AI pathologist is here! "Working speed" is 10 times that of manual work.

  As soon as the AI pathologist came out, he refreshed the highest level of AI-assisted cervical cancer screening at home and abroad that has been published internationally!

  On the basis that the negative rate is higher than 60%, the correct rate of negative interpretation of cervical smear is higher than 99%, and the detection rate of positive lesions is over 99.9%. Cytopathologists read cervical smear under microscope, which takes an average of 6 minutes per case, while AI identification takes only 36 seconds. The interpretation speed of AI-assisted cervical cancer screening model is 10 times that of manual interpretation!

  The all-media reporter of Guangzhou Daily learned from the release conference of artificial intelligence-assisted cervical cancer screening in China Bio-industry Conference that Jinyu Medicine and Huawei technology have made a breakthrough together. Based on pathomorphology, the teams of both sides trained an accurate and efficient AI-assisted cervical cancer screening model with the diagnostic criteria of pathologists for the first time through deep learning technology.

  Text/Guangzhou Daily All-Media Reporter He Xuehua Correspondent Zhang Jinju

  Pathology is the gold standard of diagnosis, but there are too few pathologists.

  Pathomorphological diagnosis is recognized by the medical community as the "gold standard" for disease diagnosis.

  Dr. Liang Xiaoman, a well-known cytologist in China, has been engaged in clinical cytological diagnosis in the Cancer Hospital of Sun Yat-sen University of Medical Sciences for decades. He pointed out that the body has pathological changes. What exactly does it mean? Benign or malignant? What is the degree? Diagnosis depends on different morphological changes of pathology.

  However, only 5,000 cells are qualified for a pathological glass slide, and there are tens of thousands of cells. If pathologists look at it one by one, it will be exhausting and very boring to look at 100 pieces a day. Therefore, a "pathological person" sees 90% negative films every day, and gets excited when he sees positive films. "It’s really not easy to see people get excited when they are sick," said Liang Xiaoman. This is a double high effort of brain power and physical strength.

  There is a great demand for pathological diagnosis, but there is a shortage of pathologists.

  Liang Xiaoman said, for example, like cervical cancer screening, cytology should be combined with HPV testing. In China, there are more than 350 million school-age women aged 25-65, and screening once every 3-5 years requires 70 million people to be screened every year. But in fact, since 2009, women’s screening for two cancers has been promoted, and the total number of cervical cancer screening in 10 years is only a little over 70 million, that is, the population coverage rate is only 21.4%.

  Medical research shows that the population coverage rate of screening should reach 80% in order to reduce the incidence of diseases in the population.

  The lack of disease screening ability lies in the long-term scarcity of pathologists in China. Reading films under traditional microscope needs to be based on human visual interpretation, knowledge accumulation, skills and talents, and the training period can often be as long as 10 years. The data shows that there are currently less than 20,000 registered pathologists in China, and the gap is still as high as 80,000-100,000 based on the standard of 1-2 pathologists per 100 beds.

  AI-assisted cervical cancer screening made a major breakthrough

  "So, I am very excited to hear that AI pathologists have made a breakthrough in research and development!" Liang Xiaoman said that it was initially seen that "this AI pathologist" can reduce the workload of manual interpretation by about half, which means that the other half of labor and energy can be devoted to improving the positive rate interpretation, and the chances of pathologists being complained of "seeing less, not seeing correctly and seeing slowly" will also be greatly reduced.

  The AI pathologist mentioned by Liang Xiaoman refers to the AI-assisted cervical cancer screening model jointly developed by Jinyu Medical and Huawei Cloud.

  There are about 500,000 new cases of cervical cancer in the world every year, and the incidence rate in China accounts for 26%. As long as the disease of cervical cancer is screened and treated early, its cure rate and five-year survival rate can be greatly improved.

  According to reports, this development is based on 43.5 million cervical cytology screening samples over the years, and nearly 200,000 image blocks are selected for accurate labeling and AI-assisted screening model training.

  First of all, it is marked by many pathologists to ensure that the model can fully learn the morphology of various pathological cells. Based on the block-level labeling of these images, the AI model first classifies the samples and efficiently distinguishes the samples with high positive cell density.

  Then, the AI model further accurately identifies positive cells to ensure that accurate auxiliary interpretation results can still be obtained on samples with low positive cell density. In order to ensure the correct results, the algorithm also selects a series of suspicious local visual fields and submits them to the pathologist for final review.

  At present, the AI model has been verified with the verification set of more than 20,000 sample data. The verification results show that the negative rate of the model is 61.9%, the accuracy of negative film interpretation is higher than 99%, and the detection rate of positive lesions is over 99.9%. This is the highest level of AI-assisted cervical cancer screening at home and abroad.

  Application of results:

  There are at least three to five years before landing.

  The development of AI pathologists can be described as an important practice of digital medicine and precision medicine, which provides strong support for accurate diagnosis in the future. Once the results are applied, it is expected that the workload of single cytological examination by pathologists will be reduced by more than 60%, and the screening efficiency will be greatly improved. Usually, it takes 6 minutes for cytopathologists to read cervical smear under microscope. The AI ? ? recognition takes only 36 seconds, and the interpretation speed is 10 times that of manual interpretation.

  At the same time, by comparing and verifying the results of AI tips, doctors can make manual interpretation more conveniently and accurately, which can bring effective help to the quality control of pathological examination and the training of pathological students.

  In terms of greater social benefits, in the future, once AI-assisted cervical cancer screening is applied and promoted, it will greatly improve the coverage and service frequency of cervical cancer screening services, so that the screening quality of school-age women can approach the level of developed countries and promote early screening and early treatment of cervical cancer.

  However, experts also admit that the results are at least three to five years away from landing.

  First of all, we should continue to invest more sample data to verify the AI model on a large scale, and at the same time make more professional annotations to improve the model, so that its specificity will be continuously improved under the premise of ensuring sensitivity, and even adapt to and be close to the reagent consumables and production level of primary hospitals.

  Secondly, it is ready to start the registration of CFDA. It is understood that there is no clear guiding process and cycle at present. "Many analysts in the industry believe that the large-scale application of medical AI such as pathological AI and imaging AI in China is estimated to take 3 to 5 years."

  "AI pathology" vs "AI image" is more accurate.

  In recent years, AI medical care has become more and more hot, which belongs to the field of auxiliary diagnosis. AI images have developed even faster and entered the registration application process earlier than AI pathology. So, which is stronger, AI pathology or AI image?

  In this regard, some cytopathologists believe that AI pathology is "more difficult, more refined, more lacking and slower".

  Because the image is based on black and white, density, size and edge, and the pathology is polychromatic and reaches the cellular level, it is not just an auxiliary diagnosis of "whether it is a tumor" or "whether it is a lesion".

  In other words, AI imaging doctors can "allow" the conclusion that "this may be a cancer, a benign tumor or a malignant tumor", while AI pathologists can’t do this, but tell "what is this, is it a cancer, and what kind of cancer it is".

Taking Meituan Takeaway as an Example: Disassembly Transaction Model and Decision-making Trade-offs

Trading model is a key point that must be considered in product operation and profit. For products in the information age, the transaction between roles is not limited to the cost of money, and attention is also one of the goals that products compete for, so the generalized transaction also includes time cost and emotional cost. In a complex trading model, how to balance the value-interest relationship of all parties is a key factor for the long-term survival and sustainable development of a product.

In this paper, we will take Meituan Takeaway as an example to accomplish two tasks:

  1. Disassemble the transaction model of the whole process from ordering, delivery to refund;
  2. Taking the user’s modification of delivery address as an example, this paper analyzes the decision-making trade-off.

In the transaction model, the first thing to consider is the multilateral role in product transaction and its interrelated relationship. In the simple model, the identity role can be expressed by points, and the directional relationship can be expressed by lines and arrows. The direction of the general arrow is the flow direction of interests. The more identities of users of a product, the more complex the model is, and it is spread out in a network.

Order circulation refers to a series of processes from user placing an order, merchant receiving an order, rider delivering to order completion. In the whole process, there are four key roles involved, namely, users, merchants, platforms and riders. Among them, the riders of the US group take-out can be divided into four categories: special delivery by the US group, express delivery by the US group, running errands by the US group, and merchant delivery (the first two belong to platform management, running errands belongs to third-party services, and merchant delivery belongs to self-delivery), which are collectively referred to as the rider’s side here without distinction.

In the transaction model of order flow, there are user-platform, platform-merchant, merchant-rider, which can be represented by the following figure:

From the user’s point of view, order cancellation can occur in three time periods: before delivery, during delivery and after delivery. Among them, before the order is sent, the role involved is user-platform, and two situations will happen.

1) The user cancels the order within 1 minute before or after the order is confirmed, and the platform directly cancels the order;

2) If the order submitted by the user is not confirmed within 5 minutes, the platform will automatically cancel the order.

After the order is delivered, the refund process involves the user-merchant, and there are two corresponding refund situations.

1) If the special delivery order of Meituan is not delivered for more than 30 minutes, the user applies for a refund, and the platform automatically agrees to the refund and cancels the order;

2) The user applies for a refund, and the merchant handles the refund.

The trading model is as follows:

In the take-away platform, because of the multilateral relationship between users, merchants, riders and platforms, disputes and contradictions often arise, such as complaints from users about merchants’ dishes and complaints from riders about merchants’ slow delivery. Because such problems involve many parties, it is the key point to determine the responsible party.

In the takeaway scene, users often encounter the problem of changing the destination. Can the platform allow users to modify the destination, and can merchants or riders refuse to modify the destination? The difficulty of this problem lies in the roles involved in the different processes of the order.

The process of order circulation can be divided into several situations: the user has placed an order but the merchant has not received it, the merchant has received the order but has not delivered it, the rider has received the order but has not delivered it, the rider is delivering it and the order has been delivered. This part will reflect the influence of the judgment of the responsible party on the platform from this example.

After the user places an order, the take-away system will register the order first, and then push the order to the merchant. Sometimes, because the store is busy or there is a lack of manpower in front of the system, there is no answer to the order. If the push is unsuccessful, the system will push the order again every 1 minute until the order is automatically cancelled for 3 times.

In this process, no merchants or riders have entered the order, and the responsible parties involved are users and platforms. If the user wants to modify the destination, he can directly cancel the order and re-place the order or wait for the merchant to take the order before changing the destination.

Re-ordering will not have any impact on the system of pushing orders, and users are willing to pay extra time costs for re-ordering and waiting for orders. However, what users care about is whether the vouchers, red envelopes and allowances paid for the order can be returned with the cancellation of the order and then used in the next order.

Here, we need to consider two kinds of benefits provided by the platform and set by the merchant. Should both benefits be returned to the original account with the cancellation of the order? If returned, the user pays a simple time cost problem; If you don’t return it, will it affect the user’s willingness to place an order with the same merchant or use alternative takeaway software to complete the order with the same merchant?

After the user places an order, the delivery address is linked to the expected delivery time, which will be sent to the merchant through the system. After the merchant confirms the order, it will enter the takeaway production. In this state, the responsible party involves the merchants.

From the merchant’s point of view, there will be great resentment against the user’s desire to modify the address, especially if the distance becomes longer after changing the address, the delivery time will be later than expected, and the merchant will worry about the follow-up reminders, complaints and evaluation problems.

In addition, the attitude of the merchants also depends on whether they choose the US group delivery or self-delivery. In the case of delivery by Meituan, its delivery mechanism will consider whether it is on the way, the distance, the delivery time and other issues. Changing the address will affect these factors at the same time, and then the rider assigned to this order will be different, but the merchant is only a receiver.

However, in the case of self-delivery, the merchants are also responsible for the subsequent delivery, and their dissatisfaction is far greater than that of Meituan delivery, because when the original order was received, the merchants would prefer short-distance orders and along-the-way orders, and the modification distance would not only affect the delivery of this order, but also affect the delivery time of other orders.

What is discussed here is only the automatic distribution of delivery orders after accessing the Meituan system. When users can’t contact the riders directly, they will contact the riders through the merchants, and the power and responsibility parties involve users, merchants and riders.

Under the delivery managed by the US Mission, the rider passively accepts the order, and modifying the destination may cause a decrease in the number of orders on the way, but the same probability is that there are not many orders on the way at the original address, so the impact of modifying the address on the special delivery rider is not great.

However, for crowdsourcing riders, orders are grabbed, and the closer the distance is, the more orders there are along the road, the easier it is to grab, while the delivery fee will increase relatively for orders with high long-distance time cost, but the rider’s willingness to deliver is low.

The habit of crowdsourcing riders is to take orders all the way along the road and get the relative maximum benefit at a certain time cost. When modifying the destination, crowdsourcing riders are much more disgusted than special riders, because in the case of changing the distance, the established delivery fee will not change, the time cost will increase, and the orders along the way will decrease, which will greatly reduce the maximum income that could have been obtained.

Compared with the previous situation, the loss of opportunity cost of the order that the rider has already delivered is greater. The rider should not only bear the time loss spent on the journey of this order, but also bear the time loss of other orders that have been taken by the way and the loss of potential order opportunities.

Considering the extreme situation, the user’s modified delivery address and the original address are in opposite directions. In the process of value measurement, will the rider risk being complained to give up this half-way order to ensure the delivery of other orders, or will he reach this order within the delivery time to avoid complaints and click to confirm the delivery in advance? If the delivery fee of the modified order far exceeds the cost of the original order, will the rider give up the original order?

From the perspective of platform guidance, if the punishment mechanism is blindly guided by the service concept and follows the principle of user > rider, will it lead to frequent phenomena that users modify the delivery address, riders abandon orders or click to confirm delivery in advance? Should the complained rider take full responsibility, thus discouraging the rider’s enthusiasm? If the punishment mechanism is humanized, can it make the rider make a choice faster without the fault? Simply applying the principle of user first to deal with all conflicts of interest will not only "spoil" users, but also be detrimental to cultivating riders’ emotional dependence on the platform.

After the order has been delivered, the user finds out that his delivery address is wrong. Who are the responsible parties in this case? This involves the question of who will confirm the completion of the order after it is delivered. There are three options for the takeaway platform, namely, the rider, the user and the platform to confirm the delivery.

First, after the rider confirms the delivery, it is not necessary for the user to confirm whether the address is delivered correctly. The user wants to modify the destination again, and the rider has no obligation to deliver it to the modified address again. In this way, the user’s dissatisfaction is high, the user experience is poor, and even the order will be refunded and the rider will be complained.

On the one hand, whether the order can be delivered again can only be supported by the professional ethics that the rider can’t quantify, on the other hand, it depends on whether the merchant cares about quantitative indicators such as rating and return rate, and the constrained merchant may spontaneously bear the loss of this order and re-dispatch the order.

Second, after the user confirms the delivery, the rider only needs to send the order to the designated address, but the user needs to pay the cost of reconfirmation. Judging from the ordering process of users, users habitually enter the dining process directly after receiving the delivery call, instead of entering the delivery platform again to complete the last step, so the pressure of unconfirmed delivery is transferred to the rider.

The user who has the right to receive goods wants to modify the delivery address, which is entirely in a favorable position, because the rider can’t get the commission if the order is not completed, and the rider doesn’t deliver it again according to the user’s requirements, which not only bears the cost of the previous delivery, but also suffers from the punishment of the platform.

Third, under the platform confirmation, there are several situations. One is that after both the rider and the user confirm the delivery, the platform completes the confirmation after this match; The other is that the rider confirms the delivery. Although the user does not click the confirmation within the specified time, the platform defaults to the user’s choice of delivery. The former is similar to the second case, while the latter is that the platform becomes the responsible party.

The user passively confirms without knowing it, and wants to modify the address and find the merchant or rider. Although both of them have to bear the risk of bad reviews, the degree of fault is far less than that of the platform, so the platform is likely to be used as a bullet. At this time, the platform will bear the money and reputation loss of returning the order.

For orders with different delivery status, if users want to modify the delivery address, Meituan’s strategy is as follows:

(1) For take-out orders without orders, it is supported to place orders again after returning the orders.Red envelopes used during payment within the validity period will be returned within 24 hours.

Problems you will encounter: Re-placing an order immediately after the cancellation of the order may lead to a reduction in the discount if the red envelope has not been returned, so that the loss of users from this business or to other platforms cannot be ruled out.

(2) For take-away orders,There are two ways to deal with the US group’s takeaway suggestions:

  • Meituan delivery supports online modification of delivery address.
  • Merchants are self-equipped, so it is recommended to contact merchants or riders to communicate.

For the former, most riders take the attitude of delivering the order first, and then they can report the abnormality and complaint to the order.

Problems encountered: If the user complains about the order, the rider will also encounter the situation that the money deducted cannot be recovered if the complaint is not passed.

In the punishment mechanism, if the user complains that the delivery time exceeds the expected delivery time and the goods are not received, or the actual delivery time exceeds the expected delivery time, the self-made merchants need to bear the full refund responsibility, that is to say, for the latter, the merchants can only swallow their own bitterness.

If the experience of riders is not good, they will be lost. However, in the current environment, the supply of riders in first-and second-tier cities is far greater than the demand, so the loss of riders will not increase the cost of distribution, and the old people will make up for it immediately.

What the platform really lacks is users. When choosing which platform to place an order on and which merchant to place an order on, users always have the initiative, including modifying the address, and merchants and riders revolve around users. Therefore, it can be said that the tripartite experience of merchants, riders and users has not yet reached a level of common satisfaction.

How to "eat" resistance? Nutrition expert: three meals a day, four kinds of food.

  BEIJING, Beijing, Feb. 23 (Reporter Sun Zifa) On Feb. 23, the lunar calendar has entered the Year of the Rat in February, and the "epidemic" of the whole country has continued for more than a month. At the moment of epidemic situation, it is very important for the public to do personal protection, improve their own resistance and strengthen their immunity.

  As the saying goes, people are iron rice and steel. What is the connection between diet and immunity? During the "epidemic" war, how to enhance the body’s immunity through diet? What problems should be paid attention to in diet? Chief physician Chen Wei, chairman of the Clinical Nutrition Branch of China Nutrition Society and deputy director of the Clinical Nutrition Department of China Academy of Medical Sciences/Peking Union Medical College Hospital, responded one by one through the online interview organized by China Association for Science and Technology, stressing that three meals a day should be kept healthy, four kinds of food should be guaranteed every day, more than 12 kinds of food should be guaranteed every day, and at least 25 kinds of food should be eaten every week.

  Professor Bo Huang, vice chairman of the Chinese Society of Immunology and the Department of Immunology of China Academy of Medical Sciences/Peking Union Medical College, also pointed out that a healthy and reasonable diet is undoubtedly the basis for maintaining the normal function of the whole cell. In the face of the current epidemic situation, eating more foods such as mushrooms, Lycium barbarum, Ganoderma lucidum powder and auricularia auricula is helpful to improve immunity, because these foods are rich in plant polysaccharides, including lentinan, Lycium barbarum polysaccharide and Ganoderma lucidum polysaccharide, which can stimulate receptor molecules on the surface of natural immune cells and make immune cells in a pre-stimulated state.

  What is the relationship between diet and immunity?

  Chen Wei said that the human body has three layers of "defense walls" to resist external invasion. The first layer is skin and mucous membranes on the surface of the body, through which more than 90% of viruses and bacteria are attacked by the outside world. If the virus enters the body, the body will start the second layer of protection, which can kill most foreign viruses and germs by secreting mucus and phagocytizing cells through the mucosa; If it is unfortunate that some viruses enter the body or even cells, the third layer of human protection will start, and antibodies will be produced by intracellular substances, and the invading viruses will be removed through antibodies. Therefore, these three lines of defense determine the vast majority of people’s immune functions.

  Are these three layers of defense related to diet? Chen Wei pointed out that the mucus secreted by mucous membranes mentioned above and the antibodies produced by human own cells are all protein, and these protein forms the basis of the body’s resistance. "Where does protein come from? You have to eat to come. Unlike plants, the human body needs light for photosynthesis, and the human body must rely on our mouth to eat nutrients and eat our resistance. "

  How to "eat" immunity?

  Since diet is closely related to resistance, how to improve resistance and enhance immunity through diet? Chen Wei gave the answer with a set of data:

  First, keep healthy three meals a day. During the epidemic, many people are forced to stay at home and keep a regular life. In addition to normal sleep, they must eat three meals to maintain their resistance, and they must not reduce their meals, including breakfast, lunch and dinner. Second, four kinds of food should be guaranteed every day, including grains (sweet potatoes), vegetables and fruits, high-quality protein foods and oils; The third is to ensure more than 12 kinds of food every day, that is, there must be at least 12 kinds of food in the four categories; Fourth, eat at least 25 kinds of food a week to achieve a more balanced nutrition and enhance resistance.

  He also provided specific recipes, saying that grains (sweet potatoes) should eat at least three or more staple foods and no more than one kilogram every day, with flour and rice or coarse grains, including rice, white flour and other ingredients, and some sweet potatoes like sweet potatoes, yams, taro, potatoes and other ingredients; Vegetables and fruits should eat 1-2 kg every day to supplement vitamins and dietary fiber to meet the basic needs of nutrition; High-quality protein foods "should eat good things in place", including meat, eggs, milk and bean products. Among them, at least 2-3 pieces of meat, 1-2 eggs, 1-2 bags of milk and a little tofu every day constitute a high-quality protein combination; Oil should be protected with a little oil, 2-3 spoonfuls of oil every day.

  What should you pay attention to during the epidemic?

  Chen Wei first clarified the rumor that "eating garlic can prevent viruses" and "rubbing sesame oil can fight germs" and other foods to treat COVID-19. He pointed out that the impact of food on immunity only refers to the basic role, and there is no special food, and folk remedies can’t cure diseases, nor can they really prevent diseases. "Eating a good meal, doing exercise and doing personal protection are the most important and effective ways to get through the epidemic safely".

  He said that during the epidemic period, the public’s attention in diet also included sharing meals, cooking food thoroughly, not superstitious about refrigerators and balconies, and staying away from wild animals.

  In the dining system, everyone will be very careful when going out or in public, but they will often relax when they get home. We should pay attention to this. We should reduce family dinners, and three people should eat their own meals. If there are public dishes, we must try our best to use public spoons and chopsticks to reduce cross-correlation.

  When cooking food, we must pay attention to cooking the food thoroughly. Chen Wei suggested heating it for one minute more than usual during the epidemic. "It is cooked, cook it for one more minute and stew it for one more minute, which is safe for you and your family life."

  It’s still winter, and some people in the north want to put food such as fruits and vegetables on the balcony, which can’t be cold outside, or put it in the refrigerator, which can freeze the germs to death. Chen Wei pointed out that those who have this idea must pay attention to the fact that refrigerators and balconies can only provide a certain storage temperature, and the temperature difference between day and night will also change greatly. Generally speaking, 0 -4 degrees can not inhibit the growth of bacteria. In addition, homebodies, in particular, should change stale ingredients regularly, and if they find a little bad fruits and vegetables, they should be removed as much as possible.

  From the aspect of staying away from wild animals, at present, the epidemic situation is very related to wild animals, and all kinds of wild animals (food) should be rejected. Of course, there is no need to overdo it. During the epidemic prevention and control period, many people killed and threw pets out of fear, so it is unnecessary. After thousands of years of domestication, human beings can also rest assured of eating meat products of livestock and poultry such as pigs, cattle, sheep, chickens and ducks.

  Chen Wei also specially reminded that in response to epidemic prevention and control, the public must reduce the damage to their own resistance in their diet, including avoiding eating too much unclean food that is easy to upset their stomachs, and paying attention to separating raw food from cooked food and tableware, so as to reduce the disease caused by dietary factors. It brings new burdens to individual resistance.

Geely Galaxy L7 is the first to experience! The car is full of screens, and the fuel consumption at a power loss is as low as 5L. Can it sell out?

On February 23rd, Geely released a new new energy strategy at the main venue of the Hangzhou Asian Games, and simultaneously launched a new mid-to-high-end new energy series – Geely Galaxy, Galaxy L7 as the first model of Geely Galaxy’s intelligent electric hybrid series made its global debut and opened reservations. We have already experienced this new model first. Based on the e-CMA architecture, Galaxy L7 focuses on 200,000-level home users, taking into account intelligence, space, comfort, economy and good power performance. Bring more affordable all-round models to mainstream home users.

What is "Milky Way"?

"Galaxy Series" is a new mid-to-high-end new energy series launched by Geely brand, using a new brand logo. The subsequent Galaxy series will launch "Galaxy Intelligent Electric Hybrid L Series" and "Galaxy Intelligent Pure Electric E Series", a total of 7 products, covering sedans and SUVs.

Galaxy L7 is the first mass-produced model launched by the Galaxy series. It is positioned in the 200,000-class A-class intelligent electric hybrid SUV and targets mainstream household users. Geely aims to create a smart new energy model that combines power, economy, space, cockpit intelligence and intelligent driving, and is priced within 300,000 yuan to meet the choices of more mainstream household users.

Galaxy L7 will be equipped with three smart electric technology technologies: "Aegis Battery Safety System, Raytheon Electric Hybrid 8848, and New Galaxy NOS" for the first time. The new car was launched globally and started small orders, and deliveries began in the first half of the year.

Galaxy ripple aesthetic design

Galaxy L7 is a new A-class intelligent electric hybrid SUV based on the e-CMA architecture, which adopts the Galaxy Ripple aesthetic design concept. Ripple is a very distinctive brand symbol of Geely. In recent years, a number of classic models with different styles of Ripple features have left a deep impression on consumers. The new digital Ripple of Galaxy L7 shows a strong sense of technological beauty in an orderly manner.

The electrified front face of the new car has a simple and clean design. As a plug-in hybrid model, the new car adopts a fully enclosed grille that is closer to the pure electric model. The new car hybrid system adopts the most compact 3DHT design, and the axial length is 354mm, which is the shortest in the same class. The compact power system can leave enough space for arranging windshields and high-power intake fans. While meeting the intake effect, the intake area is reduced from 99,000 to 69,000 square millimeters, saving 30% of the intake area.

At the same time, the engine cooling system on the Galaxy L7 adopts three-layer water cooling technology, which effectively solves the heat dissipation safety problem caused by the closure of the front cabin. It is the innovation of the power system that reduces the constraints on the design of the new car.

The design of the new car’s daytime running lights is inspired by the traditional "flying eaves bucket arch" shape of Chinese classical architecture. The bucket arch supports the roof above and is connected to the columns below, which plays a dominant role in ancient architecture. This design makes the front face of the new car more stable, tense, and recognizable.

The sharp lines on the side of the Galaxy L7 body create a good light and shadow effect, which is very three-dimensional. The side shape of the Fuhu pose and the short back design ensure that there is a large space for the head in the rear row, while the side lines are smooth, lowering the visual center and presenting the feeling of being ready to go. The roof is also treated with the more popular blackening treatment nowadays, and with the downward pressing roof line, it creates a dynamic posture.

In terms of size, the length, width and height of the Galaxy L7 body are 4700/1905/1685mm respectively, and the wheelbase is 2785mm. Compared with the BYD Song PLUS DM-i and Honda CR-V new energy, the wheelbase is longer, which has certain advantages in the same class of models. And the shorter front and rear overhang design will be more beneficial to the interior space.

The rear ripple taillight adopts a through rear taillight design, and the dynamic effect is like water dripping into the lake and slowly blooming. The lighting effect is indeed dazzling, and the recognition at night is also good. In terms of details, the center of the taillight is the English letters of the Geely brand, which look more textured when lit in the blackened through trim.

In terms of color scheme, the new car offers six body colors: Dawn White, Midnight Black, Dawn Grey, Clear Sky Blue, Twilight Mountain Purple, and Galaxy Colorful White. Among them, Galaxy Colorful White Car Paint is the most distinctive, and the car paint depicts the colorful appearance of the Galaxy. It is the first mass-produced colorful white car paint in the world. It is taken from natural environmentally friendly materials, and the nano-scale process brings a silk-like luster and texture. The quality of the car paint is comparable to that of top luxury cars.

Nano-colorful white is also the first time in the world to capture the application of TiO2 mass-produced car paint. It adopts a nano-scale double-layer paint spraying process, one layer is the whitest white on earth – TiO2 paint layer, and then sprayed a layer of film formed by mixing TiO2 and SiO2 to form a nano-scale grating structure. The multiple reflections of light restore the brilliance of the galaxy.

"Pamper the co-pilot" Luxury enjoyment

The most eye-catching feature in the car is the large screen. The Galaxy L7 is equipped with a 10.25-inch instrument + 13.2-inch central control screen + 16.2-inch co-pilot screen, and a 25.6-inch AR HUD is also added to the high-end model (this real model is not equipped). Four-screen intelligent interaction meets the intelligent experience of the whole car.

The new car adopts the Galaxy free cockpit, and the gear shifting mechanism adopts the pocket block design, which is more convenient to operate. At the same time, it also allows the central control part to have more space to arrange more functions. Dual mobile phone placement slots are arranged under the central control screen, with 50w wireless charging capability.

The door panel does not have the conventional door handle of the car. The hidden door handle shape is not only more beautiful, but also takes into account the storage capacity. The 190mm long storage compartment can be placed horizontally on most mobile phones on the market. The top of the door opening list is located at the front of the armrest, and the window lift is designed into a dial-like shape, which is more textured.

The Jingyao star ring light curtain ambient light extending along the edge of the three large screens to the side door of the car forms an encircling effect, the range adopts 3D texture paving board, the industry first adopts three-dimensional relief two-color injection molding process, the visual effect is more transparent, and at the same time, 60 viewing angles are selected in the car to calculate and simulate the 200 million light points to achieve a sense of immersion and wrapping atmosphere. The new car provides three colors of interior color scheme: black, light brown and sky white.

The new car seat gave people a pleasant feeling. It was officially called the cotton candy comfortable seat, which was soft in texture and had excellent comfort. At the same time, it did not feel like it was collapsing, taking into account a good sense of wrapping and support.

Of course, the most outstanding is the "pet co-pilot". The Galaxy L7 adopts a unique asymmetrical design of the main and co-pilot door panel armrests, and the co-pilot door panel armrests are higher to meet the more comfortable hand-holding posture of the co-pilot when riding. The co-pilot has the largest co-pilot legroom of 630mm in the same class, and the zero-gravity comfortable experience filled with memory sponges. In terms of configuration, the queen co-pilot seat with electric leg rest, heating, ventilation, massage, physiotherapy, memory and other functions.

The 16.2-inch co-pilot screen has a large number of built-in sub-screen application ecosystems, creating an exclusive entertainment space for the co-pilot, whether it is to brush Douyin, watch movies, listen to music, or play games. It is also equipped with an independent Bluetooth channel to support external Bluetooth headsets and other devices.

At the same time, the co-pilot supports one-click restoration of the best viewing position, the seat is reclined to 125 degrees, the user can get a vertical field of view of 9.6 degrees, and the distance between the eye and the screen is 860mm, forming a golden viewing position. With electric leg drags, infinity audio, seat massage physiotherapy, etc., it brings users the ultimate audio and video entertainment experience.

The Galaxy L7 also has an independent sound zone for the main and co-pilot. The co-pilot can enjoy an immersive experience wearing a Bluetooth headset, and the main driver can enjoy the sound of the vehicle and headrest. Users can also play the sound of the co-pilot screen through the car stereo, and the main driver can play navigation, driving warning sounds, etc. through the headrest stereo without interfering with each other. However, when passengers are resting, the main driver can also listen to music/navigation through the headrest stereo to ensure that the whole car is silent to avoid disturbing passengers’ rest.

After being equipped with an oversized co-pilot display screen, Galaxy L7 innovatively designed an oversized overhead airbag for the co-pilot. Through its original folding and arrangement, the airbag first pops up in the direction of the windshield and quickly spreads down when it explodes, and shortens the traditional airbag’s 0.06-second ejection time to 0.04 seconds. At a speed of 120km/h, this 0.02 second can strive for a safe space of 0.5 meters for the user. That is, it can reduce the impact force between people and airbags, and can also form a protective net from top to bottom in front of the face to avoid secondary damage from glass fragments, items, etc.

It is worth mentioning that the Galaxy L7 is the first to use the 8155 chip + Galaxy N OS, of which the 8155 mass-produced flagship cockpit chip, as the computing core of the entire smart cockpit, has a 7nm process, 128G storage memory, and super computing power, bringing a fast and smooth interactive experience to the new Galaxy N OS. The system start-up speed, application opening speed, and Keyword Spotting speed are all the fastest in the same class. Keyword Spotting speed has accelerated from "second response" to only 0.5 seconds, the fastest in the world.

At the same time, the Galaxy L7 also has the strongest voice interaction capability at the same level. Through full-screen scanning, it supports multi-tone area recognition, and can also achieve continuous multi-round topic voice communication, as well as the powerful ability of continuous recognition of multiple instructions. It can be said that the whole scene can be seen.

Galaxy NOS is Geely’s full-stack self-developed distributed operating system, which perfectly conforms to the mobile phone operation mode that users have long been accustomed to, and the learning cost is lower. The official introduction of its applications and components is fully atomized, desktop cards and applications can be dragged and added independently, and everyone can freely create their own scene mode.

At the same time, it can achieve seamless multi-terminal flow, breaking down the barriers between hardware and hardware. Based on the latest version of the in-car Autonavi 610 navigation, the mobile phone/car is under the same navigation account. When the WeChat positioning on the mobile phone is opened through the mobile phone Autonavi, the car side can open the Autonavi navigation and automatically transfer the mobile phone navigation positioning to the car side. Some functions of the trial car of this real shot have not been fully released. We will also conduct more comprehensive tests of the Galaxy N OS in the future.

A new generation of Raytheon hybrid

The Galaxy L7 is equipped with a new generation of Raytheon hybrid, composed of a new generation of Raytheon hybrid engine and a new generation of Raytheon electric drive. Among them, the new generation of Raytheon hybrid engine B-Plus with the highest thermal efficiency of 44.26% in the world adopts Geely’s self-developed combustion control technology. The strong typhoon-type rolling flow movement in the cylinder, the mixed air flow speed in the cylinder reaches the subsonic level of 300m/s, helping the Galaxy L7 to achieve the same level of ultra-low power loss fuel consumption of 5.23L, and the CLTC comprehensive battery life of 1370 kilometers.

The new generation of Raytheon electric drive’s original "global three-speed" 3DHT not only has a compact structure and is conducive to layout, but also has a transmission efficiency of 97.5%. It also realizes an intelligent electric drive driven by P1 + P2 dual motors overclocking, which can assist in driving when deeply stepping on the accelerator, and can also achieve ejection start and release more kinetic energy reserves. The electric drive system’s extremely fast power response can generate a sense of thrust in 0.11s, and the maximum torque of the electric drive can be output in 0.26 seconds, allowing users to obtain a more extreme electric driving experience. Its 100-kilometer acceleration reaches 6.9s.

The new car is based on the e-CMA intelligent electro-hybrid architecture, inheriting the safety genes of Geely’s architecture. It adopts a super-high-strength cage body structure, an integrated thermoformed boron steel door ring, a 7-series aluminum alloy anti-collision beam, a clover collapse unloading structure, and a four-horizontal and four-vertical floor structure, among other patented designs, to build a safe fortress for travel in passive safety.

In terms of battery hardware safety, the new car battery pack uses 17 fixed connection points to firmly connect with the body. At the same time, the internal beam of the battery pack is also connected to the body floor beam through 4 high-strength bolts, and the shear resistance exceeds the industry’s common bolts by more than 58%. The bottom is equipped with a 1.2mm thick ultra-high front steel lower guard plate, with a tensile strength of 1200Mpa. At the same time, the front sub-frame has added a battery scratch-proof beam, which is 10mm lower than the battery pack. This is also a unique design in the industry, which can shield most of the damage to the battery pack when the chassis scrapes the bottom and supports the bottom. The new car battery has passed 42 rigorous experimental tests, including the series test of various working conditions, which is also easy to pass. Many of the test conditions are far higher than the national standard.

In terms of battery software safety, based on the powerful cloud computing power of Geely Star Smart Computing Center 8.10 billion billion times per second, the AI computing power support and cloud real-time security protection are given. Geely Galaxy’s "BMS3.0 Battery Doctor", through the "multi-dimensional fusion AI decision algorithm", can protect more than 200 electronic control items in real time, warn more than 50 types of faults, and can accurately predict protection for thermal runaway, battery life, battery cell status, etc., which can improve battery life by 20%. The SHIELD battery protection system realizes intelligent temperature control management of battery packs. In an environment of -30 degrees Celsius, through high-frequency pulse self-heating technology, the battery temperature can be quickly adjusted to about 10 degrees, ensuring that the battery life rate in low temperature climate is more than 90%.

In addition, whether it is charging piles at home or public charging piles in Geely’s charging map (including most mainstream brands), Galaxy L7 can accurately adjust the charging rate status of each battery cell, detect battery health in real time, ensure charging safety, prolong battery life, and provide timely warning of abnormal situations. In the event of a car accident, Galaxy L7 can cut off high voltage power within 0.05s after the collision to ensure the safety of the battery and the personnel on board.

Conclusion

The Galaxy L7 has indeed achieved a quite excellent level in the pursuit of comprehensive performance. The intelligent performance of the configuration is eye-catching, and it has a quite good spatial performance for home users. The power system installed during the same period has shown a bright feature that combines performance and economy in terms of parameters.

Chinese clothes are the epitome of Chinese civilization.

The color of traditional clothing is influenced by the theory of yin-yang and five elements, which can be divided into two parts.Blue, red, black, white and yellowFive colors. Different colors advocated by different dynasties reflect their dynasty characteristics.

The President selected the six most representative dynasties in ancient China:Han, Tang, Song, Yuan, Ming and Qing Dynasties, analyzed their popular clothing colors.

Let’s take a look at what these popular colors have with the introduction of the president ~

 

the Han Dynasty/the Han nationality/Chinese (language)/man

Features: simple and natural

Popular colors: Xuan, Red, White and Green.

In 206 BC, the Han Dynasty was founded.

Influenced by the Taoist technique of Huang Lao advocated in the early Han Dynasty and Confucianism advocated in the period of Emperor Wu of the Han Dynasty and later, the costumes of the Han Dynasty pursued the "essential beauty" of one integrated mass.

△ Eastern Han mural

The clothing colors in Han Dynasty are mainly monochrome and monochromatic, and they advocate dim colors, which are dignified, simple and natural.

Clothing in the Han Dynasty carries the idea of "rule by courtesy and orthodoxy", and the fabric dyeing follows the belief of Yin and Yang and the five elements, and it is noble in dark color and vulgar in light color.

Fashion colors in this period are dark black, red, green and white with low lightness.

 

△ Fuxi map in the tomb of Buqianqiu

 black

After the Han dynasty destroyed Qin, according to the theory of five elements, it took the meaning that Qin destroyed Zhou and water overcame fire, and advocated water virtue.

Shuide is dark black. In the early Han Dynasty, dark black was the noblest color.

△ Han dynasty straight clothes

In the Book of Changes, the source of China culture, dark black was elevated to the status of "Heaven" and was the mother of all colors.

In Taoist thought, this theory was further developed:

Thousands of worlds originated from "Tao", and "Tao" showed the color of black, so the colorful of thousands of worlds grew out of black.

△ Eastern Han mural

Since the period of Emperor Wu of the Han Dynasty, considering the five emperors in ancient times, the order of dynasty change was five elements, so the water virtue was changed to fire virtue, and the red color was taken as the top service.

Therefore, red became the most popular color in the Han Dynasty.

Therefore, the dresses of the Han Dynasty showed the characteristics of alternating red and mysterious.

Red also pinned the Han people’s desire for enlightenment and immortality.

The emperors of the Han Dynasty were keen to seek immortality, and imitating immortals with costumes was the most typical form of expression.

Immortal costumes pay equal attention to inflammation and red, and show awe-inspiring and inviolable momentum.

Nobles in the Han Dynasty like to wear red clothes, trying to imitate the charm of immortals.

white

In the Han Dynasty, white was a color that civilians could wear, and it was also the most commonly used color in clothing collocation.

 

It is natural, unpolished, with the most extreme simplicity and simplicity.

△ Han Xizai’s "Night Banquet Map" Part

White, as the most common popular color in the Han Dynasty, can best represent the ordinary people’s perception and understanding of life in the Han Dynasty.

It not only presents the beauty of the color of the costumes in the Han Dynasty, but also reveals the unique gentleness, gentleness, tolerance and atmosphere of the people in the Han Dynasty.

 

△ Han Dynasty winding clothes

 

green

Nearly half of the figures in Han Dynasty murals, both men and women, were dressed in green clothes, which reflected the popularity of green in Han Dynasty.

△ Han Dynasty murals

There is a poem in The Book of Songs, which says, "I am a green girl, and I am in my heart.". "Gnome" is the collar, and "green Gnome" refers to "the man in green clothes", which shows that the green shirt is the representative of a beautiful image in people’s minds.

△ Han Dynasty murals

In the Han Dynasty, the status of green is second only to red and mysterious, and it is also a color available to civilians, so it gradually became the popular color of clothing in the Han Dynasty.

In addition, green has a sense of peace visually, which accords with the charm of "purity" and "inaction" advocated in the study of Huang Lao advocated by Han Dynasty, and also accords with the beauty of "golden mean" in Confucianism.

△ Han Dynasty clothes

Tang Dynasty

 

Features: wrongly painted gold

Popular colors: crimson, crimson, bright yellow and turquoise.

Tang Dynasty’s clothing style is luxurious and elegant, with bright and bright colors, delicate and complicated patterns, and they like to use bright and contrasting colors to match, which embodies the characteristics of the inclusive and open era in Tang Dynasty.

In the Tang Dynasty, scarlet, bright yellow, crimson purple and turquoise were the most popular clothing colors.

△ Zhou Fang’s "Flower Lady’s Picture"

bright red

If the dynasty had color, Datang must be a delicate and charming color with red flowers and green willows.

Crimson is the most popular color in the Tang Dynasty, and it is often matched with the intermediate green, forming a huge contrast.

Women in this era pursue individuality, just as none of us want to bump shirts today.

△ Tang Zhangxuan’s "Mrs. Guo You Chuntu" part
