SLC, MLC or TLC?

　　I believe that some players who know a little about SSD have heard about SLC, MLC and TLC, and their impression of TLC should be synonymous with poor performance and short life. SSD relies on NAND Flash memory chip to store data, which is very similar to the U disk we use in principle. According to the storage principle of NAND Flash, SSD can be divided into SLC(Single-Level Cell), MLC(Multi-Level Cell) and TLC(Trinary-Level Cell).

　　In principle, SLC only stores 1bit of data in each memory storage unit, and there are only two charging values, 0 and 1. MLC stores 2 bits of data in each memory storage unit, and has four charging values of 00, 01, 10 and 11. It takes more time to access data than SLC, but its advantage is that it has higher data density and can reduce production costs. TLC stores 3 bits of data in each memory storage unit, and there are 8 charging values. In the process of use, in order to meet these 8 different voltage states, the main control chip needs to apply different voltage states, which takes longer to complete, and the result is slower access speed. However, the advantage of TLC is that it has the highest data density and the lowest cost, and it is also very easy to make a large-capacity SSD at a competitive price segment.

TLC is obviously different from MLC in life and performance.

　　Players talk about the color change of TLC, among which the slow reading and writing speed is not the main reason, and what is more worrying is the life of TLC SSD. Compared with MLC with 3000+ times and SLC with nearly infinite life, the theoretical erasure life of 1000 times is so short.

More advanced technology will make the original more fragile.

　　The former principle part briefly explains the working state of TLC SSD when it is used. With the development of semiconductor technology, the thickness of insulator silicon oxide is getting thinner and thinner. Every time SSD is written and erased, the process of applying voltage itself has physical losses. In addition, TLC needs to handle eight different voltages at the same time. The physical laws determine that electrons may be stranded in the silicon dioxide insulation layer. This will make each erasing time longer than the last time. With the longer use time, it will take longer and higher voltage value to reach the original voltage every time. The main control chip will also try different voltages when it detects that the original design voltage value is abnormal, which will further slow down the speed and bring further losses.

Why TLC is dominating SSD market?

　　Whether you want to admit it or not, although the players have a bad reputation for TLC, the SSD market is inevitably dominated by TLC SSD. Are products with obvious shortcomings such as short life and poor performance released to the market by major manufacturers just because of low cost?

　　In fact, the reason why TLC SSD now occupies most of the market share is that manufacturers have found a solution to the slow reading and writing speed and short life of TLC.

More components are accommodated through the multilayer stack structure.

　　First of all, the life-span problem is solved thanks to the 3D NAND structure. The original 2D NAND pursues smaller memory cells through more advanced semiconductor technology in exchange for larger storage capacity, which aggravates the short life-span problem for TLC. However, the idea of 3D NAND structure has changed, instead of pursuing smaller units on a plane, more units are put down by stacking and packaging, so the space saved can use relatively old processes. The advantage of using the old process is that the number of P/E erasures is greatly increased, and the situation of charge interference is also greatly reduced because of using the old process.

　　In recent years, the improvement of the main control chip by the manufacturer has further improved the service life of TLC, and has made progress in signal processing, algorithm and so on. So that today’s TLC SSD can also be on par with MLC in quality assurance.

Use part of TLC in SLC mode.

　　TLC belongs to a state of "treating the symptoms but not the root cause" in solving the speed problem. In principle, it is determined that the reading and writing speed of TLC can’t be faster than MLC or even SLC, but we don’t always read and write data with a very large amount of data. By turning a part of TLC into a cache area, manufacturers make it simulate the working mode of SLC, that is, SLC Cache (that is, 3 3bits are used as 1bit). In this way, it brings a small amount of data to read and write, and TLC also has a very fast speed.

When the buffer is full, it will restore the original speed of TLC.

　　It is said to be "temporary solution" because this method can’t keep TLC at a high speed. When the buffer is full, the reading and writing speed will be "exposed".

　　Players need to pay attention to buying mainstream regular manufacturers’ granules when purchasing SSD. The original granules are the best, white films can be considered, and black films should not be considered directly. Don’t be greedy for petty gains. The data is very valuable.

Main control chip

　　The main control chip in SSD can greatly affect its final performance and service life. In addition, the main control chip directly determines whether the SSD of M.2 interface takes SATA channel or PCI-E channel.

　　Main Control Chips Among the mainstream brands in the market, Samsung’s main control chips are often self-produced and sold, and only used in their own SSDs. The main control chips of other major main control manufacturers, such as Marvell, SandForce, Huirong, Qunlian, Zhiwei and Toshiba, are distributed in products of various price segments, and the performance of main control chips of products with different prices is almost the same. The main controller mainly controls the reading and writing of data and FTL layer algorithms (such as wear balance WL, garbage collection GC, etc.), which largely determine the performance of SSD. Players don’t have to worry too much about the specific performance of the main control when purchasing SSD, but they should avoid the "spelling the evening" main control chip:)

Since 2010, the city has implemented the policy of free bus ride for the elderly over 65 years old, and more than 2 million elderly people in the city have enjoyed this benefit. This revision aims at the problems that the elderly in other places can’t ride for free, and the use of the car-respecting card is inconvenient, and further improves the free ride policy for the elderly, making the policy more inclusive and meeting the travel needs of the elderly groups more accurately.

In view of the problem that the elderly people from other places can’t ride free of charge, after the policy adjustment, the elderly people who are registered in this city, those who live in other places in this city and those who come to Tianjin temporarily can enjoy free ride benefits, which further expands the inclusive scope of the policy and implements the relevant provisions on the protection of the rights and interests of the elderly people in the country, so that all elderly people in Tianjin can enjoy free ride benefits.

In view of the inconvenience of using the card for respecting the elderly by car, after the policy adjustment, the elderly registered in this city and the elderly from other places holding the residence permit in this city can choose the third generation social security card, the card for respecting the elderly and the electronic card for riding for free; Old people who come to Tianjin temporarily can apply for a temporary electronic card and a temporary card to ride for free. The richness of free ride media provides a variety of choices and channels for the elderly to better meet the needs of different elderly groups.

In addition, after the policy adjustment, the elderly are encouraged to travel in peak hours and enjoy a safer and more comfortable ride environment, so as to reduce potential safety hazards and relieve the pressure of morning and evening peak rides.

　　The National Day holiday is coming to an end, and the consumer market is booming, showing new characteristics.

　　Wang Bin, deputy director of the Consumption Promotion Department of the Ministry of Commerce, said that this year’s National Day holiday consumption has highlighted four major trends compared with previous years, namely, local consumption, peripheral consumption and home consumption have become new hotspots; Green consumption, smart consumption and healthy consumption are more popular; The demand for personalization and quality has increased, and the heat of high-end consumption has not decreased; Online and offline integration will be accelerated, and the demand for experiential and scene-based consumption will continue to increase. "Consumption will continue to recover steadily in October and even throughout the fourth quarter. It is estimated that the total amount of social zero in the whole year is expected to reach 44 trillion yuan, an increase of about 12.5% over 2020 and an increase of about 8% over 2019. " Wang Bin said.

　　Products with high quality and beautiful price, convenient and fast service and rich individual experience will accelerate the release of consumption potential and foster a more active and stronger consumer market.

　　Buy and produce texture

　　Products are better and services are more intimate.

　　"During the National Day holiday, the sales of flowers increased significantly." The person in charge of the procurement of Box Horse Garden said that decorating life with flowers has become one of the ways for consumers to improve their quality of life. "We stocked a lot of tulips through the Yunnan base before the festival. The first batch of tulips were of high quality and sold well. They were sold as soon as they were listed, and hydrangeas and sunflowers were also very popular." From October 1 ST to 4 th, the sales volume of flowers in Box Horse Garden increased by 290% year-on-year.

　　Ensuring the quality of goods is the most basic demand of consumers. In order to improve the quality, some supermarkets have made more efforts in market research, product procurement and even research and development, and strive to introduce more fine products and "explosions".

　　"This portable tooth washer is selling well at present. The domestic oral care market has grown rapidly, and the oral care products of the public have been upgraded from toothbrushes and dental floss to electric toothbrushes and tooth flushers. " Zhu Lin, general manager of Tmall Personal Care Department, said. The sales of consumption-upgrading products such as cosmetics, electronic products and personal care products in major e-commerce platforms maintained rapid growth.

　　In a Gome store in Haidian District, Beijing, the reporter saw that many consumers came to consult the "old for green" activity. "We jointly launched an activity with air-conditioning companies to replace the air conditioners eliminated in users’ homes with new energy-efficient standard air conditioners, and the number of consumers who went to the store for consultation and purchase during the National Day holiday increased significantly." The relevant person in charge of the store said, "In the past, people paid more attention to the price. In recent years, with the upgrading of consumption, energy-saving, smart and healthy home appliances are more popular. "

　　Zhao Ping, vice president of the China Council for the Promotion of International Trade Research Institute, said: "At present, the pace of upgrading China’s consumption structure is accelerating. On the one hand, commodity consumption is upgrading from low-end to high-end, on the other hand, commodity consumption is also upgrading to service consumption. "

　　Commodities like flowers need merchants to have good fresh-keeping storage conditions, fast logistics and transportation capacity and meticulous after-sales service. "When sent with flowers, there are often detailed maintenance instructions." A consumer who often buys flowers, fruits, seafood and other goods online said that if the quality of the goods is not good, he will immediately apply for a return, and Shangchao often responds quickly and makes a refund or compensation.

　　The relevant person in charge of public comment analyzed the data and found that the service quality played an obvious role in driving the sales of offline businesses. Zhao Ping believes that as China’s consumption scale continues to expand, it is necessary to further improve the supply quality of products and services, organically combine expanding consumption with improving people’s quality of life, promote the creation of a high-quality consumption supply system, and guide enterprises to increase the supply of cost-effective goods and services to better meet the high-end consumer demand of residents.

　　Buy a new experience

　　The scene is richer and the atmosphere is more immersive.

　　Today, online shopping is convenient and fast. Where is the charm of offline shopping?

　　During the National Day holiday, in the National Cultural Industry Demonstration Park of Nanbin Road, Nan ‘an District, Chongqing, the exhibition of the former Art Museum attracted many citizens to visit. "I heard a long time ago that sneakers jointly designed by artists and brands will be exhibited offline here." Liu Zikai, 21, loves collecting sneakers. "We sneaker lovers have been waiting for a long time."

　　Liu Zikai said: "Through the visit, I have a deeper understanding of the design and cultural expression of these shoes. I must buy some pairs to collect at home."

　　In addition to co-branded sneakers, you can also buy masks, scarves and other commodities with the same theme on the spot. Many citizens bought several pieces after watching the exhibition. "If we only sell handicrafts, it will be too far away from ordinary consumers, so we set up a cultural and creative product exhibition area on the first floor." According to the relevant person in charge of the former Art Museum, different from the traditional business model, they have explored in the field of art consumption, and many brands will choose to release their products here because many consumers like unique experiences.

　　At the other end of Nanbin Road, Bainian Old Street just held an autumn and winter clothing conference. "Nowadays, a single consumption environment can no longer meet the needs of customers, and we hope to involve consumers." The person in charge of the event said that in addition to online live broadcast, the site also provided services such as follow-up and styling design. For example, on the day of the event, they invited 10 customers to walk on the catwalk, and Ms. Zhang was one of them. "In the century-old street, wearing fashionable clothes and showing yourself under the rhythm of music and lighting is very special, and some things are still unfinished." Ms. Zhang said.

　　Nan ‘an District, by establishing Nanbin Road National Cultural Industry Demonstration Park, is trying to promote the organic integration of characteristic cultural resources and cultural industries, cultivate new cultural formats and cultural consumption patterns, and build Nanbin Road into a highland for cultural industry transformation and upgrading.

　　"In recent years, experience has become an increasingly important factor for consumers." Mo Yuanming, a researcher at chongqing technology and business university Chengdu-Chongqing Shuangcheng Economic Circle Collaborative Development Center, believes that the market is actively responding to this new demand. Integrated development is becoming a new consumption trend, that is, through the integration of culture and tourism, economy and technology, consumption and culture, to create a brand-new comprehensive consumption carrier. "To promote the development of the retail industry, it is particularly important to shape new consumption scenarios. Through integration and experience, the organic combination of retail, cultural industry and service industry is the essence of shaping new consumption scenes. " Mo Yuanming said.

　　Buy out personalization

　　The demand is more unique and the market is more subdivided.

　　A trendy shop in Zhengjia Square, Guangzhou, Guangdong Province was crowded, and the trend toys with "Chinese style" were placed in the exhibition area, which attracted many guests to stop and take photos. Zeng Qingyuan was one of them. After careful selection, he picked up a cat ornament and prepared to check out. "It’s festive and beautiful, and it’s cool at home."

　　Mr. Lin, who lined up behind Zeng Qingyuan, bought building blocks with children who were in the fifth grade. "Children liked the movie The Wandering Earth before, and now they have the building blocks with this theme, and he immediately took a fancy to it."

　　"We are promoting the Guofeng Building Block Festival, cooperating with domestic designers to design local building blocks, and introducing them to consumers more intensively through the combination of stores and exhibitions." Cai Jianping, the store manager, said that these products were sold out soon after they went online, and many guests made a special trip to ask when to replenish them.

　　Some people like chasing trendy toys, while others like visiting thrift stores. In Chaoyang District, Beijing, Li Bo, a citizen, used his holiday to shop at the limited-time second-hand shop in Sanlitun. Here, you can find second-hand books and many second-hand clothes in various fields. There is also a tailor shop in the shop. "If you find the clothes you like, you can change clothes for free on the spot if it is not suitable." Li Bo said. A consumer said that in addition to meeting the needs of environmental protection, second-hand shops can often bring the pleasure of "treasure hunting", such as finding other people’s reading notes in books, as if they were communicating with the last reader across time and space.

　　Whether it is a trendy shop or a second-hand shop, or a variety of special live broadcast rooms, we can see that the market is showing a segmentation trend in a more colorful state, making it easier for consumers to meet their individual needs.

　　It is worth noting that the emerging new formats and new fields need more in-place supervision.

　　"For example, in the second-hand commodity market, sellers need to provide detailed information. The government or third-party institutions should let consumers know about the purchased goods as much as possible through awards and qualification recognition to ensure the information symmetry of both parties." He Jiang, director of the Institute of International Business of Guangzhou Academy of Social Sciences, believes that in the development of new formats, there may be some problems such as false propaganda and unreasonable service, and because the regulatory authorities are inexperienced in new formats, and these fields are often complicated in terms of objects and contents, it is more difficult to supervise. "Supervision should run through all aspects of production and consumption. On the one hand, improve quality supervision and strengthen the credit system construction of merchants; On the other hand, it is also necessary to establish a post-consumer evaluation system, record and publish consumer feedback in a timely manner, and enhance the convenience of consumers’ rights protection, so that consumers can buy both. " He Jiang said.

　　17.4764 grams of precious samples arrived at 13 scientific research institutions.

　　The lunar soil brought back by Chang ‘e V weighs 1,731 grams, and these "foreign objects" contain too much information and imagination full of science fiction. I believe you still remember this scene on our screen, which was a shocking scene shot by panorama camera after the combination of Chang ‘e V lander and elevator landed at the end of last year — — "High-definition panorama of Chang ‘e landing area on the moon".

　　Now, the lunar soil in the panorama has come to scientists.

　　Now, the first batch of 17.4764 grams of lunar soil samples have been officially handed over to 13 domestic scientific research institutions, and have arrived in Beijing, Hubei, Jiangsu and Guangdong in recent days.

　　From "going to the moon to take soil" to "studying soil separately", that is to say, scientists can finally face the lunar soil at close range. Then, how to divide the precious lunar "native products"? How to use it after "dividing the soil"

　　How to "carefully calculate" lunar soil samples? Counting three highlights

　　The lunar "local products" brought back by Chang ‘e V are so precious that they should be carefully calculated. So, how can it be used well and in what fields will it be used?

　　In this regard, Zhu Rixiang, director of the Moon Sample Expert Committee and academician of the Chinese Academy of Sciences, said that the scientific research on the Chang ‘e V sample will mainly have three highlights:

　　First, have an independent research team.According to experts, in the past, "a clever woman can’t cook without rice". In the past, scientists in China basically couldn’t get Apollo moon samples for research. Now, "there is food in hand, and there is no panic in the heart". Chinese can train its own research team.

　　Second, the Chang ‘e V sample is different from the moon samples obtained by humans in the past, and the sample is "younger".This will have a new understanding of the evolution of the moon and planets and the livability of planets.

　　Third, our goal is the sea of stars.Because new lunar soil samples will be published and distributed as planned in the future, more domestic and foreign scientific research institutions will join the study of lunar samples. Experts also introduced that in the future, Chang ‘e VI will complete the lunar sampling return, and Mars sampling and asteroid sampling have been included in the long-term planning.

　　"Every inch of land is contested": Exploring the micro-composition according to the study of "particles"

　　Yesterday, 500 mg samples of lunar soil powder have arrived at Sun Yat-sen University. In Wuhan, the first batch of 200 mg lunar soil samples also arrived at the School of Earth Sciences of China Geo University (Wuhan). 13 scientific research institutions, and the sample is only a little more than 17 grams, which can be described as"every inch of land is contested".

　　China Geo University (Wuhan) College of Earth SciencesprofessorWang Zaicong:We applied for 200 mg samples this time, and it is estimated that 50 mg samples will be lost, so the lost part may not be returned, and then we will return the remaining 150 mg. For example, some of our work has a certain loss. For example, if we want to get an average composition, we need chemical methods to deal with it. If the sample is destroyed, some samples will be lost.

　　There is water on the moon! ? There may be an answer in the lunar soil.

　　For a long time, scientists have different opinions on whether there is water on the moon or not, and they have never stopped arguing for decades. This time, can you find the answer in the lunar soil sample?

　　On earth, our communication is often affected by solar storms. Since there is no magnetic field on the surface of the moon, how can the solar wind act on the moon? In fact, these can be found in the lunar soil.

　　China news agency, Beijing, December 23 rd: The Central Rural Work Conference set the three major tasks of agriculture and rural areas in 2020.

　　Author Wang Qingkai

　　The year 2020 is the year when China finishes building a well-off society in an all-round way, and it is also a crucial year for rural revitalization. "Well-off society is not well-off, the key is to look at fellow villagers." What is the key to do a good job in agriculture and rural areas in 2020? The Central Rural Work Conference, which closed a few days ago, set three key tasks.

　　Data Map: On October 17, the drone aerial photography took place in Luotian Village, Anyi County, Nanchang City, Jiangxi Province. In the golden autumn season, the rice fields with a bumper harvest were golden. China News Service reporter Liu Zhankun photo

　　Guarantee supply

　　The Central Rural Work Conference proposed that great efforts should be made to do a good job in grain production. Stabilize the sown area of grain and stabilize grain output. Accelerate the resumption of pig production.

　　Ensuring the effective supply of important agricultural products has always been the top priority in the work of agriculture, countryside and farmers. In 2019, China’s grain production reached a record high, with the output reaching 1,327.7 billion Jin, which has stood firm at 1.3 trillion Jin for five consecutive years. In 70 years, China firmly held his job in his own hands.

　　However, the current agricultural development in China is still unbalanced, and the shortcomings such as pork supply need to be filled as soon as possible. In the words of Han Changfu, director of the Central Agricultural Office and Minister of Agriculture and Rural Affairs, although there have been bumper harvests in recent years, the grain production capacity is still unstable. The tendency to relax grain production has risen in some places.

　　The Central Rural Work Conference clearly pointed out that it is necessary to strengthen the assessment of the responsibility system of governors for food security, increase incentives and support for major grain-producing counties, further improve the agricultural subsidy policy, and ensure farmers’ basic income from growing grain.

　　Doing a good job of "agriculture, countryside and farmers" next year will play a "stable role" in the overall economic and social development. Ye Xingqing, director of the Rural Economic Research Department of the State Council Development Research Center, told China News Service that the downward pressure on the domestic economy is increasing and the international situation is changing. It is even more necessary to stabilize the supply of agricultural products and stabilize farmers’ income and consumer markets.

　　Han Changfu said that in 2020, efforts should be made to stabilize the policy and stabilize the area, ensure that the grain area is stable at more than 1.42 billion mu, and the total grain output is stable at more than 1.3 trillion Jin. It is necessary to strengthen the construction of high-standard farmland, do a good job in disaster prevention and mitigation, and continue to adjust and optimize the structure.

　　Guarantee and increase income

　　Ensuring the sustained growth of farmers’ income is the basic requirement of a well-off society in an all-round way, and it is also the potential growth point of China’s economic development.

　　The meeting stressed that it is necessary to develop rural industries that enrich the people and actively encourage all kinds of talents to return to their hometowns for entrepreneurship and innovation. Promote farmers’ sustained income increase through multiple channels.

　　Han Changfu believes that to increase income is to ensure that the momentum of increasing farmers’ income is not weakened and the trend is irreversible, and farmers’ income continues to grow rapidly, and the growth rate continues to maintain "two highs".

　　In the first three quarters of 2019, the median per capita disposable income of rural residents was 10,172 yuan, an increase of 10%. In terms of income growth rate, it continues to maintain "two highs", which is higher than GDP growth rate and urban residents’ income growth rate.

　　The meeting particularly emphasized that it is necessary to stabilize the employment of migrant workers and intensify the rectification of wages owed to migrant workers.

　　Liu Qi, vice president of China Agricultural Economics Association, believes that two aspects should be done to ensure the income of migrant workers. One is to standardize the wage management of migrant workers and ensure that migrant workers and urban workers receive equal pay for equal work; The second is to strictly investigate and punish the behavior of deducting and defaulting on farmers’ wages.

　　"Affected by the macroeconomic situation, the growth rate of the number of migrant workers and wages is facing greater downward pressure." Li Guoxiang, a researcher at the Institute of Rural Development of China Academy of Social Sciences, told the China News Service reporter that it is not easy to maintain "two highs" next year. In the future, we should open up new sources of income and attach importance to the basic role of agricultural and animal husbandry income.

　　poverty alleviation

　　2020 is the year to win the battle against poverty. In Han Changfu’s view, to ensure a well-off society is to resolutely win the battle against poverty, speed up the shortcomings of rural infrastructure and public services, and enable farmers to enter a well-off society simultaneously.

　　The meeting stressed that it is necessary to make concerted efforts to take advantage of the situation and concentrate on fully completing the remaining tasks of poverty alleviation. It is necessary to consolidate the achievements of tackling poverty and prevent returning to poverty, and help the returning poor and the newly poor in a timely manner.

　　"In recent years, the number of people who have reduced poverty every year is tens of millions. The intensity of poverty alleviation is still increasing, and the foundation for poverty alleviation is becoming more and more stable. " Wang Sangui, dean of the China Institute for Poverty Alleviation of Renmin University of China, said that next year, we should focus on areas with deep poverty, such as "three districts and three states", and solve the problem of "two worries and three guarantees" in an all-round way.

　　The Central Rural Work Conference pointed out that the most prominent shortcoming of building a well-off society in an all-round way lies in "agriculture, countryside and farmers". It is necessary to intensify the construction of rural infrastructure.

　　Han Changfu believes that rural infrastructure construction and public services are the most intuitive "gap" of a well-off society in an all-round way and the pain points of farmers’ livelihood. In 2020, efforts should be made to make up for shortcomings. Start the construction project of cold chain logistics facilities for agricultural products storage and preservation, focus on rural drinking water safety, village roads, power and electricity, strengthen the construction of village public infrastructure, and promote the reinforcement of rural education, medical care, social security and other weak links.

　　BEIJING, Beijing, February 9 (Xinhua) According to the weather forecast, strong cold air will be ushered in the central and eastern regions from today, and the temperature drop in some areas can reach 10 ~ 12 C. At present, the annual Spring Festival travel rush is under way, and the meteorological department predicts that the temperature in most parts of the country will be high during the Spring Festival travel rush this year, but the temperature will fluctuate greatly.

　　The central and eastern regions were cooled by strong cold air to 12℃

　　Since the new year, affected by frequent strong air conditioning, the central and eastern regions have continuously encountered a wide range of low-temperature rain and snow weather, and the lowest temperature and snow thickness in many places have set records.

　　Now, the strong cold air is coming again. According to the forecast of the Central Meteorological Observatory, strong cold air will affect the central and eastern regions from the 9th to 11th. At 18: 00 on the 8th, the Central Meteorological Observatory issued a blue warning of cold wave.

　　Affected by strong cold air, from 20: 00 to 11: 00 on the 8th, there were strong winds and cooling weather in most parts of the central and eastern regions from north to south. After cooling, the temperature in the northern region was 2 ~ 4 C lower than normal, and that in the south was 1 ~ 3 C lower.

　　Today and tomorrow, the temperature in northern Sichuan Plateau, northern Gansu, North China, Inner Mongolia, most parts of Northeast China and northern Huanghuai will drop by 6 ~ 8℃, and the temperature drop in some areas will reach 10 ~ 12℃. Most of the above areas have northerly winds of 4 ~ 6, and gusts can reach 7 ~ 8; During this period, the lowest temperature line of 0℃ will be pressed south to the east of Jiangnan to the northeast of Sichuan and the north of Yunnan, and the -10℃ line will be located in the northern part of North China-the eastern part of Northwest China.

　　On Spring Festival travel rush Road, attention should be paid to rainy, snowy and windy weather.

　　Since the opening of Spring Festival travel rush, the cold air coming from the relay has affected people’s way home. According to the monitoring of the Central Meteorological Observatory, in the past 10 days, the cold air activities affecting China were frequent and strong. The average temperature in northern Xinjiang and central and eastern regions was 2 ~ 5℃ lower than normal, and the local temperature in northern Xinjiang and western Gansu was more than 5℃ lower.

　　In addition to cooling, some areas also suffered from heavy snowfall. In the past few days, heavy snowfall has occurred in most areas of Shandong Peninsula, and heavy snow has appeared in Weihai City, Wendeng and Rongcheng. Snowfall once caused hundreds of high-speed toll stations in Shandong to be temporarily closed or restricted.

　　In Beijing, where the passenger flow in Spring Festival travel rush is under great pressure, although there is no obvious rain and snow weather in Beijing this winter, the impact of strong wind cooling on returning tourists can not be ignored.

　　On the afternoon of the 8 th, the Beijing Meteorological Observatory issued a blue warning of strong winds. Due to the influence of strong cold air, it is expected that there will be northerly winds of 4 or 5 in most parts of Beijing from 9 to 11, with gusts of about 7.

　　The impact of weather changes on traffic is obvious. Today is the ninth day of Spring Festival travel rush in 2018. Passengers on their way home should pay attention to the rain and snow information in the next few days.

　　The Central Meteorological Observatory predicts that in the next three days, there will be light snow or sleet in northeastern Tibet, central and western Sichuan, northeastern Yunnan, northwestern Guizhou, central and western Gansu, eastern Inner Mongolia, northern Heilongjiang, eastern Jilin and other places, and local snow or heavy snow; There is light rain in most parts of the south of the Yangtze River and southern China, and moderate to heavy rain in southeastern Tibet.

　　During the period of Spring Festival travel rush, the temperature was generally high, with large fluctuations in cold and warm.

　　From February 1st, 2018, Spring Festival travel rush has been opened. What is the national meteorological situation in the 40-day Spring Festival travel rush exam?

　　According to the forecast previously released by the National Climate Center, the temperature in most parts of the country was high during Spring Festival travel rush this year, but it fluctuated greatly. It is estimated that, except the temperature in the northeast, northeast Inner Mongolia, south China and southwest China is lower than normal, the temperature in other parts of the country is close to normal to high, among which the temperature in the central and western Inner Mongolia, the central part of northwest China, the northwest part of southwest China and Tibet is 1 to 2℃ higher.

　　According to historical statistics, during the period of Spring Festival travel rush this year, it is the transition period between winter and spring, and it is a frequent period of meteorological disasters such as low temperature, rain, snow, freezing, strong wind and smog. The national average temperature is minus 0.6℃, and the average precipitation is 26.1 mm..

　　According to the forecast, during the Spring Festival travel rush this year, there will be more precipitation in the eastern part of Northeast China, the southeastern part of Northwest China, the southern part of Southwest China, northern Xinjiang and western Inner Mongolia, while the precipitation in most other parts of the country will be normal to less, with 20% to 50% less in southern Zhejiang, central and southern Jiangxi, eastern Hunan, Fujian and northern Guangdong, and it is less likely that a large-scale sustained low-temperature rain, snow and ice disaster will occur in the south. In addition, the meteorological conditions of air pollution diffusion are generally poor, including the deviation of air pollution diffusion conditions in Beijing, Tianjin and Hebei and the Yangtze River Delta, and the preference of the Pearl River Delta.

　　According to experts, compared with the same period of the year, the overall impact of weather and climate conditions in Spring Festival travel rush this year is small, but we should pay attention to the impact of staged and local weather. For example, during the period of Spring Festival travel rush, the temperature in the eastern region fluctuated greatly, so it is necessary to guard against the adverse effects of windy and cool weather on traffic and human health.

From the point of view of the real car, the new car is more lovely. The size of the headlights is quite large, and the proportion in the whole front face is not small. The headlights should be internally equipped with lenses and externally equipped with LED daytime running lights, but two and a half rings are used. The charging port is still located in the front of the car, and the whole car looks quite round.

Since its debut, the discussion about Song PLUS DM-i has been endless: the first SUV model equipped with DM-i super hybrid system, and the "dragon beard shape" with the same origin as Han …… With its official listing, its attention has soared again and again, so can Song PLUS DM-i meet the expectations of consumers? Today, let’s have a try.

Wide body and low body lead the trend, and the exclusive design of new energy is well received.

Evaluating an SUV model, high value is definitely a plus item. Song PLUS DM-i extended the design language of Dragon Face 3.0, and the front face design of "Eight-faced Dragons" matched with the rhythmic front grille of lattice scales, which was exquisite and domineering, highlighting the exclusive design of new energy vehicles; The LED light group has been upgraded, the fog light area has a sharp edge shape, and the turn signal is also integrated into the headlights; The wide-body and low-lying styling design and the long wheelbase of 2765mm not only make it the most fashionable SUV in the market, but also the largest SUV in its class. The overall design is closer to the current hot-selling BYD Han DM, which has attracted a crowd before departure.

Entering the car, Song PLUS DM-i adopts the exclusive color scheme of Eclipse Blue+Sky Grey, where blue stands for "technology" and "quietness", and grey highlights "sense of space" and "lightweight". The fresh and elegant color scheme makes people fondle it and feel better. The multi-layer floating design makes the space more natural and clear.

In addition, the Song PLUS DM-i is equipped at the beginning. The whole system comes standard with 12.8-inch 8-core adaptive rotating suspension Pad, mobile phone NFC car key, Dirac 9 speaker intelligent music cockpit, OTA remote upgrade, 360 panoramic image of megapixels, 6 airbags in front and rear rows, VTOL 220V power output and other functions. The high-equipped model of this test drive is also equipped with seat ventilation and heating function. The friends who test drive together sighed, "You can’t go back after using it."

Generally speaking, Song PLUS DM-i not only inherits the outstanding quality of the fuel version, but also creates an exclusive aesthetic feeling of science and technology. It is fashionable in modeling, large in space, cool in sitting and high in configuration, which makes people unforgettable.

Super hybrid strong blessing, the whole test drive "calls" more than

This test drive is the top version of Song PLUS DM-i with a pure battery life of 110KM. It is equipped with three core technologies: Xiaoyun-plug-in special 1.5L high-efficiency engine, EHS electric hybrid system and DM-i super hybrid special power blade battery. The comprehensive power is 173kW, and the whole test process is full of surprises. The multiple advantages of "fast, smooth, static, stable and accurate" are deeply rooted in people’s hearts!

When driving in urban areas, you can feel that the power output of the Song PLUS DM-i is linear and direct, and the throttle response is crisp and neat. When the traffic jam starts, there is no delay, and the power response is comparable to that of pure electric vehicles. When trying to overtake and merge, you can feel generate with a steady stream of power by kicking down. Even high-speed overtaking is fast and steady, so you don’t have to worry about overtaking failure due to lack of power. The accelerated test has answered the doubts, and the actual measurement has reached 7.9s, which is 2-3s faster than that of the same class fuel vehicle. The power experience is completely the level of a 2.0T high-power engine, which is very popular!

During the test drive, thanks to the well-regulated EHS electric hybrid system, the Song PLUS DM-i is super smooth to drive, and there is no sense of frustration in the shift of traditional fuel vehicles at all. The whole vehicle gives people a sense of calmness, and it drives like a pure electric vehicle, which is popular with people!

It is worth mentioning that even if you gallop on the highway with a speed of 100km/h, the noise transmitted into the car is very small, and the communication between the front and rear rows is very smooth, so there is no need to "pull your voice" at all. Song PLUS DM-i adopts double-layer sound insulation and heat insulation glass in the front row and front windshield. Through the acoustic package and seal design of the whole vehicle, it has achieved a high NVH level, which gives people the impression that it is equivalent to bringing its own "noise-reducing headphones" and is quiet in people’s hearts!

With multiple adjustments, the Song PLUS DM-i turns accurately and enjoys stable driving.

Previously, on the high speed, the Song PLUS DM-i felt like a medium-sized SUV, and the chassis had a calm performance. On the way to the test drive, we mistakenly entered a bumpy road, which made us experience the solid chassis adjustment of the Song PLUS DM-i in all directions. Song PLUS DM-i, which was personally operated by German chassis master Hans Kirk, was driving on the potholed road, and the shock was filtered very simply, with almost no unnecessary beating, and the overall performance was still firmly in the hearts of the people!

It is worth mentioning that Song PLUS DM-i has a profound knowledge in handling. The elk test passed the speed of ≥76km/h, and the whole vehicle not only has a small roll, but also has a sensitive and linear brake. In some U-turn sections, the minimum turning radius of 5.55 meters at the same level brings the pleasure of "passing through" and is popular!

In addition, after a long period of congestion, the fuel consumption of Song PLUS DM-i is only 4.6L/100km.

, super mixing is more and more blocked!

It is no exaggeration to say that after five minutes of test drive, you can experience the five extrasensory performances of Song PLUS DM-i, which are fast, smooth, quiet, stable and accurate. In addition, all departments of Song PLUS DM-i can enjoy the preferential policies of exemption from purchase tax and unlimited access to green cards, and have introduced the three-electric lifetime warranty for non-operating vehicles (the first owner) and the six-year or 150,000-kilometer vehicle warranty, which eliminates the worries of car use and further stimulates multiple advantages. In the future, what wonderful story will Song PLUS DM-i write about "the world’s first wide-body super hybrid SUV"? Let’s pay attention together.

On January 26th, Shandong Provincial Department of Transportation held a press conference of Spring Festival travel rush in 2024 to introduce the situation and work arrangement of Spring Festival travel rush in 2024 in Shandong Province.

Spring Festival travel rush officially starts today and ends on March 5th, 15 days before the festival and 25 days after the festival, totaling 40 days. This year’s Spring Festival is the first Spring Festival after the epidemic has turned smoothly. The Spring Festival holiday has been increased from 7 days to 8 days. At the same time, the state also encourages all units to arrange employees to take a break on New Year’s Eve, which can add up to a long holiday of 9 days. Policies to promote the consumption of cultural tourism are being introduced all over the country, and our province will also launch a series of activities such as "friendly shandong New Year’s Celebration". The cultural tourism market is heating up, the masses have a strong desire to travel, and the flow of family visits and tourism will increase substantially. It is expected that the cross-regional personnel flow will reach a record high The Ministry of Transport has made it clear that expressways will be free for 9 days during the Spring Festival holiday. It is estimated that the traffic volume of self-driving passenger cars on expressways in Spring Festival travel rush will exceed 60 million, reaching a record high. The traffic volume of expressways will run at a high level, and the traffic pressure will increase compared with previous years. In terms of passenger flow of traditional commercial transportation, it will reach about 48 million passengers, and it will also be restored to the level before the epidemic, so sufficient transportation capacity has been prepared. However, high-speed rail and civil aviation may still have short-term shortage of transportation capacity in hot routes and hot areas during peak hours. During the period of Spring Festival travel rush, the passenger and cargo flow increased, and the bad weather was prone to occur, so Spring Festival travel rush Baotong was under certain pressure to ensure smooth supply and safe travel.

The 40-day period in Spring Festival travel rush is the period of the largest personnel flow and the most concentrated travel, which is related to the vital interests of the people. The CPC Central Committee, the State Council, the provincial party committee and the provincial government attach great importance to Spring Festival travel rush’s work, and demand that the transportation service guarantee and production safety be well coordinated to ensure the safety, order and warmth of Spring Festival travel rush. In order to do a good job in organizing and guaranteeing the work in Spring Festival travel rush this year, the provincial government established the working mechanism of Spring Festival travel rush in Shandong Province in 2024 to coordinate and organize the work in Spring Festival travel rush. The Provincial Department of Transportation took the lead in formulating the "Work Organization Guarantee Scheme for Spring Festival travel rush in the Province" and supporting measures. On January 24th, the provincial government held a special meeting to emphasize Spring Festival travel rush and the work of safety in production.

Wang Guangpeng, director of the Transportation Management Department of Shandong Provincial Department of Transportation, said that the Provincial Department of Transportation will strengthen coordination and linkage with all members of Spring Festival travel rush’s working mechanism, adhere to the people first and life first, and strive to create a "safe Spring Festival travel rush, convenient Spring Festival travel rush and warm Spring Festival travel rush" to ensure the safe, convenient and comfortable travel of the broad masses of people and ensure the smooth and orderly operation of key production and living materials.

Wang Guangpeng gave a briefing on the preparations for Spring Festival travel rush in 2024:

Improve the travel service experience in Spring Festival travel rush. First, strengthen the optimization of transportation organization.In view of the booming tourism market this year, the transportation capacity of key tourist areas and scenic spots will be increased, and transport enterprises will be guided to operate special tourist lines, through trains and customized passenger transport to meet the travel needs of tourists through multiple channels. High-speed rail and civil aviation will also "run at full speed" to encrypt the number of flights and flights. In addition, rural areas are also places where travelers gather during the Spring Festival, and we will also urge the rural passenger transport capacity to be put into operation.The second is to strengthen the self-driving service guarantee.In view of the strong demand for self-driving travel in Spring Festival travel rush, the Provincial Department of Transportation organized the theme activity of "Warm Way Home" in the expressway service area throughout the province, with the theme of "Happy Service Area Tesco New Year Festival" to create a festive atmosphere, improve service quality and display a civilized image. At the same time, through the highway variable information board, traffic broadcast, WeChat, Weibo and other means, the road conditions and various service information will be updated in time to provide "accompanying" services for the public.The third is to do a good job in travel services for key groups.In-depth development of Spring Festival travel rush’s "full love journey" activities, implementation of Spring Festival travel rush’s voluntary service "Warm Winter Action", organization of volunteers focusing on guidance and consultation, ticketing assistance, civilized travel and the elderly, the disabled, minors and other groups to provide accurate and professional services. For migrant workers returning to their hometowns and returning to work, students will be instructed to carry out "point-to-point" transportation services in a timely manner according to their needs. At the same time, we will fully implement the travel priority policies for military personnel, firefighters and rescuers, and open up a "green channel."The fourth is to improve the transportation connection.Reasonable arrangement of bus and tram, urban rail transit, taxis and other transport capacity and bus stations, railway stations, airports, docks and other transport hubs, to ensure the connection of passengers such as passenger trains, night arrival flights and passenger ships.

Do a good job in safety production in Spring Festival travel rush.Resolutely carry out safety production throughout the whole process and every link of Spring Festival travel rush’s work, so as to ensure people’s safe and healthy travel.First, strengthen the implementation of the Spring Festival travel rush safety responsibility system.In accordance with the requirements of "three management and three musts", strengthen the leadership of local governments, compact the regulatory responsibilities of departments and the main responsibilities of enterprises, pay close attention to the implementation of various preventive measures for production safety in Spring Festival travel rush, strengthen safety training and warning education for all employees, and resolutely build a security line.The second is to strengthen the whole process of investigation and inspection.Thoroughly carry out a thorough investigation of hidden dangers, effectively solve the hidden dangers that affect Spring Festival travel rush’s security before Spring Festival travel rush, and resolutely put an end to the "sick" operation of means of transport and facilities. For 40 days, Spring Festival travel rush continuously carried out investigation and rectification of potential risks and self-examination and spot checks to ensure the safety and order of all links in Spring Festival travel rush.The third is to strengthen the supervision of key areas.The key areas and parts of Spring Festival travel rush will be included in the scope of key control, and measures such as notification, interview, administrative punishment and credit punishment will be fully utilized to implement the whole process of production safety supervision.The fourth is to improve the safety emergency response capability.Strengthen the monitoring of severe weather and establish a mechanism for rapid meteorological notification and linkage response. Strengthen the reserve of emergency transport capacity, emergency personnel, emergency materials and other elements, make emergency plans in various fields, and start emergency response in time for emergencies to avoid large-scale and long-term detention of personnel and vehicles.

Ensure smooth and efficient traffic operation. First, strengthen operation monitoring and unblocking.In advance, carry out investigation on the congested road sections and toll stations in Spring Festival travel rush, formulate diversion and bypass schemes, strengthen dynamic monitoring of road network operation and joint logistics linkage among departments, and ensure the smooth operation of important infrastructure.The second is to strengthen the operation and management of expressways.Supervise the service area to do a good job in service management such as refueling, charging, dining and going to the toilet, so as to ensure adequate supply of goods, clean and tidy environment, convenient and comfortable service and safe and reliable facilities. Strictly implement the free passage policy and the "green passage" policy for small passenger cars on major holidays to avoid long-term and long-distance queuing congestion. Here, I also remind the car owners and friends that the free passage time of the expressway is based on the time when the vehicle leaves the exit toll lane. There is no need to stay at the entrance and wait for the free time to start. If the free time is coming to an end, you can drive out of the expressway nearby and then drive into the expressway to reach your destination. You only need to pay the remaining travel expenses.The third is to ensure the transportation of key materials.We will spare no effort to ensure the efficient operation of trunk transportation, collection and distribution of key materials such as energy, grain, foreign trade and agricultural materials, and do a good job in giving priority and convenient access to transportation vehicles for daily necessities such as vegetables, fruits, meat and poultry, eggs and milk, and guide and support logistics and express delivery enterprises to maintain normal operation during their stay in Spring Festival travel rush to meet the basic delivery service requirements during the Spring Festival.
