Guangdong strengthens the prevention and control of liquidity risk of provident fund, and sets 85% of individual housing loan rate of housing provident fund as the critical point of early warning.

　　On the 28th, the reporter learned from the Guiding Opinions on Early Warning and Management of Liquidity Risk of Housing Provident Fund Funds in Guangdong Province issued by the Provincial Department of Housing and Urban-Rural Development that Guangdong will establish an early warning and management system for liquidity risk of housing provident fund funds.

　　According to the requirements of opinions, through the early warning indicators of individual housing loan rate and net capital flow of housing provident fund, we will comprehensively analyze the capital flow of housing provident fund in time and predict the development trend of supply and demand of housing provident fund loans, and implement early warning in the city as a unit. At the same time, the implementation of early warning classification management. According to the operation of funds and referring to the relevant provisions of the state, 85% of the individual housing loan rate of housing provident fund is set as the critical point of early warning, and it is divided into three early warning levels according to the early warning level: the first warning is that the individual housing loan rate of housing provident fund is between 85% and 90%, and the net flow of funds is negative for three consecutive months; The second warning is that the personal housing loan rate of housing provident fund is between 90% and 95%, and the net flow of funds continues to be negative; The third-level warning is that the personal housing loan rate of housing provident fund is above 95%, and the net flow of funds continues to be negative. When the two early warning indicators of individual housing loan rate and net capital flow meet the conditions at the same time, the corresponding early warning level is triggered.

　　The opinion calls for early warning and management of capital liquidity risk. The Provincial Department of Housing and Urban-Rural Development has established a monthly housing provident fund system through the relevant data of the housing provident fund statistical information system and other relevant data, carried out analysis on the operation of relevant business indicators, monitored the liquidity risk of housing provident fund funds in various cities, and issued early warning risk tips to urban housing provident fund management committees and housing provident fund management centers when necessary. Municipal housing provident fund management centers should establish and improve the liquidity risk prevention and control mechanism, strengthen the research and judgment on the liquidity risk of housing provident fund funds, formulate the implementation plan for the liquidity risk prevention and control of housing provident fund funds, and take corresponding control measures to prevent and control risks according to the early warning level. When the risk warning is triggered, it should be reported to the housing provident fund management Committee and the provincial competent department in time, and corresponding measures can be taken to prevent and control risks.

Have you solved all six math puzzles？ Sorry, I just understood the topic.

Original zzllrr xiaole zzllrr xiaole

Mathematics is really difficult for those who can’t, and it’s not difficult for those who can learn it. It’s not that I consulted Mr. Sun of the decimal newspaper, and finally I got the title of the fourth question. Sweat first! Remembering that many readers have asked the meaning of the riddle, I will explain it briefly together, but I won’t tell the answer, because the date of publication-March 14 has not yet come. Friends who have solved all the questions are also welcome to point a compliment, watch or take a bubble at the end of the article, so there is no need to provide the answer in the message, and give others some opportunities to think independently and enjoy the Eureka moment of solving the math problem. If you feel that solving problems is not enough, being alone is not as good as being happy. Here are some excellent free problem-solving apps for you to enjoy:

Generally speaking, the theme of this year’s International Math Day is Playing with Math (the official translation of classical Chinese is to swim in numbers and feel elegant), which encourages all people, men, women and children to participate. Not only is the topic wordless (breaking the language restrictions of national boundaries), but it is also guided by cleverly designed examples. Think more, relax your mind, don’t think so complicated, and it is easy to guess the meaning of the problem (although the solution may not be necessary)

The first question is Sudoku, with 4 squares (4×4 squares), the purple part on the left is an example, and the title on the right is required. The numbers 1~4 are required to appear only once in each row, column and house (that is, four 2×2 Tian Zige separated by thick lines).

The second question is to use eight eights to construct a formula for four operations (allowing addition, subtraction, multiplication, division and brackets) to make it equal to 1000.

The third question is a stroke problem (the upper part is an example, the lower part is a topic), which requires drawing a path in the graph, passing through each vertex (Hamilton path, which is called Hamiltonian loop when it ends).

Note that a stroke in this question does not require passing through every edge (called Euler path at this time), because it does not meet the conditions of Euler path, and you can’t draw it if you want. If you don’t believe it, you can try.

The fourth question is a guessing game (similar to the character version of the game: Wordle). Combine the numbers on the left and the tips on the right of each line to get the final 3-digit answer.

In each line, according to the different situations of comparing the numbers on the left with the final answer numbers, yellow lights-some numbers are consistent but the positions of the numbers are not, green lights-some numbers are consistent with the corresponding positions, and-dash lines-no numbers are consistent. The number of lights means that several numbers match the corresponding situation.

The fifth question is the specific weight of both ends of the balance scale and the size of the number. Are you online? Fill in the greater than, equal to or less than sign at the question mark.

Question 6 is to fill in the numbers. Fill the numbers from the bottom 1 to 9 in the upper circle respectively, so that the sum of the numbers on each side of the triangle is equal.

Have you answered all six questions? Give it to people around you and try it.

Guangzhou Auto Show Preview ｜ Those models equipped with 4C and 5C rechargeable battery technology

"Charge for five minutes, talk for two hours". In the past, we could only see such a slogan in some mobile phone advertisements. With the continuous progress of battery technology in new energy vehicles, 4C and 5C batteries with "charge for ten minutes and battery life of 400 kilometers" will also meet us soon. As the Guangzhou Auto Show is about to open, this issue will take stock of the new models equipped with 4C and 5C battery technology.

So, what are 4C and 5C batteries? First, let’s find out the meaning of the letter "C". The current value required for the battery to discharge its rated capacity within a specified time can be expressed by the numerical value of the rated capacity (C), which is equal to the multiple of the rated capacity of the battery in data value, and the unit is ampere (A). For example, when the battery capacity of a car is 100Ah, the discharge current of 1C is 100 A; The discharge current of 2C is 200A, so 4C has reached 400A A.. Similarly, high discharge rate also means the improvement of battery charging ability, which is naturally of great concern to consumers. According to the calculation of power = current× voltage, on the basis of 800V high-voltage platform widely used in high-discharge rate battery models, if a battery with a capacity of 100Ah has a discharge rate of 4C, it can input a charging current of 100×4=400A, and then multiply it by 800V, which is the charging power of 320kW per hour. In other words, it only takes ten minutes to charge, and it can charge about 53.3 kWh, which brings considerable power.

Qi Rui Xing Tu Xing Ji Yuan ES: Contemporary Amperex Technology Co., Limited 4C Shenxing Supercharged Battery

"Charging for 10 minutes, battery life for 400 kilometers" in front of the article is the propaganda slogan played by Qixing Road Xingyu Era ES. Based on E0X high-performance electric platform, Star Road Star Era ES is the first China brand car with 800V high-voltage platform for mass production. It is equipped with 4C Shenxing rechargeable battery first launched by Contemporary Amperex Technology Co., Limited, and Contemporary Amperex Technology Co., Limited also characterized it as "the world’s first 4C rechargeable battery made of Ferrous lithium phosphate materials and capable of mass production". Because the positive electrode of the battery is based on Ferrous lithium phosphate material system, the cost of Shenxing 4C rechargeable battery is greatly reduced compared with that of ternary fast rechargeable battery.

Previously, Star Road Star Era ES has started blind subscription, and the blind subscription price range is 260,000-360,000 yuan.

Extreme Krypton 001 FR and Extreme Krypton 007: Contemporary Amperex Technology Co., Limited 4C Kirin Battery

In terms of appearance, the new car adopts a set of sporty encirclement. The front lip, the side lip and the tail wing are all made of carbon fiber, and the hub is also made of high-performance sports tires. From the face value, it is a very strong sports beast. The appearance of extreme Krypton 001 FR has further deepened the sports performance genes of extreme Krypton brand.

In terms of battery, the Krypton 001 FR is equipped with a 100kWh Kirin battery, with a maximum charging rate of 4C, which can charge the battery from 10% to 80% in just 15 minutes.

Although the car Krypton 001 FR is not limited to purchase, it is limited to 99 units per month. If we can’t grab it, we can take a look at the next one.

If Krypton 001 FR is an experimental product of 4C Kirin battery, then Krypton 007, the first car under the Krypton brand, is a sign that Krypton really starts to charge 4C quickly.

As the first medium-sized car owned by Krypton, Krypton 007 is built on PMA2+ platform under SEA architecture, equipped with 800V electrical architecture, Kirin battery, Snapdragon 8295 chip and three laser radars. The news about Krypton 007 is still limited, but with the support of PMA2+ platform and 800V high-voltage electrical architecture, the maximum charging power of Krypton 001 equipped with Kirin 4C battery is expected to reach 400kW.

The price range of the new car is expected to be about 250,000-300,000 yuan, and it will be officially unveiled at the Guangzhou Auto Show, which opened on November 17, and the pre-sale will be started simultaneously.

Wenjie M9: Contemporary Amperex Technology Co., Limited 4C Kirin Battery

On September 25th, 2023, Huawei held a new product launch conference in autumn. Yu Chengdong, chairman of Huawei, announced that the M9, the flagship SUV of Panoramic Wisdom, would be released in December 2023.

The M9 is positioned as a D-class luxury SUV. The length, width and height of the new car are 5230mm×1999mm×1800mm respectively, and the wheelbase is 3110mm.

Hechuang V09: Juwan Technology 4C Fast Charging Battery

Hechuang Automobile is a new energy premium brand jointly invested by Zhujiang Investment Management Group and Guangzhou Automobile Group. It has launched three models: Hechuang 007, Hechuang Z03 and Hechuang A06. On October 13th, Hechuang Automobile’s first pure electric luxury MPV, Hechuang V09, was officially launched and delivered simultaneously. There are five versions of the new car: Deluxe Edition 620, Honor Edition 620, Honor Edition Overcharged Edition 620, Honor Edition 762 and Flagship Edition 762. The standard cruising range of CLTC is 620km and 762km respectively, and the official suggested retail price is 318,800-438,800 yuan.

Hechuang V09 comes standard with 800V high-voltage silicon carbide platform. Among them, Hechuang V09 "Honor Edition Overcharged 620" version is equipped with XFC rechargeable battery customized by Juwan Technology Research. The official said that the peak fast charging power is as high as 410kW, and the charging efficiency has reached 4C level.

Tucki X9: Contemporary Amperex Technology Co., Limited Kirin 4C Battery

Tucki X9 is Xpeng Motors’s new flagship MPV. He Xiaopeng once said that Xpeng Motors will use this model to open the "young" MPV market. Indeed, judging from the design of Tucki X9, the route taken by Tucki X9 is really different from other pure electric luxury MPVs, and the contour lines of the front and rear of the new car are more dynamic.

Coupled with Tucki’s proud advanced intelligent driving and rear wheel steering blessing, it seems that Tucki X9 will focus more on the main driving.

As for the battery, Tucki X9, like Tucki G9 and G6 before, is built by Tucki’s whirlwind architecture, and also adopts 800V high-voltage platform. The battery is ternary lithium-ion battery from Zhongchuang Singapore Airlines. According to speculation, the 4C battery technology provided by Tucki G9 should also appear on Tucki X9, and this 4C battery is still from Kirin 4C battery in Contemporary Amperex Technology Co., Limited. On the 2023 Tucki G9, the Kirin 4C battery appeared as an optional package. On the 2024 Tucki G9, the 4C battery option package disappeared. Generally speaking, whether Tucki X9′ s energy-supplementing efficiency can reach 4C still needs further information.

Zhijie S7: Jiangsu Times Power Battery

On November 9th, the first model of Zhijie brand, which Chery cooperated with Huawei, was officially unveiled and pre-sold. Four versions of Zhijie S7 Pro, Max, Max+ and Max RS were launched, with the pre-sale price starting from 258,000 yuan. It is reported that Zhijie S7 will be officially listed on November 28th.

The length, width and height of Zhijie S7 are 4971mm/1963mm/1474mm respectively, and the wheelbase is 2950 mm. It is positioned as a medium and large-sized pure electric car. The new car is equipped with a new generation of DriveONE 800V silicon carbide power platform and Huawei Turing intelligent chassis. It adopts the combination of front AC asynchronous motor and rear permanent magnet synchronous motor. The total power of the four-wheel drive version is 365kW, the torque is 679N·m, the drag coefficient Cd is only 0.203, and the acceleration of 100 kilometers is only 3.3s s.

As for the battery, no more information is disclosed at present, but the official claims that the overcharged model can increase the cruising range by 200+km after charging for 5 minutes, which has basically reached the charging level of 4C. It is worth mentioning that the power battery pack carried by Zhijie S7 is a mix of lithium ternary battery and lithium iron phosphate battery, and its power battery supplier is Jiangsu Times, which is actually a wholly-owned subsidiary of Contemporary Amperex Technology Co., Limited.

Ideal MEGA: Contemporary Amperex Technology Co., Limited Kirin 5C battery

The ideal first pure electric MPV model-the ideal MEGA is quite hot, and the new car will also be booked at the Guangzhou Auto Show. It can be said that in addition to the appearance of a high-speed train locomotive, the concept of "5C" seems to be the beginning of the ideal MEGA. As the saying goes, "literature is no first, martial arts is no second". When it comes to 5C, people will think of the ideal MEGA first, and this label is even labeled. Of course, the ideal MEGA is not only popular in off the charts, but also has many mysteries. What we can know is that it is expected to be equipped with Contemporary Amperex Technology Co., Limited Kirin 5C battery for the first time, with a peak 5C charging rate, a peak charging current of 700A+ and a peak charging power of 520kW+. The official claim is that it has "brought the fastest charging speed of electric vehicles in the world-charging for 500 kilometers in 12 minutes".

Wubo HT: Haobo 5C Flash Rechargeable Battery

Haobo HT is the third model of Haobo brand. It is positioned as a medium and large pure electric SUV, and it was officially launched on November 15th, with a price of 213,900-329,900 yuan. The new car is built on the pure electric platform of AET3.0 and the electronic and electrical architecture of Spirit. The length, width and height of Haobo HT are 4935x1920x1700mm and the wheelbase is 2935mm, which really gives everyone a big surprise.

In addition, another killer configuration of Haobo HT is that it is equipped with an overcharged battery of up to 5C, which is officially called Haobo 5C flash charging technology. This is a set of closed-loop technology from recharging to battery. It is officially claimed that it can charge for 8 minutes and last for 400+ kilometers, and it will land earlier than the ideal MEGA.

Write at the end:

At the presentation conference of Zhijie S7, Yu Chengdong described the charging of Zhijie S7 as follows: charging for 5 minutes can last for 200+km, and charging for 15 minutes can last for 400+km. Take a closer look, that is to say, the approximate 4C charging power that Zhijie S7 can actually achieve may be 5 minutes in an ideal situation, and the charging power for the next 10 minutes will become 2C; For another example, the charging rate advertised by the ideal MEGA at first was not 5C, but 4C, but after it was changed to 5C, the heat of the ideal MEGA reached the second peak after its appearance was announced.

Higher fast charge rate is naturally the focus of current technical research, but from the consumer’s perspective, the actual experience of recharging is equally important. Only by the long-term word-of-mouth accumulation of users can we know more real feedback. I hope that the fast charging technology of "charging for 10 minutes and cruising for 400 kilometers" can be popularized on a large scale and really change people’s travel life.

Which is the best driving platform？ Which is better, e-driving and Didi driving？

At present, the top ten driving companies are e-driving, Didi driving, hitchhiking, (| |) driving, Ai driving, micro driving, etc. Among them, e-driving and Didi driving are relatively well-known and are also among the best in the driving industry. Many friends who want to join the ranks of driving are hesitant and do not know which driving platform is better. Today we will discuss the situation of e-driving and Didi driving in detail, and give some guidance and suggestions.

Which platform is better?

E-driving status quo: At present, more than 100,000 drivers and 500,000 users have registered, and the business covers 200 cities. It is the first driver platform that has been deployed and entered the market. It has certain advantages in hardware, service system, word-of-mouth and brand. User experience is the hottest, coolest and most practical mobile client side.

Didi driving status quo: a one-stop travel platform including taxis, special cars, express trains, hitchhikers, chauffeurs, and buses. The diversity of services allows more users to choose Didi driving, and it also has many advantages such as driver resources and platform big data, which has won a certain reputation.

Love the status quo of chauffeur driving: China’s chauffeur driving industry is a fast, safe and reliable professional drunk driving service. Starting at 38 yuan is cheaper than a taxi, but it is not as popular as the first two.

Micro Driver Status: It is an application that solves various needs such as drunk driving, business driving, long-distance driving, renting a car, and driving test sparring.

In general, each major driving platform has its own advantages, e-driving and Didi driving have more advantages. Let’s analyze it in detail below.

Which is better, e-driving and Didi-driving?

1. As for how much money Didi and e-driving can earn a month, according to the driver’s report, most of the orders for part-time drivers at night are after ten o’clock in the evening, and one order is more than 100. You can earn about 150 yuan for two or three orders a night, and the driver can earn 2000-3000 yuan a month. No problem.

2. Didi driving and e-driving platforms are a problem. The driver also mentioned that if you drive 10% -20% for a single drive, Didi will have driver points. If the cancellation is greater than 20%, the corresponding points will be deducted (12 points a year), and the e-driving platform will even give the offending driver a ban.

3. Platform scheduling rules. Both platforms adopt the rules of customer self-service or system dispatch. The client side can display the information of the nearest driver. Select one of them or place an order with one click to call the driver for door-to-door service. But the system dispatch requires the customer to place an order on behalf of the driver and make an appointment according to the time of the customer’s appointment.

4. Platform charging standards. Since the charges vary slightly from place to place, in general, the charges for e-driving will be higher. If you want to drive part-time, you can choose e-driving. For details, please click (Didi driving charging standards) or (e driving charging standards) to view.

5. Liability for driving accidents. Didi driving platform liability protection of up to 3 million yuan per order brings greater protection to drivers and passengers when contemporary drivers have accidents. E driving platform liability insurance maximum compensation 2 million.

Cross-border integration has become a trend! NIO mobile phones are coming soon

　　As the concept of interconnection becomes more and more deeply ingrained, representatives from various fields and industries are also using it to cross-border to open up new maps. Take the most common mobile phones entered by automakers as an example. Recently, NIO, one of the representatives of new energy, was revealed that the mobile phone business is ready and will release mobile phones soon. In fact, this is not the first time that NIO’s mobile phone business has been exposed. Before this, NIO co-founder and president Qin Lihong revealed at the event that NIO mobile phones will start internal testing in the second quarter of this year, and it is expected to be officially released to the public in the third quarter of this year. It also announced that it will never hang advertisements in NIO mobile phones, and will resolutely not rely on advertising to make money, which has attracted the attention of the whole industry.

　　Correspondingly, Meizu, a mobile phone manufacturer, has recently made significant moves in the construction of automobiles and smart car ecosystems. For example, FlymeAuto, a new form of smart cockpit based on the Flyme system, has launched three smart car function innovations in the past six months: Smartbar function, small window mode, and holiday desktop function. It has also launched the national co-creation activity "FlymeAuto Master Plan".

(New form of Meizu smart cockpit: FlymeAuto)

　　Due to the popularity of the event participation, a number of high-quality solutions with great feasibility have been born. Take the latest issue of #smarter navigation methods, for example, there are "mobile phones and cockpits are equipped with UWB chips synchronously, and one-click navigation can also be used to find cars in netless scenarios", "HUD and car screen multi-screen interaction, navigation data is kept synchronized", "support for adding multiple pathways, intelligent route planning", etc. I don’t know which of these solutions you are most looking forward to landing?

　　In addition to the "FlymeAuto Master Plan", the recently famous blogger @Garage 42 also revealed the latest progress of Meizu FlymeAuto. Through the information revealed, "FlymeAuto" not only brings "Flyme Link Negative Screen" for mobile phone-car Internet customization, but also the car version of Meizu and QQ Music cooperation has been adapted. Coupled with a split-screen mode with freely adjustable proportions and a "nap mode" with effects similar to 4D/5D movies in scenic spots, it is not difficult to find that the current FlymeAuto is quite mature.

(Part of the function interface of FlymeAuto, picture source: @Garage No. 42)

　　Of course, in addition to the smart cockpit FlymeAuto, the smart phone Meizu, which acts as a carrier, has also invested heavily. Like the Meizu 20 series that will be unveiled recently, the intelligent engine "One Mine 10.0" equipped with the new generation of unbounded ecosystem Flyme 10 will be combined with the second generation of Snapdragon 8 chips to build the unbounded car-connected computing center. Even the unreleased flagships have been laid out. It can be seen that Meizu will have a lot to do on the "stage" of Zhixing this year.

(Meizu 20 series has an unbounded car computing power center)

　　I believe that seeing this, everyone has a new understanding of the construction of Meizu Zhixing ecology, and as the release of Meizu 20 series is getting closer and closer, whether FlymeAuto will finally appear on the same stage is undoubtedly the most worth looking forward to this spring. In addition, it is worth mentioning that the latest warm-up of Meizu 20 series, which has the "Unbounded Car Joint Computing Center", also revealed that the screen will use the suspension dispensing 3.0 process, which can bring a narrow border to 1.57 mm, as well as a visual perception and protection experience of equal width on all sides. For this reason, small partners who have recently purchased a new machine and plan to replace it can also pay attention to this new flagship.

The new owner of BYD Qin plus dmi： Share the 7 advantages and 7 disadvantages summarized by the individual.

Advantages: 1. There are two braking modes, standard and comfortable, corresponding to different crowds, and the comfortable braking distance is long. The measurement of 42 meters of that brake is estimated to be braked in the comfortable mode, and the standard 30 meters is the most. 2. Very fuel-efficient. After all, dmi’s mysterious technology is full of meters with a battery life of 1,200 kilometers. In my case, there are still 900-1,000 kilometers. After calculating, my old car will save at least 500 yuan a month. Some people like to say that dmi’s technology is more expensive, but as a car of hundreds of thousands, what’s the point of your demanding so much?

3. The power is smooth, and the throttle opening and power matching are very accurate. Those who say that they will be frustrated are either the central control setting energy recovery to the maximum, or the accelerator pedal is slammed, or the car is evaluated by the cloud. 4. The dynamic response is very timely, especially at middle and low speeds. This car is actually a commuter artifact. If the acceleration is slower than 100, the fuel consumption and power consumption will rise sharply, but for me, the high speed is 80-100, which is completely enough. 5. There’s a lot of space. I’m 183. I’m sitting in the driver’s seat and I have two fists from the roof. The seat is well adjusted and there is no shortage of space. 6. The reversing image is clear, automatic parking is very practical, and the safety of blind spot detection in rearview mirror is good. 7. The app is very easy to use. In the underground parking garage, the air conditioner can be turned on remotely, and the signal reception is a bit powerful. The 4G card in the central control is free for the first year, and then it seems to be 3-400 years.

Disadvantages: 1. The interior is not exquisite enough, and some places are full of plastic, which is at the same level and quite different from the interior materials of Han. 2. The tire noise is a bit loud, mainly because the engine sound is gone, and the tire sound is particularly obvious. I wonder if it will be better to change the silent tire. But this is after 30,000 kilometers, so we don’t consider changing tires for the time being. 3. When the vehicle starts, it will make a harsh rubbing sound, such as the parking device is not released and rubs against the brake pads. I feel that it is a case. I plan to let the maintenance master do a whole car inspection when I first insure it to see if the brake pads are not properly adjusted. 4. Buying a car is the original price, and there is no discount at all. I can’t even tell the service of the manufacturer clearly, and I didn’t ask for a gift. I booked it on March 4, and waited for 3 months, but I didn’t send a dragon film or a driving recorder.

5. The dashboard is really small and ugly. It is recommended to choose the racing instrument when you buy it, because the racing instrument can be embedded for free, and vice versa. 6. APP sometimes reports errors. Previously, the tire pressure information of the left front tire was not visible, but it can be seen by tire pressure monitoring when you get on the bus. Doubt is a functional problem of the APP. 7. There is a big problem in the back row of space, and the chassis is still not high enough from the ground. After all, the chassis is hung with batteries, so it is very embarrassing to scrape it. To sum up: this car consumes oil, but it takes the circuit. The power has little to do with the engine, but it is related to the output capacity of the power motor. The power battery should provide the power difference between the peak power of the motor and the engine power, leaving a margin of about 30-50kw. If this car is not charged, buying 55 is the best solution. If 120 is matched, pay attention to the installation of electric piles. The distance from the electric meter is 15 meters, and it says 30 meters, but it has to be counted back and forth.

abstract:

Recently, there has been some rebound in the automobile sector. After the rapid market crash in January and February this year, the recent bottom rebound of the automobile ETF (516110) has also reached more than 20%. This also reflects that investors have certain expectations for the recovery of the automobile market. In addition, under the background of the upcoming release of Xiaomi Automobile, the relevant industrial chains, including suppliers of thermal management, air suspension, smart cockpit, interior and exterior accessories, etc., have also been catalyzed to some extent.

In the long run, we feel that we need to pay more attention to two trends: one is the trend of new energy for automobiles, and the other is the trend of intelligent automobiles. In the past two years, the new energy vehicle sector has undergone substantial adjustment, and the main factor is the deterioration of the supply and demand pattern of the industrial chain. However, we have seen that the spot price of lithium carbonate has rebounded from the previous low of 96,000 yuan, and recently reached the level of about 110,000 yuan, which also reflects the improvement of the supply and demand pattern.

From the perspective of automobile sales, the automobile retail market in March was almost at the level of 1.65 million vehicles, up 3.7% year-on-year, and the growth rate also reflected some signs of repair. In addition, it is estimated that the sales volume of new energy vehicles will reach 750,000 in March, up by 37.1% year-on-year and 93% quarter-on-quarter, with a penetration rate of 45%. On the one hand, it reflects that automobile sales have recovered after the off-season during the previous Spring Festival, and the more important reason is that new models were launched intensively in March, including the official delivery of new models and the climbing of production capacity.

In addition, there is still a price war in the current market, which does restrain the sales of automobiles in the short term. However, after the price war of automobiles stabilizes and the price-performance ratio of automobiles is higher, the sales of automobiles will still pick up obviously.

This year, the automobile industry is also facing a major change, and the generative AI is expected to accelerate the upgrade of autonomous driving technology. First of all, the cognitive reasoning ability of generative AI or large model can help the automatic driving algorithm to process and train data sets efficiently, so that the system has the ability of independent data mining and processing, which can improve the efficiency of data processing and reduce the cost. Second, the large model technology can accelerate and help the upgrade and iteration of the autonomous driving algorithm. The third is the simulation system. The large model is expected to build simulation test scenarios related to real driving scenarios, so that the models and technologies of intelligent driving can be trained in these simulation scenarios.

In the long run, the new energy and intelligence of automobiles are still a relatively clear trend. We think we can still focus on the automobile production chain, including some investment opportunities like new energy vehicles and smart cars. From the perspective of investment targets, we can pay attention to such things as automobile ETF(516110), new energy vehicle ETF(159806) and smart vehicle ETF(159889).

Do aquatic dinosaurs exist or not？

　　The prehistoric creatures

　　Intern reporter Dai Xiaopei

　　In the evolutionary history of dinosaurs, one of the biggest mysteries is: Are there aquatic dinosaurs? Although we know that ichthyosaurs, plesiosaurs and canglong all live in water, according to their position on the evolutionary tree, they are not strictly dinosaurs, but only close relatives of dinosaurs. So why are aquatic dinosaurs so rare?

　　Spinosaurus is an atypical aquatic dinosaur?

　　In fact, among the dinosaur fossils found, there are not dinosaurs that did not live in water at all.

　　In 1912, people discovered a kind of theropod dinosaur in Egypt — — Fossils of Spinosaurus, which lived in the Cretaceous period from about 110 million to 93.5 million years ago.

　　According to the early data released by scientists, Spinosaurus was 12.6 to 18 meters long and weighed 7 to 20.9 tons. In recent years, more complete specimens support early research, and scientists found that Spinosaurus could grow to a length of 15 to 15.6 meters. However, the latest data estimate that its weight is 6.4 tons to 7.2 tons. Unlike most dinosaurs, Spinosaurus had some unique spines on its back, forming a sail-like structure. According to public information, the spines on the back of Spinosaurus were at least 1.65 meters long. The spine of Spinosaurus is an extension of its vertebrae, which researchers believe can help Spinosaurus regulate its body temperature or show its unique charm.

　　"After comparing Spinosaurus with crocodiles, people think that Spinosaurus may be aquatic." Xu Xing, a paleontologist at the Institute of Vertebrate Paleontology and Paleoanthropology of China Academy of Sciences, told the Science and Technology Daily reporter that according to the skull shape of Spinosaurus, it was found that the skull of Spinosaurus was long and narrow, similar to that of modern crocodiles. Specifically, the mouth is slender, and the direction and size of teeth help it catch fish and fix its prey in the mouth.

　　In addition, by analyzing the fossils of individual Spinosaurus, some scientists found that there were fish scale residues in the stomach contents of Spinosaurus. "This shows that Spinosaurus ate creatures in the water, and it can be speculated that Spinosaurus may live on the shore or in the water." Xu Xing said that another evidence that Spinosaurus lived in water is that studies have found that the isotopic composition of Spinosaurus bones is close to that of aquatic animals.

　　However, Xu Xing stressed that there is no very conclusive evidence that Spinosaurus must have lived in water. "Because Spinosaurus didn’t have a fin-like structure like aquatic animals such as sea lions or seals. This shows that Spinosaurus cannot live completely in water and is not a typical aquatic animal. " He said that according to the existing findings, it is not easy to judge whether Spinosaurus lived in the water or on the shore for a long time.

　　"According to the teeth and skull of Spinosaurus, people think that Spinosaurus mainly lived by eating fish, but Spinosaurus is just a kind of dinosaur with a special feeding habit, and generally speaking, Spinosaurus just goes into the water to prey and then returns to land life. Therefore, we cannot put forward ‘ Aquatic dinosaur ’ The concept. " Xing Lida, an associate professor at China Geo University, said.

　　Dinosaurs were aquatic animals?

　　Some scientists believe that dinosaurs were originally aquatic animals. This statement stems from a puzzle: how did the slender legs of dinosaurs support its huge body? Brian Ford, a cell biologist at Cambridge University in England, tried to explain that dinosaurs mainly lived in water and supported their bodies by buoyancy. He said that dinosaurs swam in the lake most of the time, and their tails provided assistance, and their footprints were printed into the mud.

　　According to Ford, it can explain why archaeologists often dig dinosaur footprints, but there are few traces of dinosaur tails. Compared with modern large animals such as elephants and rhinoceroses, dinosaurs had small legs but fat tails.

　　"It makes sense to think that dinosaurs lived in water." Ford said, "dinosaurs used water to support their weight, float their tails, regulate their body temperature and get food."

　　However, Paul Barrett, a paleontologist at the Natural History Museum in London, believes that this statement makes no sense. He said that with the help of the principle of load-bearing structural engineering, researchers have proved that the strength of dinosaur leg muscles is enough to support its body to walk easily on land. Moreover, dinosaurs had difficulty breathing and walked slowly in the water. "They may live near water, and sometimes they go into the water to cool off, but I don’t accept the theory that they live in water." Paul said.

　　In 2007, scientists found traces of dinosaurs’ claws at the bottom of the water in the Carmelos basin in northeastern Spain, which became conclusive evidence that "dinosaurs could swim". In 2011, Chinese and American paleontologists found a group of strange footprints with only toe marks and no heels in Chicheng County, Hebei Province. Experts believe that this is the hard evidence of dinosaurs playing in the water — — Tracers leave scratches on the bottom of the lake after entering the water. As the depth of the lake increases, their feet can touch less and less water bottom, and their footprints gradually weaken, and their three toes can not be completely preserved.

　　Completely aquatic dinosaurs don’t exist?

　　Although there is evidence that some dinosaurs lived in water, Xing Lida still opposed the concept of "aquatic dinosaurs". “‘ Aquatic dinosaur ’ It is only a hypothesis put forward in recent years, but it is extremely easy to include Syngnathus, Canglong, plesiosaur, etc., confusing concepts. "

　　Xu Xing also told reporters: "According to the existing research, there are no pure water dinosaurs. Let’s just say that there is some evidence that dinosaurs lived in water for some time. The limbs of plesiosaurs, ichthyosaurs or sea lions and seals will undergo height changes to adapt to life completely in water, but there is no evidence that such dinosaurs exist at present. "

　　Strictly speaking, no real aquatic dinosaurs have been found. Xu Xing believes that there are two possibilities. First, dinosaurs did not give priority to occupy the water niche in the era when they lived. At that time, the water environment might be occupied by crocodiles and other aquatic animals. Second, there may be aquatic dinosaurs, but they have not become mainstream species, and the fossils of such dinosaurs have not been preserved or discovered.

　　"In recent years, with the deepening of field trips, people have discovered more and more strange dinosaurs. The current fossil record has not fully revealed the diversity of dinosaurs. " Xu Xing said that the original fossil record is deficient, some deficiencies may be remedied, and some deficiencies may exist forever.

　　What’s the point of studying dinosaurs and even arguing about whether dinosaurs were aquatic or terrestrial?

　　"First of all, it can prove some evolutionary phenomena. Species are always changing, such as from big to small, from land to air. Scientists hope to reveal the law of change. " Xu Xing said that the current ecosystem is called the world of birds and flowers, characterized by beautiful birds and flowering plants, and this ecosystem evolved from the Mesozoic ecosystem dominated by dinosaurs. We need a lot of data and fossil records to reveal this evolution process.

　　At the same time, scientists should also reveal which factors affect the evolution of life, such as genes or environment. "It is also important for human beings to understand their own lives to understand the laws of the evolution of all things." Xu Xing said.

　　This dinosaur can also swim and hunt in the water.

　　At the end of 2017, research teams from Italy and other countries discovered a new dinosaur fossil in the late Cretaceous strata of Mongolia, which was roughly waterfowl-like. This new dinosaur species was named Eichzka, commonly known as "duck dinosaur". "Duck Dinosaur" has a long and curved neck, and its forelimbs are fin-shaped. It can walk on land like a duck and swim with its forelimbs. They also have many tiny teeth suitable for eating fish. Another feature of "Duck Dinosaur" is that its beak and upper jaw have many small holes, which were once filled with nerve endings. This kind of mouth has a similar structure to the beaks of some waterfowl. This shows that "duck dinosaurs" may have preyed in the water or at the bottom of rivers and lakes.
