In June 2010, Jobs released the classic 4. This generation of iPhone is still three years away from fingerprint recognition, and only three months later, Apple acquired a Swedish company called Polar Rose, which is a small company with only 15 people. Is it anything else that Apple is interested in? It is Polar Rose’s unique face recognition technology. That’s right, this is the predecessor of the Face ID that was carried on the internet seven years later.

Seven years of hard work, iPhone X facial recognition, past lives

　　　　　It is hard to imagine that in 2010, before fingerprint recognition was born, Apple began to lay out 3D vision, and after 7 years of dormancy, it first appeared in the form of facial recognition. So when there is talk that Face ID is just a substitute for the iPhone to solve the fingerprint on the screen in a hurry, we have to admit that we underestimate the Apple Empire.

　　　　Polar Rose’s main technology is to use artificial intelligence to engage in image and video analysis and extract three-dimensional information from two-dimensional images, but Apple’s layout in 3D vision is still one step behind Microsoft’s. Because as early as the E3 exhibition in June 2009, Microsoft officially released Kinect, a somatosensory game device, which changed the way people interact with games. We can play games by shaking our bodies (Nintendo’s Wii still needed a remote control stick).

　　　　　And even the key here is the depth camera, which is used to capture human body movements and then hand them over to the program to identify, remember, analyze and process these movements. This technology is called PrimeSense by a company.Provided by the company.　　　

　　　　　　PrimeSense is an Israeli company founded in 2005, and developed a 3D sensor in 2006. Its founders all have strong scientific research background. At that time, the game industry had been stagnant, and they have been thinking about how to make changes, such as letting people pick up the sword in the game instead of the remote control handle. Finally,PrimeSense locked the camera.

　　　　　At the game developers’ conference that year,PrimeSense showed the prospect of 3D sensors in the game field, and was recognized by Microsoft, which gave birth to the later.Kinect。

3D recognition of the originator’s structural light to achieve PrimeSense

　　　　PrimeSense3D recognition technology is mainly a kind of structured light--—Light Coding (optical coding technology), we know that the camera wants to capture human movements, and it needs to be realized by judging the depth of field. Structured light is to structure light, and its principle is to use a projector to project a grating or a linear light source onto the measured object, forming a distorted shape on the surface of the measured object, such as the bar grating in the picture below, which projects irregular lines on the surface of the fish.

Principle of structured light technology

　　　　Such a distorted image is captured by a camera in another position, and the lines seen from its angle are obtained. When the positions of the projector and the camera are fixed, the distortion degree of the lines captured by it is also consistent, so that the distorted two-dimensional image can restore the three-dimensional imaging of the object surface. Here, the principle of optical triangulation is mainly used.

Principle of structured light technology

Principle of structured light technology

　　　　The Light Coding used by PrimeSense is somewhat different. It will emit a light source called "laser speckle" in space. This light source is characterized by high randomness, and different patterns will appear with different distances, so that the speckles in different spaces are the same. After the light source is emitted, it is equivalent to that the whole space has been marked. When an object is placed in this space, the spatial position of the object can be monitored through the change of speckle.

　　　　　PrimeSense will record a speckle pattern on the reference plane at intervals in space to form a three-dimensional speckle pattern group. When someone enters the space, it will record it again to form a contrast and correlation operation, and then a three-dimensional image of the whole scene can be obtained. This principle is used by Microsoft’s first generation Kinect depth-of-field image.

　　　　Since 2009, technology companies have discovered that 3D vision is a huge treasure that has not yet been tapped, including Microsoft, Intel, Google, Samsung and other companies that have invested in the development of 3D vision through acquisitions and independent research and development. In 2009 and 2010, Microsoft acquired 3D-TOF camera companies canesta and 3dv. In 2013, Intel launched RealSense technology and Google launched Tango project.

　　　　At this point, we haven’t seen much of Apple’s shadow, but since Microsoft announced its parting ways with PrimeSense, Apple has just appeared.

Microsoft’s self-developed TOF Apple Leaks Achievement Face ID

　　　　　In 2013, a new generation of Kinect came out. Instead of continuing to use PrimeSense, it chose to independently develop 3D sensors. In fact, the second generation of Kinect adopts a 3D vision technology-TOF, which is completely different from PrimeSense structured light. These technologies are accumulated from the previously acquired companies canesta and 3dv, which hold the patent of TOF camera. Previously, it was always thought that the first generation of Kinect used TOF technology.

TOF 3D vision (picture quoted from China Electronic Network)

　　　　TOF is short for Time of flight. It is to send light pulses to the target continuously, and then receive the light from the object with a sensor. By detecting the flight (round-trip) time of the light pulses, the distance between the target and the object can be obtained. Usually, the LED emits infrared rays, the imaging sensor receives infrared rays reflected from the surface of the object, and the device emits a sinusoidal signal whose intensity changes with time period, and the depth is calculated by obtaining the phase difference between the transmitted and received signals.

TOF technology principle

　　　　　In addition to structured light and TOF technology, there is also a binocular stereo imaging technology, but it will not be introduced here because the technology is immature.

　　　　　Both structured light and TOF technology have their own advantages in 3D vision. For example, structured light has mature technology, low power consumption and high resolution of plane information, but it is easily affected by illumination, and its performance in strong light is not very good, and its recognition distance is close, but its cost is high. TOF scheme has good anti-interference and long recognition distance, but it has low plane resolution, high power consumption and medium material cost.

Comparison of three 3D vision technologies (picture quoted from Haitong Electronics Research)

　　　　In any case, Microsoft gave up using structured light technology.PrimeSense，Although PrimeSense was somewhat disappointed, it didn’t stop the pace of research and development, and decided to reinvent itself, and developed a very small 3D sensor in the world.CApri and Capri have three times the depth resolution and 50 times the light resistance (enabling them to work in sunlight), but their bodies are reduced by 10 times.

　　　　Maybe it isPrimeSense’s efforts in product miniaturization have enabled 3D sensors to be used in notebooks, tablets and even computers, and also allowed Apple to see its potential. Microsoft is right.The abandonment of PrimeSense finally made Apple miss it..

　　　　　So, finally, in September 2013, Apple officially made its debut and spent $360 million to acquire PrimeSense, which enabled this ambitious company to master the core 3D vision technology.

Those invisible ones behind Face ID are bought in buy buy.

　　　　　Apple’s acquisition of PrimeSense is still advancing the miniaturization of 3D sensors, and increasing investment and patent layout. In April 2015, Apple submitted a patent application for 3D gesture control technology; In July 2015, Apple submitted a facial recognition patent named "Low Threshold Facial Recognition". In March 2017, Apple released a new patent for 3D vision-face recognition using depth of field information, and a complete patent map of face recognition gradually became clear.

　　　　　Then there is a series of crazy acquisitions:

　　　　　In April 2015, Apple acquired LinX Imaging.

　　　　　　　　　　LinX Imaging mainly develops multi-hole cameras for mobile devices, which can reduce the height of the camera and make the camera no longer protrude. Another black technology is to use porous design to accurately measure the difference between pixels in different images, so as to create a depth-of-field image, which allows us to scan the object in three dimensions only by taking pictures.

LinX Imaging 3D scanning technology

　　　　　In November 2015, Apple acquired Faceshift.

　　　　　Faceshift is a motion capture company, which developed the technology of tracking facial expressions in real time and then using animation. This technology was used in Star Wars movies to make the expressions of animated characters imitate the expressions of actors more accurately. In the field of games, users can use avatars that are updated in real time according to their own expressions.　　　

Faceshift expression capture

　　　　　It turned out later that,Faceshift is not only used asIn addition to face recognition, it is also used by Apple in Animoji.

　　　　　In January 2016, Apple acquired Emotient.

　　　　Emotient is a company dedicated to judging people’s emotions through facial expression analysis. This technology will grab people’s faces and then use recognition technology to identify facial expressions.

Perceive facial emotions

　　　　In February 2017, Apple acquired RealFace.

　　　　　RealFace is good at facial recognition. The company has developed a unique facial recognition technology, which integrates artificial intelligence and brings human perception back to the digital process.

RealFace face recognition

　　　　　　　　The large-scale acquisition enabled Apple to quickly master the core technology of 3D vision, especially in the field of face recognition, and also prevented competitors from catching up with Apple quickly through acquisition, so at the new product launch conference in the fall of 2017, X with Face ID function made a stunning debut.

IPhone X facial recognition

The real essence: a quick glance

　　　　　According to Apple’s perfectionist product design concept, X’s "Liu Haier" should not exist, but Jonathan Ive is still willing to make way for "small space", because he also knows that it is not just a full screen on the front that really builds Apple’s next decade, but more importantly, the stunning "that light glance".

　　　　"All along, we have an idea, looking forward to creating such an iPhone: it has a full screen, which allows you to completely immerse yourself in it when using it, as if forgetting its existence. It is so smart, your touch, touch, word, word, even a glance, will get its heart-felt response. And this idea has finally become a reality with the arrival of iPhone X. Now, just meet the future. "

Little space

　　　　Looking back, "Small Space" is highly integrated with Apple’s research results in face recognition, in which the dot matrix projector will project more than 30,000 invisible light spots and analyze them to draw accurate and detailed depth maps for our faces. The infrared lens will read the lattice pattern, capture its infrared image, and then send the data to the security compartment in A11 Bionics chip to confirm whether it matches, using the structured light technology of PrimeSense. In addition, Apple can recognize your face even in the dark through the floodlight sensor and invisible infrared light.

　　　　　Apple chosePrimeSense’s structured light, rather than TOF, pays more attention to the proper recognition distance and high resolution of structured light. Compared with TOF, the lower power consumption also makes structured light more suitable for mobile platforms. However, structured light has a natural disadvantage in strong light. I don’t know if iPhone X can still perform well in the big sun.

　　　　　It is worth mentioning that Face ID is only a part of the energy released by Apple’s accumulated 3D vision for 7 years. In addition to unlocking the face on iPhone X, it also creates a series of functions that seem to show muscles but are very interesting, such as "moving expressions".

　　　　Through the complex system of the original deep camera, iPhone X can analyze more than 50 different facial muscle movements to detect facial 3D contours. On this basis, the "dynamic expression" is derived, that is, the user’s face is captured in 3D modeling. The special effects we often see in movies belong to this category, but this time we can achieve them through mobile phones.

Verbal expression

　　　　Combined with A11 bionic deep learning, Face ID also has the ability of deep learning. It has a special neuron engine, which can use machine learning technology to identify the changes of your appearance. Recently, the white paper on Face ID disclosed by Apple revealed that if your face changes greatly, such as shaving, Face ID will confirm the facial changes through password input and automatically record them in the database, instead of letting you re-enter your face.

Face ID, a small test, Apple’s 3D big move is AR.

　　　　Through patents, we can see that Apple has also reserved a series of 3D gesture operation technologies. Today, when the somatosensory operation has been tepid, we are very happy to see that the future somatosensory operation still needs Apple, a "latecomer", to subvert, and this is the real use of 3D vision.　　　　　

　　　　The 3D gesture operation may be realized on the Mac platform, and the Face ID on the mobile platform is just a small test of 3D vision. Apple said that AR will be an indispensable link in the future, and the energy exerted by the rear dual camera to join 3D vision can not be underestimated.

　AR game

　　　　　At present, Apple has released ARKit development platform, and it has become a huge AR development platform in one fell swoop. However, the AR experience of X is still based on traditional cameras, which is far from 3D cameras. Therefore, when Cook enthusiastically introduced the AR function of iPhone at the press conference, he not only gave the expectation for the next decade, but also had already targeted your wallet for the next decade.

　　　　　　　　The above is a report on the evaluation of Apple’s iPhone products. For the follow-up content of Apple’s iPhone, such as its appearance, screen, photos, battery life and performance, please continue to pay attention to Zhongguancun Online’s report on the evaluation of Apple’s iPhone.

In men’s daily life, shaving is a daily routine. Even in 2019, shaving will still pull the beard? Does the beard make your skin red and tingle? For me who have to shave every day, my skin can’t stand such sensitive stimulation!

It is said that a man whose face is not scratched by a razor is not a real man, but I think this statement is out of date. Modern men’s shaving needs are no longer limited to "shaving clean", but more pursuing a comfortable experience. After all, no one wants to use the "bloody case" that appears from time to time to exude masculinity.

Considering the need of modern men for shaving comfort, Philips recently launched a brand-new SP9880 comfort series electric shaver (hereinafter referred to as Philips SP9880 electric shaver), which really brings "comfortable" shaving feeling to men and opens a new era of comfortable shaving.

Full of luxury, full of dry goods

Philips SP9880 electric shaver is a brand-new "Shushi" series shaver. I was really surprised when the express delivery made me pick up the goods, which actually made me feel a little heavy as a big man.

When I opened the express box, it was really the first time that I saw that the razor box that I could hold with one hand was so big.

When I opened the box, I saw two big men — — Leather storage box and QI wireless charger. The leather storage box is dominated by dark brown, with a heavy texture and full of luxury.

In terms of charging method,Philips shaver is also equipped with the most popular QI wireless charging base, which frees the shaver from the shackles of traditional wires.

In addition, the Qi wireless charging cradle also supports wireless charging of any smart device compatible with Qi.

We can notice that the whole packaging box is divided into upper and lower layers, and the upper layer is removed, and the lower layer we see is the membership card, nursing set, instruction manual and power adapter.

This design can be described as unique, beautiful and reasonable, giving people a full sense of pleasure.

It is worth mentioning that,Philips provides a global warranty for every user who uses this razor for two years, and if it is a registered member, it can extend the warranty for three years.

In addition, the nursing suit was wrapped in an independent package, and I opened it, which contained: snap-in precision trimmer, conversion head, oil control cleansing brush, eye massage head and face massage head. It’s not just women who need grooming. In fact, we men also need to be cared for. Philips’ operation is really intimate.

When I bought Philips SP9880 electric shaver, I got not only an electric shaver, but also a set of all-round household containers for men.

Returning to the key point, I picked up Lipu SP9880 electric shaver. Personally, I feel that this is a finely crafted handicraft. The metallic black and gray appearance has a sense of advanced, which is really suitable for high-end business men. The details are matched with classic rhombic details, which is icing on the cake and shows the low-key luxury of users everywhere.

The arc design of the handle is perfectly ergonomic, and it is rich and solid when held in the hand.

Below the fuselage switch is a large-screen digital display screen, with functions such as remaining power and intelligent reminder at a glance.

In addition to the power on/off key, the left and right addition and subtraction buttons below it are specially designed to meet the individual needs of users. From low to high, you can choose: comfortable, strong and efficient, which are suitable for sensitive skin, deep shaving and fast shaving respectively according to the needs of the scene.

Press the personal comfort button, and the display will immediately light up to remind you.

Find the comfort zone. It turns out that shaving can be so comfortable.

As mentioned above, modern men are no longer just satisfied with the demand of "shaving clean". Finding a "comfortable" circle and getting comfortable is the king’s choice. It is understood that Philips SP9880 electric shaver adopts a brand-new extrasensory comfort circle, aiming to let us men who are deeply troubled by razor violence escape from the sensitive and pulling clutches.

In order to feel the comfortable experience of Philips SP9880 electric shaver and let everyone feel it with me, I used a plaster model to test it — — Pick up the plaster model, then turn on the power button of Philips SP9880 electric shaver and start the comfort mode. Under my violent friction, let’s check how much damage the model has endured.

At the same time, there is no harm if there is no comparison. We took out an ordinary three-headed razor and ravaged this gypsum sphere in every way to see what is the difference between the two razors under the violence test.

Hey? Amazing, why is the plaster model drawn with Philips razor only slightly scratched? Am I not working hard enough? No, I’ve obviously done my best.

I understand,Philips shaving SP9880 razor effectively reduces the contact area between the razor ring and gypsum through the nano-scale new extrasensory comfort ring, thus reducing the friction. Similarly, if I am shaving at this time, I think my comfortable use experience is also because of it!

On the other hand, the violence test with ordinary shaver shows that the gypsum sphere is already full of holes, which is terrible.

It can be seen that the blades of ordinary razors are still very sharp. If such a machine is used to rub my chin, it must be run away, and the redness and tingling can’t escape.

It is worth mentioning that the brand-new extrasensory comfort ring of Philips SP9880 electric shaver is actually a tiny and high-density metal anti-friction coating with special topological structure sprayed on the razor head, which can effectively reduce the friction between the razor head and the skin.

Silky and smooth, I’m not talking about Dove chocolate, this is my real shaving experience.

In order to reduce our sense of friction, it is certainly impossible for Philips to develop this product only with this design. Looking closely at the cutter net of Philips SP9880 electric shaver, compared with previous shavers, it is found that its incision is not only larger than usual, but also subdivides and optimizes the track.

The V-shaped bridge deck of the first track has a larger shaving groove and cutting surface, which completely reduces the problem of beard pulling. In addition, the thickened edge of the knife mesh also increases the comfort of the shaving process. The orbit of the inner ring adopts a circular shaving hole, which can catch the fish escaping from the net with maximum strength, make the chin cleaner and protect the skin barrier at the same time.

Looking back on the essence of shaving, "shaving clean" is still the focus of observation.

A high-quality razor with only comfort is definitely not enough, because "shaving clean" is also the top priority of my consideration.

↑ ↑ ↑ My face is a bit serious after staying up late recently. This is what it looked like before shaving.

↑ ↑ ↑ After shaving, I feel a lot of air.

My face is angular, so it is difficult for ordinary electric shavers on the market to clean my beard in the "black triangle" area, and my beard is not thick, so it is even more difficult to choose a suitable shaver.

Besides, among men, my skin belongs to the type that is not resistant to exercise, and it was quite easy to be sensitive when using a razor before.

Experience: When I turn on the Philips SP9880 electric shaver, I can clearly feel that when the cutter head passes by my chin, it seems that the cutter head will automatically change its angle. My beard will disappear in any passing area, and there is no need to rub it repeatedly. Presumably, this has something to do with the precise blade of nanotechnology.

Philips SP9880 electric shaver has 8-way contour tracking shaving, and the precise cutter head may move in many directions, closely fitting the facial contour, and greatly reducing the friction during shaving.

In addition, considering the difference of each person’s facial contour, this shaver has an intelligent beard sensing system, which increases the strength when encountering a thick beard, and automatically reduces the strength when encountering a soft beard. The shaving strength is controlled very accurately, and it is even more unnecessary for the user to control its strength.

For a person with severe wake-up syndrome like me, I often feel in a daze when I wake up. This intimate shaving experience is really great.

At the end of the evaluation, I didn’t forget to test the use noise of Philips shaver. Just now, when I used it, I didn’t think it was noisy within the human body’s feeling range, and the sound made by touching my face for a short time was not loud.

I tested it with a noise meter, and found that after turning on the shaver, the noise was XXX, which was equivalent to the normal speaking volume in interpersonal communication, and it was still very good.

Shaving is a very important thing in men’s life, and comfort and clean shaving are our requirements for electric razors.

Philips SP9880 electric shaver satisfies our men in three dimensions: clean shaving, comfort and humanization, and opens a new era of comfortable shaving. Super comfort zone, double-track knife net design and intelligent beard induction system all make my shaving process safer and more comfortable; The nano-technology shaving system and 8-thought contour tracking shaving can easily achieve the purpose of shaving.

In addition, Qi wireless charging base and multi-function snap-in accessories add icing on the cake to this high-end razor lineup.

Following my own inner standard of comfort, I think Philips’ brand-new Shushi series SP9880 electric shaver perfectly conforms to all my fantasies about men’s grooming. Interested friends may wish to experience it.

On March 29th, the new conqueror of Futian pickup truck officially launched the diesel 8AT. The whole system adopts the power combination of 2.0T diesel engine and ZF 8AT gearbox, which is divided into chinese odyssey version, Wulin Extreme version and Qitian Dasheng version. The price range is 998-131,800 yuan. It is the first 100,000-yuan diesel automatic pickup truck equipped with 8AT gearbox in China, and it has a very high cost performance. The appearance of the new conqueror model of Futian will promote the product upgrading, ecological expansion and industrial transformation of the pickup truck market in China, and will also enhance the competitiveness of Futian pickup truck and make it better meet the needs of domestic pickup truck users.

During the listing of Futian New Conqueror, the author was invited to participate in the test drive experience of Wulin Extreme Edition. As a mid-range model of Futian New Conqueror series, the new car continues the calm and atmospheric design concept of Futian Conqueror series. The front face is shaped like a lion, and the "flat-headed" front face is angular and very masculine. The body lines are smooth and dynamic, and the wide body with 265/65R17 wide tires looks more domineering and tough. The lines full of strength give people a more reliable feeling, and consumers can choose from a variety of body colors, which enhances the fashion sense of the whole car.

In terms of interior, the new conqueror has upgraded the diesel 8AT in order to better meet the needs of pickup truck users in the new era. The interior adopts a three-dimensional cockpit that runs through horizontally, and the Wulin Extreme Edition is a sporty and fashionable cognac interior.It has 10-inch large central control touch screen, bionic seat, electronic shift lever, openable skylight, multi-function steering wheel and other hardware configurations.It is in line with the trend of the pickup truck market in China, so that users can fully enjoy the convenience brought by intelligent technology, increase the convenience of car use in the later period, and guide users to start a brand-new pickup truck life.

In terms of power system, Futian New Conqueror will be equipped with 2.0T diesel power that inherits the century-old Cummins power technology, with a maximum power of 120kW and a peak torque of 390N·m, matching ZF 8AT gearbox. 4F20TC diesel power has been tested in the domestic pickup truck market for a long time, and it has many advantages such as reliability, strong power, high fuel economy, comfort and quietness. At the same time, the new conqueror is also equipped with Borgwarner timely four-wheel drive system, which has four driving modes of 4H/4L/2H/AUTO, and two driving modes of economy/sport are optional.

The test drive is surrounded by expressways and Panshan Lake.The road is the mainstay, and in this process, the low-speed driving state of the test drive vehicle can be more intuitively realized. Fukuda’s new conqueror gave clear feedback to the driver during the middle and low speed driving, and the throttle and braking force were moderate, which would not produce obvious sense of suddenness and frustration. Sufficient power reserve and good low-torque performance make it easy for Futian new conqueror to start the pickup truck, and the acceleration in the middle and low speed stages is easy, and the power output is relatively linear.

The combination of 2.0T 4F20TC diesel engine and ZF 8AT gearbox can meet the needs of most people, and good power feedback can be obtained in the speed range from 1800rpm to 2400rpm. When driving at a constant speed at medium and low speed, the power will be feedback in time as long as the accelerator pedal is pressed. When it is necessary to speed up overtaking, the engine will be delayed after stepping on the accelerator pedal, and then when the turbine is effectively involved, the engine speed will climb above 2500rpm to help the vehicle achieve further acceleration.

However, as a practical commercial pickup truck, the new conqueror of Futian still retains some characteristics of traditional commercial models in some aspects. Because the flat-bottom container structure is designed to improve the practicability, the center of gravity of the whole vehicle is designed to be high, and the suspension is hard to adjust to meet the heavy load demand, which leads to obvious bumps during the driving of the vehicle. When the vehicle passes through the speed bump or the road with small potholes, the feedback from the front passengers and drivers is relatively small, and the vibration filtering effect is within the acceptable range, while the rear passengers can feel the clear bounce.

After driving on the unpaved road, the high center of gravity and long suspension stroke of the flat-bottomed container pickup make the front and rear passengers feel a more intense bounce, and this bounce will be fed back to the steering wheel, causing the steering wheel to shake and shake.Besides,The steering wheel is caused by hydraulic power.The feedback is strong, which may be laborious for female drivers to control, but it is good for the direction.The directivity is still good, and the vehicle is not too heavy on the way, which is in line with the consumer’s impression of the stability of pickup products.

Generally speaking, Futian New Conqueror is a qualified dual-purpose pickup truck product, which has the right price and positioning.

The state policy has been further liberalized for the society to run medical services.

On May 22, the executive meeting of the State Council proposed to further expand the space for social medical treatment, and the government did not make planning restrictions on the total amount and spatial layout of social medical treatment areas; Allow on-the-job or unpaid medical personnel to apply for medical institutions; To improve the efficiency of examination and approval, all localities should establish a cross-departmental linkage examination and approval mechanism for social medical services before the end of the year. This year and next, we will carry out pilot projects of clinic filing management in 10 cities including Beijing, Shanghai and Shenyang to further promote the sustainable, healthy and standardized development of social medical services, increase the supply of medical services and improve people’s livelihood.

The meeting pointed out that social doctors can obtain land use rights through allocation, agreement transfer, leasing, etc., and can enjoy tax incentives for small and micro enterprises and high-tech enterprises according to regulations, and enjoy the same treatment as public hospitals in terms of hospital grade evaluation and professional and technical personnel title evaluation. Support social medical institutions to cooperate with public medical institutions to develop "Internet+medical health", carry out telemedicine cooperation, and share medical inspection, imaging and other services. Support the society to run medical services and give priority to undertaking rehabilitation and nursing services in tertiary public hospitals.

The reason why people frequently help the society to run medical services is related to the uneven distribution of medical resources in China, and the accessibility of medical resources is still problematic. In order to solve the problem of difficult medical treatment, social medical treatment is expected to become a powerful supplement.

It is understood that at present, there are nearly 220,000 clinics registered and actually operating in China, with an average of more than 7,000 clinics in each province. The average number of practitioners in the clinic is 2.6, including 1.4 doctors and 1.2 nurses. The diagnosis and treatment of common diseases and frequently-occurring diseases in internal medicine, stomatology, internal medicine of traditional Chinese medicine, surgery of traditional Chinese medicine, orthopedics and gynecology account for more than 90% of the clinic business, and play an important role in primary medical services.

However, the development of clinics is facing major problems such as shortage of human resources, low medical service capacity and difficulties in industry supervision.

"The document stipulates that you can only apply for a clinic if you are above the intermediate level and have been practicing in a medical institution for five years. This condition is challenging in itself. First of all, doctors in big hospitals have no motivation to run clinics. It is normal to go out for a clinic and give a lecture. But once they go out to run clinics and practice more, not only the dean is unwilling, but also they take risks, not to mention the doctors in big hospitals have better income and insufficient motivation to come out. Most of the people who want to run clinics are hospitals below the second level, and the places with great demand for clinics are mostly areas at or below the county level. However, this condition is also harsh for them. Many doctors in township hospitals have few doctor qualification certificates. " A doctor at a local clinic said.

According to the above-mentioned clinic doctors, at present, the clinic’s medical information can’t be docked with township hospitals and county hospitals, and only the patient’s information exists in their own computers. However, there are also problems in the transfer level, which can only be transferred through the 120 system, and cannot be directly transferred from the clinic to the higher-level hospital.

In order to further clarify the role and functional orientation of clinics and give play to the important role of clinics in the medical service system, National Health Commission recently issued the Guiding Opinions on Promoting the Development of Clinics (hereinafter referred to as the Guiding Opinions). It is planned to use two years to carry out the pilot work of clinic construction in 10 cities including Beijing, Shenyang, Shanghai, Nanjing, Hangzhou, Wuhan, Guangzhou, Shenzhen, Chengdu and Xi ‘an, and improve the clinics according to the pilot experience.

The above Guiding Opinions simplified the access procedures of clinics, canceled the planning restrictions on setting up clinics, and changed the clinics from practicing licenses to filing management. Revise the basic standards of the clinic, and adjust it from focusing on the examination of equipment and facilities to the examination of doctors’ qualifications and abilities. At the same time, doctors who have been practicing in medical institutions for five years and obtained intermediate or above titles are encouraged to set up specialized clinics full-time or part-time. Encourage the inclusion of clinics in the construction of medical associations, support the large-scale and group development of clinics, and form a standardized and standardized management and service model. Put forward clear requirements for information supervision of clinics. At the same time, the clinic is required to establish an electronic medical record system, standardize the writing and management of medical documents, and ensure the medical quality and safety of the clinic.

　　Xinhua News Agency, Beijing, January 10th (Reporter Hu Zhe, Bai Guolong) After four rounds of argumentation by more than 1,000 high-level experts, 15 project proposals were condensed and formed, and the "Science and Technology Innovation 2030— Work arrangement for the implementation plan of major projects … … At the 2017 National Science and Technology Work Conference held on the 10th, Wan Gang, Vice Chairman of Chinese People’s Political Consultative Conference and Minister of Science and Technology, said that China’s "Science and Technology Innovation 2030— The selection of major projects has been officially confirmed, and the preparation of implementation plans for four major projects, quantum communication and quantum computer, brain science and brain-like research, deep-sea space station and integration of heaven and earth, has been fully launched.

　　In the first year of the "Thirteenth Five-Year Plan", China’s scientific and technological strength and innovation ability have been further enhanced, and major scientific and technological achievements have been highlighted. The achievements of quantum communication, aerospace, deep-sea polar regions, supercomputing, and fourth-generation nuclear power are "resounding and numerous" in the world. According to the "three-step" strategic path mentioned in the Outline of National Innovation-Driven Development Strategy, China will enter the ranks of innovative countries in 2020, enter the forefront of innovative countries in 2030 and become a world science and technology power in 2050.

　　The "Thirteenth Five-Year Plan" is not only a key stage to achieve the first step, but also an important period to lay the foundation for the second and third steps. Wan Gang pointed out that compared with the goal of building a world science and technology power, we still have a big gap: the original innovation ability in important scientific and technological fields needs to be improved urgently, and there are relatively few key core technologies at the leading level; World-class universities, research institutes, innovative leading enterprises, top scientists and innovative entrepreneurs are not enough, and the development of innovation among regions is unbalanced. The supporting and leading role of scientific and technological innovation in economic and social development needs to be strengthened.

　　After years of savings, a new round of scientific and technological revolution and industrial transformation is more and more clearly presented to us, and subversive technologies are constantly emerging. Wan Gang said that speeding up the implementation of a number of major projects that have a bearing on the overall situation and the long term will help China to catch up with and lead the new direction of world science and technology, grasp the strategic initiative of a new round of global science and technology competition, and realize the strategic transformation from running parallel to leading.

　　According to the relevant person in charge of the Ministry of Science and Technology, in accordance with the principle of "one policy", this "scientific and technological innovation 2030— Major projects will innovate organizational implementation methods, strengthen the dominant position of enterprises, and study and put forward policies, measures and incentive mechanisms to encourage local, enterprise and social forces to participate. At present, proposals for major projects such as deep exploration are being studied and demonstrated, and special plans for artificial intelligence are being accelerated.

Recently, I received many calls from parents of students asking about the pronunciation of the Chinese pinyin "O". Students and parents have different opinions on this, including "nest", "oh" and "oh".

After understanding, it is found that many parents will learn pinyin in advance through extracurricular training courses and online courses before their children enter school, in order to reduce the pressure on their children to learn Chinese pinyin. However, the professional level of teachers in these institutions and platforms is uneven, so it is difficult to guarantee the teaching quality. In fact, as a section of Chinese teaching, Chinese Pinyin is not paid as much attention as other sections, such as literacy, writing, reading and writing. Therefore, whether it is teaching seminars or training lectures, there is very little content about Chinese Pinyin, and even professional teachers have little chance to get relevant knowledge training. The pronunciation of "O" is a difficult point in pinyin teaching, because only modal particles such as "Oh" and "Oh" are close to the pronunciation of "O", and modal particles make different sounds because of the speaker’s different emotions and mouth sizes, so it is difficult to pronounce the sound of "O" accurately.

In pinyin teaching, the Chinese Pinyin Scheme is the basis and the curriculum standard is the program. The Ministry of Education once replied in official website that the "O" in Chinese Pinyin should be pronounced "Oh". There are 63 hanyu pinyin, including 6 single vowels. The pronunciation of monosyllabic vowels is characterized by loud voice, good mouth shape when pronouncing, and the mouth shape and tongue position remain unchanged. As one of the monosyllabic vowels, the letter "O" is a round lip sound. In addition to the pronunciation characteristics of monosyllabic vowels, the upper and lower lips are naturally rounded, the back of the tongue is contracted, and the back of the tongue is raised.

The above is a professional way to explain the pronunciation of the Chinese phonetic alphabet "O". In teaching, of course, we can’t explain academic terms and theoretical knowledge to students stiffly. We should learn the pronunciation of letters by teachers’ demonstration and students’ observation of teachers’ mouth shapes. There is another relatively simple and easy-to-learn method: pronounce a "bo" sound first, the sound is prolonged, the mouth shape remains unchanged, and the rest of the sound is "O". By analogy, syllables such as "Po", "Mo", "Fo" and "Wo" are pronounced with a continuous sound length, and the rest of the sounds are also the letter "O". In teaching practice, if it is difficult for students to pronounce the letter "O" correctly, there is no need to force it too much, because when they form syllables with other letters, it does not affect the overall pronunciation of syllables.

Facing the first-grade pupils, pinyin teaching is rich, vivid and intuitive, which can better protect children’s thirst for knowledge in learning Chinese, guide them to acquire new knowledge in interesting games and specific situations, and improve their literacy. In teaching, we can fully tap the resources of teaching materials and develop children’s language and thinking while teaching Chinese Pinyin. In the pinyin teaching part of the textbook, there are a large number of theme maps, which integrate the sound and shape of letters with the specific situations in life, making the originally boring letters become familiar, sensible and meaningful things. In teaching, teachers help students to pronounce correctly, master the shape characteristics of letters and reduce the difficulty of memorizing them by guiding them to practice reasonably in imagination and speaking.

In teaching practice, according to the provisions of Chinese Curriculum Standard for Compulsory Education (2021 Edition), students "can read Chinese characters by using Chinese Pinyin, and learn to look them up in the dictionary by using phonetic order retrieval method and radical retrieval method", which emphasizes the instrumentality of Pinyin learning. The current unified Chinese textbook has also greatly reformed the teaching content of the first volume of grade one, delaying the learning content of pinyin, recognizing and writing some commonly used Chinese characters first, and then learning Chinese pinyin. At the same time, in pinyin teaching, the learning task of word recognition is properly arranged, and word recognition and learning pinyin are integrated with each other. This can make children’s "first impression" of Chinese not letters.ɑO, e ",but the Chinese character" heaven, earth and man ". This adjustment in the order of teaching content is to put Chinese and Chinese characters back to the first place, and Pinyin is only a tool to assist in learning Chinese characters, not an end.

When guiding children to learn Chinese Pinyin, we should accurately grasp the purpose of learning Chinese Pinyin, give full play to the auxiliary role of Chinese Pinyin in literacy and expression, cut unnecessary cumbersome links, create a relaxed, pleasant and diverse learning atmosphere for children’s Chinese learning, and make classroom teaching really reduce burdens and increase efficiency.
