the scientific and technological strength behind this boutique car through actual disassembly.

● Five-ring body frame

　　The length, width and height of Wuling Binguo are 3950*1708*1580mm respectively, and the wheelbase is 2560mm. Thanks to its front-drive pure electric platform technology, the cabin space utilization can be maximized.

　　For small cars, consumers are not only concerned about the performance of their cabin space, but also extremely concerned about their safety. Binguo adopts a five-ring car body frame structure, which can increase the rigidity of the car body and improve NVH performance, and at the same time, it can quickly transfer collision energy when a collision occurs, reduce the intrusion of the passenger compartment and protect the safety of the passengers.

　　The A-pillar, B-pillar and sill beam constitute the thermoformed steel door ring, which can bear higher pressure and improve the torsional stiffness and safety of the car body. At the same time, the steel door ring of hot car can also improve the sealing performance and torsional stiffness of the car body, improve NVH performance and enhance ride comfort.

　　The energy-absorbing box can reduce the maintenance cost of low-speed (20-30km/h) impact, because the energy-absorbing function of the energy-absorbing box can avoid the damage of the longitudinal beam, and the damaged energy-absorbing box can be replaced separately.

　　According to official data, compared with the design of only the front finger beam and the front longitudinal beam, the triple frontal collision-resistant energy-absorbing structure design of Binguo can achieve a 15% improvement in energy absorption efficiency.

　　There is also a steel anti-collision beam at the rear of Binguo, but there is no energy-absorbing box between it and the body. Even so, the existence of the anti-collision beam can disperse the impact energy of the rear collision, thus reducing the damage degree of the rear collision accident to the vehicle.

● Robust chassis

　　Binguo adopts the suspension combination of front McPherson and rear torsion beam, which is common at the same level. Simple structure, durable leather and low manufacturing cost are a major feature of this suspension form.

　　Compared with the open beam, the closed torsion beam with variable cross-section improves the stiffness of the torsion beam by 41% and the bearing capacity accordingly, thus reducing the vibration and improving the ride comfort.

　　According to the manufacturer’s introduction, Bingo’s chassis adjustment style is tough, that is, to ensure ride comfort on the basis of achieving good support of the car body. Therefore, bingo will be more stable when driving at high speed, giving people more sense of security, and emergency lane-changing vehicles can also provide good support. Binguo 410km Linxi Exclusive Edition uses a brand-new motor with better performance, and its top speed can reach 130km/h, which is higher than that of other models with 100km/h and 120km/h, so it is quite necessary to match a robust chassis.

　　Compared with the 175 and 165 tire widths commonly used in the same class, the wider tread of Bingo standard tires is beneficial to improve tire grip, make the vehicle run more stably, and ensure sufficient braking performance.

　　In addition to making great efforts to filter the vibration of the chassis to improve NVH performance, Bingo also made a fuss about the details such as the sealing and sound insulation measures of the passenger compartment. Both the front and rear side doors of Binguo have two complete sealing strips to ensure the tightness of the passenger compartment and avoid the introduction of environmental noise and wind noise into the car. At the same time, the sound-absorbing cotton of the front and rear outer wheel covers of Bingo is made of non-woven fabric +PP+PET+ non-woven fabric, which can effectively absorb the tire noise and the noise generated when the suspension system works.

● Water-cooled flat wire motor and refined battery

　　Binguo 410km Lingxi exclusive edition adopts water-cooled flat-wire permanent magnet synchronous motor, which is a three-in-one design and integrates motor, electronic control and differential.

　　Compared with the round wire motor, the slot fullness of the flat wire motor is increased by 20%, the contact area between the flat wires is larger, the heat conduction is better, and the heat dissipation capacity is stronger. The power density of the flat wire motor is increased by 0.8kW/kg, and the high efficiency range is expanded by 11%, thus making the maximum efficiency of the motor more than 96%.

　　We can see that there is a cooling water jacket on the stator shell of the motor, and the cooling liquid will circulate in the water jacket, taking away the heat generated when the motor works, and improving the continuous high power output performance and durability of the motor.

　　Wuling’s refined battery should be familiar to all of you. I introduced this battery in detail in the technical article of Wuling Starlight (click to view).

　　The battery core of Shenlian battery can not catch fire or explode in the acupuncture test; In the shallow needling test (the steel needle penetrates 1/3 of the battery thickness), the battery can still discharge normally; When the battery cell is extruded and deformed by external force up to 40%, it can not catch fire or explode. The safety performance at the cell level is quite eye-catching, which is also the key factor for the high safety of Bingo battery system.

　　At the level of battery pack, Shenlian battery adopts a structure called MUST, that is, Multifunctional Unitized Structure Technology, a multifunctional integrated battery pack structure technology. The biggest feature of this structure is that the cells are put into the reinforced frame and then installed into the battery pack. This reinforced frame can improve the structural strength of the battery pack by 60%.

　　Battery packs have suffered a lot in the laboratory, and it is common to go to the mountains and go to sea. The whole package of Shenlian battery has been tested by temperature change test, water immersion test, high temperature acupuncture test, vibration test, bottom dynamic impact test and charge-discharge test.

More exciting videos are all on the car home video platform.

　　Like mainstream electric vehicles on the market, Bingo’s BMS battery management system also supports Che Yun Intelligent Collaboration. In addition to real-time monitoring of battery status at the vehicle end, all-weather and life-cycle second-level safety inspection will also be carried out in the cloud. When the system detects battery collision, stabbing or overheating, it will actively remind the driver to prevent problems before they happen.

　　According to the manufacturer, this can reduce the maintenance cost by 90%. At the same time, Wuling has also strengthened the training of battery maintenance in the 4S after-sales service system. I believe that in time, its after-sales service outlets will be fully equipped with power battery maintenance capabilities. Compared with the power battery specialized service that can be seen in the market now, it is obvious that the official after-sales service can reassure consumers.

　　In this regard, I also asked the engineer at the dismantling site whether there will be batteries in the form of direct cooling or water cooling with refrigerant installed on Bingo. The engineer’s reply is vague and only means "on the road". Perhaps in the future, Bingo with more powerful electric drive system will use direct cooling or liquid cooling battery system with active temperature control function, which is worth looking forward to.

● Full text summary:

　　Wuling Binguo, as a pure electric small car, has done its homework in terms of cabin space utilization and safety, completely dispelling consumers’ concerns about small space and insecurity of small cars. At the same time, the affordable price of 59,800-88,800 yuan, combined with its fashionable and beautiful shape, is a good choice for buying food scooters in the near future.

　　Corn is one of the crops with the largest sown area and the highest yield in China. Corn has a wide range of uses, not only as feed, but also for various industrial purposes, and provides high-quality protein and starch for human beings. The natural outcrossing rate of maize is as high as 95%, so hybrid seed production and special maize production need to be strictly separated. Conventional time and space isolation measures are time-consuming, laborious and difficult. How to realize corn non-isolated production in a scientific way is an urgent production problem. In general, both self-pollination and hybridization of maize can bear fruit, but there is a phenomenon that a few maize do not accept other maize pollen in nature, which is called unilateral cross-incompatibility (UCI) of maize. Some studies have reported three UCI loci, Ga1, Ga2 and Tcb1, which are composed of pollen and filament determinants respectively. According to the structure and function of UCI loci, maize in nature can be divided into three types: S type (Ga1-S, Ga2-S and Tcb1-S), which contains both pollen and filament determinant genes; M-type (Ga1-M, Ga2-M and Tcb1-M) only contains pollen determinant genes; Common types (ga1, ga2 and tcb1) contain neither pollen nor filament determinant gene. UCI controls the sexual transmission direction of haploid gametes and can be used for reproductive isolation between different types of maize.　
　　Chen Huabang, research group of Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, devoted himself to the study of maize one-way cross incompatibility, and reported the pollen and filament factor genes at Ga1 and Ga2 loci and their applications successively (Zhang et al., 2012；; Zhang et al., 2018，Chen et al., 2022； Cai et al., 2022）。 Recently, the team has once again made important progress in the study of maize incompatibility. In this study, the pollen determinant Tcb-m at Tcb1 locus was cloned. This is the "last" cloned determinant gene of maize incompatibility system. So far, all the key determinants of the three incompatibility sites have been cloned and verified, which laid the foundation for the study of commonness and specificity among maize incompatibility systems. On November 16th, related research results were published online in Plant Biotechnology Journal with the title of A Pollen Expressed PME Gene at TC B1 Locus Confers Maize Independent Cross-in Compatibility.　
　　It was found that the pollen factor Tcb1-M at TCB1 locus of maize encoded Pectin Methylesterases (PME), which was specifically expressed in the pollen of Tcb1-S materials. Studies have shown that the expression of Tcb1-m gene in common corn by transgenic method can make it pollinate and bear fruit for Tcb1-S type materials. Tcb1 locus and Ga1 locus are closely linked, and their pollen and filament factors are highly similar, and the two loci are in tandem repetitive relationship. However, Tcb1 locus only exists in the primitive ancestor of maize, and Ga1 locus exists in both maize and maize, which indicates that the two loci have differentiated and produced specificity after maize domestication. There are also a certain number of materials containing Ga1 or Ga2 loci in common corn in nature, which will reduce the application value of UCI loci in corn. In this study, the materials containing three sites were combined in different forms, and a polymer material containing two or three incompatible sites was created, which not only effectively hindered the pollen of ordinary corn, but also effectively prevented the risk of penetration of materials containing a single incompatible site, and further improved the application of corn incompatibility in non-isolated seed production. This study laid a material foundation for the mechanism analysis of incompatible systems.
