　　[PConline cross review]2019 is coming to an end. For the majority of DIYer, the first half of 19 years belongs to Intel；; In the second half of 19 years, it belonged to AMD.

In the first half of 2019:

　　Intel can still stably suppress AMD’s market share in the first half of the year only by relying on the toothpaste left by Skylake. It can be said that in the DIY market in the first half of the year, Intel still didn’t take AMD as an opponent.One thing said, Intel is really good at playing games.

In the second half of 2019:

　　The first two generations of Ruilong made AMD’s CPU department slightly better. In July, the three generations of Ruilong were AMD’s challenge to Intel:Don’t treat us like ants, the times have changed since today!

　　On the day of summing up at the end of this year, I will send you the annual popular A/I CPU cross-evaluation, which will be used as PConline’s 2019 CPU ranking.

　　This time, only the popular processors were selected as the horizontal selection. If you want to see a more complete ranking, you can click here to enter the 2019 CPU ladder diagram.

Six popular CPUs on e-commerce platform

　　This review is not in ceiling price. In recent years, in addition to the students who installed machines for cost performance, they also installed machines for the pursuit of ultimate performance. Therefore, the sales of high-end CPU are relatively high this year, which is of reference value for adding statistics. However, when the total score is evaluated horizontally, the price will still be added to the scoring item.

　　Based on the sales statistics of multi-e-commerce platforms, we selected six CPU models that sell well every year:

I. Intel i5-9600KF/　i5-9400F

　　“The middle-end main force that takes advantage of the right time and the right place."

　　The first place in sales volume is often occupied by Core i5, but this year’s Ruilong 3600X is also very competitive. In addition, the ninth generation Core i5 came out much earlier than the 3600X, and the accumulated sales volume is more reasonable than the latter.

　　Both CPUs are i5 of the ninth generation, and the sales volume is relatively hot. Here, I choose i5-9600KF as the representative of Intel.

Second, AMD Ryzen 5 3600X

　　"Sales champion in the second half of 2019"

　　During the period when the third-generation Ruilong CPU was just launched, apart from the eye-catching Ryzen 9 3900X and Ryzen 7 3700X, what attracted people more was the Ryzen 5 3600X with 6 cores and 12 threads. Everyone could count the boxes.

Iii. Intel i7-9700K

　　"The most cost-effective game artifact in the high end"

　　If you want to play games, you have to look at Intel. Compared with the situation that game optimization stopped at 4 cores a few years ago, the game’s support for 8-core CPU is not good now, but at least it has been done. Some large 3A masterpieces can really enjoy the performance bonus brought by multi-core, and Intel’s high-frequency and high-energy characteristics are very suitable for game scenes. Cutting the hyper-threading function that has zero effect on games, the i7-9700K is indeed the most cost-effective high-end CPU suitable for playing games this year.

Iv. AMD Ryzen 7 3800X/Ryzen 7 3700X

　　"showstopper that impacts the high-end CPU market"

　　It is also two high-end CPUs that big game players pay attention to, both of which are 8-core and 16-thread specifications. Ryzen 7 3800X can be regarded as a better Ryzen 7 3700X.

　　Although the game is not as good as i7-9700K and i9-9900K, the performance-price ratio and comprehensive performance are weighed together, and they are more worthy of purchase than two Intel high-end CPUs. Here, Ryzen 7 3800X, which is slightly stronger, is selected for comparative test.

V. AMD Ryzen 9 3900X

　　"miracle of 7nm, I/O die and glue MCM packaging"

　　In fact, in terms of miracles, its eldest brother Ryzen 9 3950X is more suitable, but because Ryzen 9 3950X keeps jumping tickets and has been in a "snap-up — — "Out of stock" status, as of the time of our statistics, we have not accumulated much sales, so we can’t be on the list.

　　The CPU of AM4 interface can be packed into 12 cores or even 16 cores, which is closely related to AMD’s newly designed core architecture. CCD+I/O die is more flexible than the big core route that Intel has always adhered to.

VI. Intel i9-9900KF

　　"Can it be used without exceeding 5GHz?"

　　Perhaps because i9-9900K is the flagship CPU launched at the end of 2018, itI lost to the low nuclear display version i9-9900KF.

　　After thinking about it, the value of this CPU should be that it will exceed 5GHz immediately after being bought back, and then it will be used to brush bilibili and visit Weibo, at least in the view of supercontinent. (Manual dog head)

▼Comparison of six CPU specifications: AMD is confident.

　　The CPU parameters are listed here. On the whole, the CPU specifications of AMD seem to be more bright: 7nm+ multi-core+super large three-buffer +PCIe 4.0, and the frequency span between different CPUs is not large. Intel dominates the high-frequency direction, and the frequency span between the mid-range and high-end CPU is large.

Test platform construction

　　Let’s introduce our evaluation platform first.

　　The hardware of the evaluation has been used all the time. The first thing to ensure is that the platform is stable and reliable.

　　As for the motherboard, both Z390 chipset and X570 chipset use ROG HERO series, with the same positioning, which reduces the performance impact caused by different motherboard specifications.

　　The radiator is GI-CX360 water-cooled with overclocking triple mirror. Because the specification span of CPU in this test is large, it will be safer to use 360 water-cooled.

　　The memory is pulled out from four Kiki royal halberds, and the combination of double 8GB is enough to give full play to their performance.

performance test

Theoretical performance test▼

　　The theoretical performance test project will test a variety of traditional running software, and whoever scores high will be powerful, simple and rude.

▍　CPU-Z v1.90

　　CPU-Z test items are divided into single-thread and multi-thread. It can be seen that i7-9700K and i9-9900KF with higher frequency have completely outperformed AMD’s three participating CPUs in single-thread performance, which should be a predictable result without testing.

　　In terms of multithreading performance, Ryzen 9 3900X has no suspense, and the 12-core 24-thread specification crushes the other five participating CPUs. Being both 8-core and 16-thread, Ryzen 7 3800X multi-threaded performance is higher than i9-9900KF with stronger single-core performance.

　　Ryzen 5 3600X with 6 cores and 12 threads is basically the same as i7-9700K with 8 cores and 8 threads, so i5-9600KF can only be a younger brother among them.

▍　CineBench R15

▍　CineBench R20

　　CineBench is a running score software that scores by testing the rendering speed. No matter whether this pile of CPU is in R15 or R20, the multi-thread performance ranking is the same. The multi-threaded performance of Ryzen 9 3900X still surpasses the other five CPUs, and in R20, the single-threaded performance of AMD processor actually surpasses the high-frequency i9-9900KF.

▍　wPrime 2.10 1024M

　　WPrime is a software that tests the computing power of CPU by calculating prime numbers, and it is also very direct and violent. The multi-core Ryzen 9 3900X is still popular, and the testing time is nearly half that of i9-9900KF. The slowest is i5-9600KF, because the number of core threads is relatively small, and Ryzen 5 3600X, which is located close to it, is much faster than it, only 60% of the time.

3DMark Time Spy Extreme physical score▼

　　3DMark’s TSE project is also a software with multi-threading performance. Ryzen 9 3900X is still in the lead, while i9-9900KF with stronger high-frequency single-core performance is about 400 points away from Ryzen 7 3800X of the same specification.

Compressed file performance test▼

　　Compression software is often used by people. Because the compression software algorithms are different, the speed of compressing files among different compression softwares will be different. Here, two compression softwares are selected for testing: WinRAR, which is used by many people, and 7Zip, which comes with Benchmark.

▍　7-Zip benchmark score

　　In the 7-Zip test, the distance between AMD processor and Intel processor is very large. The score of Ryzen 7 3800X is 11.3% higher than that of i9-9900KF with the same core specification, and Ryzen 9 3900X continues to lead.

▍　WinRAR compressed file speed

　　WinRAR, the result here is reversed. Ryzen 9 3900X is 4.3% slower than i9-9900KF, and i5-9600KF is still stable at the bottom. Let’s click on the big picture to compare the other figures.

Performance test of office scenario simulation application▼

　　Most of the test items of PCMark are aimed at daily office applications, such as web browsing and document editing. Ryzen 9 3900X still doesn’t have much advantage, only 1.8% higher than i9-9900KF, which shows that CPU with high frequency and strong single core will be better used in this kind of project.

Professional software application performance test▼

　　Compared with the daily office work above, professional applications will test the performance of CPU more, among which multi-threaded applications are the majority. In theory, Ryzen 9 3900X with more cores will have more advantages.

▍　POV-Ray Benchmark

　　POV-Ray Benchmark is a software for testing the rendering performance of CPU. It can achieve results by rendering a large picture and calculating the average rendering pixels per second.

　　Ryzen 9 3900X outshines others, i9-9900KF is similar to AMD 3800X, while i5-9600KF, which has lost the number of threads, has fallen into the sewer and can’t get out.

▍　FHD X264 Benchmark

　　FHD X264 Benchmark tests and records the rendered frames by exporting the video. Ryzen 9 3900X here is not much different from i9-9900KF, only 6.4%.

▍　ArcTime Pro video compression and export

　　ArcTime Pro is the normal process of exporting video. Here, the performance of Ryzen 9 3900X with more cores is relatively normal, and the distance between i9-9900KF is a little bit.

　　This shows that if you do video work, it will be more popular with more cores/threads. Ryzen 9 3900X has the best performance in these products and is more suitable for video workers. The performance of i9-9900KF is also good. Although the number of cores suffers, the actual performance gap is not as big as the proportion of core numbers.

　　Summary of theoretical performance test:There’s nothing to say about small projects. The core specifications and performance of the processor are here. We can know what’s going on by comparing them. What Supercontinental wants to talk about here is the problem that AMD’s multi-thread performance surpasses Intel’s when its single-thread performance is slightly weak.

　　To put it simply, the SMT technology of Ryzen CPU is a little more powerful than the HT technology of Core I series, and the multi-core utilization rate is higher, which is why the single-thread performance of Ryzen 7 3800X is not as good as that of i9-9900KF in many of the above projects, but the multi-thread performance is reversed.

　　"Multi-frame" is bound to be the trend of future development.Win10 system is a good example. You won’t see the scene of Win7 "one core is in trouble, and N cores are watching" in Win10 system. AMD has made a better decision than Intel on how to optimize the performance of "multi-frame".

Game performance test

　　The number of game masterpieces this year is also dizzying, and the two processor manufacturers are also keen to use game performance as their selling point.

　　Here, six popular online games and 3A masterpieces are selected for testing, and the image quality is uniformly set to 1080P resolution, with the lowest image quality. The reason for this setting is to reduce the influence of graphics card bottleneck and maximize the performance difference of CPU.

▍　Tomb Raider: Shadow

▍　DOTA2

▍　GTA5

▍　Total War: Three Kingdoms

▍　Assassin’s Creed: Odyssey.

▍　Jedi survival: the great escape

　　Game test summary:All six CPUs can make the game run at more than 100 frames, but in Tomb Raider: Shadow, Total War: The Three Kingdoms and The Great Escape of the Jedi, the performance of Intel’s two high-end CPU games has obviously abandoned the rest of the processors.Take the position of the first brother of Intel Games..

　　The "extreme game performance" that Intel has been boasting is indeed well founded.However, the game running at such a high number of frames, except for some e-sports big brothers who use 240Hz screens, can actually ignore this frame gap to some extent.

　　Moreover, our test is based on the setting of 1080P resolution and the lowest image quality. If the image quality is properly raised, the graphics card and CPU will tend to be performance bottlenecks, then the gap between them will be narrowed.

Temperature and power consumption test

　　Because it is impossible to test the power consumption of a single hardware, there have been data errors when the software reads the hardware power consumption information. Here, Nortel instrument power consumption meter is used to test the power consumption of the whole platform, and Tomb Raider Benchmark is used to test the full load of the game.

　　I9-9900KF showed the phenomenon of frequency reduction during the test, and the power consumption was lower when the game was fully loaded and tested by Prime 95 than that of i7-9700K. Combined with the above Tomb Raider game test, the frame number of i9-9900KF in the game was not as good as that of i7-9700K, which can explain this phenomenon.

　　On AMD’s side, the power consumption of three generations of Ryzen processor can be effectively controlled by the 7nm process. The power consumption of Ryzen 9 3900X single baked FPU is only 278W, which is nearly 30W lower than that of i7-9700K, which has the highest power consumption. The former is a "miracle species" with four more cores than the latter.

　　As a result of opening PBO, three generations of Ryzen processor hit a temperature wall of 95°C together when baking FPU to reduce the frequency.

　　Intel processors have much lower power consumption and lower frequency at low frequency. The baked FPU of i5-9600KF with few cores is only 68°C, while the 8-core i7-9700K and i9-9900KF have reached the 90°C mark due to more cores and higher frequency, but the temperature is still lower than that of AMD processors.

Summary of PConline evaluation room

▼Comparison of comprehensive performance of six popular CPUs：

　　Hard to do the test, and finally for this comprehensive comparison table, which is the essence of the whole test.

　　The comprehensive performance gap table is the data obtained by synthesizing all the above test items except temperature and power consumption. Because many items will eat multithreading performance, Ryzen 9 3900X undoubtedly won the comprehensive performance championship.

　　Look at the other contestants, i9-9900KF and Ryzen 7 3800X with the same specifications. Although the latter is blessed by SMT technology, some multithreaded scenes will perform slightly better than the former.However, the game is the strong point of i9-9900KF, which lags far behind Ryzen 7 3800X, and wins by high-frequency performance..

　　Because i7-9700K has no hyper-threading function, even if the game is strong, the multi-threading scene drops too many points, and its comprehensive performance is even worse than that of Ryzen 7 3800X, and even it is almost caught up by Ryzen 5 3600X with fewer cores.

　　There is nothing to say about the i5-9600KF. Except for games, other projects are basically at the bottom, but U is actually a good U, but it just happens to be the cheapest and lowest specification one in this horizontal review.

　　Comparing Intel’s game strengths, there is no suspense, but in fact AMD is not too far behind Intel, which is worthy of surprise.

　　Because our game tests are all set to the lowest quality special effects to enlarge the game performance gap between CPUs, the gap will be even smaller if the high quality special effects are turned on.

　　Cost-effectiveness is also a concern for everyone to buy a processor, but there is no more scientific measurement method, so here is a simple and rude one.CPU price ÷ comprehensive performance percentage, get the unit price per percentage of performance. As a result of this calculation,Ruilong 3600X has the highest cost performance and i5-9600KF has the second highest cost performance..

　　Anyway, the smaller the number, the higher the cost performance.Overall, AMD Ruilong will be slightly more cost-effective than Intel Core..

　　As for the unscientific comparison method, I can tell you responsibly: it is good for everyone to have fun, and everyone has his own scale in his heart.

　　Because the higher the performance, the more difficult it is to improve the performance, so how to calculate here will be that the middle/low-end processors have higher cost performance: because the cost of realizing their performance is very low. High-end processors are expensive, and it takes hundreds or thousands of RMB to improve the performance of 10%. Whether it is worth it or not is a matter of opinion.

▼Summary time for expressing personal opinions — —

　　At the end of 2019, Supercontinental believes that it is meaningless to discuss the issue of "whether the processor performance is excessive".

　　As for the reasons, I don’t need to be embarrassed. Everyone is from the era of the media.The demand for creative CPU has soared., playing games to buy less core high-frequency CPU. For those creators and big UP owners, their demand for CPU performance can be said to be bottomless.

　　Therefore, regardless of the use requirements, all those who say that the CPU performance is excessive should be treated as hooligans.

　　Undeniably, in this year’s CPU market, Intel is still firmly on the throne of the game boss.I also changed my computer for playing games to i7-9700K.In some games with high demand for the stability of game frames, it is indeed better than AMD. (It’s not that I’m black, sometimes I really get stuck playing games with AMD processors.)

Sometimes I just get stuck suddenly and then I get disconnected.

　　On the comprehensive ability, AMD with "excess performance" will be even more brilliant.,In other words, AMD’s processors have become "all-powerful"Ryzen 9 3950X, which has the largest number of consumer platforms, has a higher acceleration frequency than any other Ryzen processor. What’s the concept? Not only do you have multi-core advantages at work, but you can also enjoy high-frequency advantages when playing games.

　　Coupled with the rest of AMD’s product lines, the "ceiling" EPYC Rome CPU with servers, and the weakness is the thread ripper of the fever platform. APU more suitable for the low-end platform will also come, and everyone can find their own heart water products in AMD.

　　This year is the flowering and fruiting period of AMD Ruilong.

　　It’s always good to have competition. AMD’s ZEN architecture has given people renewed confidence in Moore’s Law. In order to continue to consolidate its own market, Intel will also speed up the pace of new products, and ultimately, users will benefit. This year’s new CPU products are worthy of our happiness.

▼Guide for purchasing 6 processors (recommended) — —

▍　I5-9600KF 1399 yuan

　　Like i5-9400F, it is stillThis year, there is a high purchase value of CPU.In office, online games and most 3A masterpieces, it will have better performance, and the owner of Internet cafes should like this CPU better.

　　If the game you play is biased towards Tencent online games and the budget is not much, it will be a better choice.

▍　Ryzen 5 3600X 1499 yuan

　　Compared with the above two i5s, this processor has no price advantage.But the comprehensive performance will be stronger.. With the SMT hyper-threading function, I think it is more suitable for users who usually work and play games moderately, and they can also play games by editing pictures and repairing drawings. Professional performance is better than i5, and the game loses a little bit, but it’s not too bad.

▍　I7-9700K 2899 yuan

　　Subjective opinion:If you want me to recommend the CPU in 2019, I think this is the most fragrant CPU. After exceeding 5GHz, the game performance is off the charts, and it has experienced the latest wave of price reduction, which is very affordable.

　　Objective opinion:The 8-core specification is just right for most games, but it doesn’t have hyper-threading. It may not be as good as AMD’s Ryzen 7 series when dealing with work. It belongs to a processor made for games. After the price reduction, the price/performance ratio is really high. It is recommended for game enthusiasts with little budget.

▍　I9-9900kf3,499 yuan

　　The strongest game processor ordered by Intel, but there is also an i9-9900KS in this series, which is the complete body of the 9900K series.

　　Compared with i7-9700K, it has more hyper-threading function, and it has good performance in both games and work. Personally, it is suitable for game anchors — — Turn off Hyper-Threading when playing the game live, turn on Hyper-Threading when editing the essence live, and release the film quickly.

▍　Ryzen 7 3800X 2599 yuan

　　Ruilong 7Their positioning is equivalent to i9-9900K, but the game is obviously not as good as the latter.

　　Because they all have hyper-threading function, their comprehensive performance is stronger than Intel’s, and they are more suitable for working machines. It is recommended that users with low budget should buy them with good working performance and strong game performance.

▍　Ryzen 9 3900X 3999 yuan

　　4,000 yuan, I don’t think I’ll even know if I don’t have a mine at home.

　　The game is still inferior to Intel.But the comprehensive performance is the strongest here.,Those who pursue extreme productivity can consider it.,Or even more extreme, its eldest brother Ryzen 9 3950X.If you have a gold mine at home, you can also choose a higher-end thread ripper series.

　　That’s the end of this article. It’s not easy to test+code words, more than 5,000 words. If you approve PConline evaluation, please give us a coin-operated attention.

Original chestnuts guoke

People with normal vision read by light. The white paper is brighter and the black words are darker, so the naked eye can distinguish the words between light and dark.

What does the visually impaired read? One is by touch, and there are blind documents to touch. One is hearing. When some books are not translated into Braille, maybe you can find audio books.

If you can’t find a ready-made audio book, how can the blind read an ordinary printed book?

As early as 1913, Edmund Fournier d’Albe, a physicist at the University of Birmingham in the United Kingdom, showed a scanner to help the blind listen to books, named "Optophone" (photoelectric reading device). A few years later, the equipment was transformed into a more practical version by a scientific instrument manufacturer.

In 1920, the magazine reported Scientific American.

When the machine sweeps a line of words from left to right, there will be a sound in the user’s headphones. However, the sound is not speech, but a combination of some notes.

Write the word "write" with notes.

Different note combinations represent different glyphs. For example, the letter T has a horizontal direction and a vertical direction, the horizontal direction is represented by a monosyllabic elongation, and the vertical direction is represented by a chord. The notes used here are the highest to SOH and the lowest to the lowest octave SOH.

The note corresponding to the letter t, Tiffany Chan

The height of the notes reflects the position of the ink on the paper: one horizontal of the T is at the top, just lengthen the highest note SOH, while one vertical of the T has ink from top to bottom, so you can play the five notes of SOH, FAH, MI, ME and DOH at the same time, which is a chord.

Then, when the letter T appears, the earphone should first emit a continuous SOH, with a short chord in the middle, and finally return to the continuous SOH. A letter, a word or a paragraph can be "written" with a string of notes:

The note combination corresponding to the word "Type" is Tiffany Chan.

As long as you are familiar with the correspondence between letters and note strings in advance, the blind can hear the contents of a book.

Translating glyphs into notes is not complicated in terms of rules, but it is only part of the work of this machine. Before that, it must first see what font is printed on the book before it can begin to translate.

Therefore, automatically scanning text is the most important thing.

Selenium can see black and white.

At the beginning, the naked eye can distinguish the words on the paper by light. The light returning from black letters is very weak, not as strong as the reflection of white paper. But how does the machine achieve similar perception?

Scientists thought of selenium, and the resistance of this substance will change with the intensity of light. Connect batteries on both sides of selenium. When the light hits the ink mark and then reflects to the surface of selenium, the resistance of selenium will be larger, and the current passing through it will be smaller. When light is reflected from the blank of the paper to the surface of selenium, the resistance of selenium will be smaller, and the current passing through it will be stronger.

The two sides of selenium are connected with a power supply, and the current is different with or without lighting [1]

Different lighting conditions will transform different electrical signals, so selenium can be used as a photodetector. When it sweeps a line of words from left to right, the signal strength will change with the alternation of black and white, which is not difficult to understand. The question is, how does the machine know whether the ink position is high or low, such as whether T is above or below?

Use different beams to scan different positions. If you divide a line of words into five layers, you need five different beams of light to scan it. The so-called different light means that each beam of light hits the surface of selenium to produce a unique electrical signal, which is different from other beams of light. Only in this way can we tell how high the light is calling from.

Divide a line of words into five layers [1]

So how do you divide a beam of light into five different beams?

Here is a porous disk with five holes. When the disc rotates at a speed of 30 revolutions per second, a beam of light is knocked over, and the light passing through the disc is divided into five beams, which are five intermittent (or fast flashing) lights.

Porous disc, Wikimedia Commons, reference [1]

When light is reflected to the surface of selenium intermittently, the current passing through selenium will fluctuate. The current fluctuation caused by these five beams of light is different: because the number of holes in five circles is different, the more holes, the more frequently the light is cut off and the higher the frequency of current fluctuation.

So there were five different beams of light. If they are hit at different positions, we can judge whether the light is reflected from a high place or a low place according to the frequency of current fluctuation. It’s not difficult to tell the difference between a horizontal T and a horizontal T.

The disc divides the light into five different beams.

The notes that users hear are also distributed according to the frequency of current fluctuation.

As for what tools to use to sense the fluctuation of current, the sensor in the telephone receiver can be competent. With the technology at that time, current fluctuations as small as 10-6 amps can be detected.

Is it black or white?

Wit, you may find that according to the principle described above, the strong current signal is the blank, and the weak signal is the ink mark. So, the notes that users hear represent not the ink, but the gaps around the ink?

This was the case with the original products in 1913, and those notes that the user did not hear indicated the location of the ink. When the spaces between words are scanned, all the notes will play together. Therefore, the inventor called it "White-Sounding Optophone".

The combination of notes it plays is so complicated that Mary Jameson, the best user, is trained to read only one word a minute on average. But she still became the first blind person to read ordinary printed books.

In 1918, Barr & Stroud, a manufacturer of scientific instruments, improved the equipment and added a second photosensitive element made of selenium to the photoelectric detector. After the light passes through the disc, part of the light still scans the text and reflects to the first photosensitive element; The other part of the light is directly turned to the second photosensitive element without scanning the text.

Add one more photosensitive element. Popular Science

By combining the signals of the two photosensitive elements, the signal of the blank part can be cancelled. In this way, the notes played by headphones represent ink and letter shapes, while the blank parts are muted. This version is also called "Black-Sounding Optophone".

Of course, its advantage is not only that the combination of notes becomes simple. The structure of the original equipment is fragile. Even if someone walks by heavily, some components may slide to the wrong position, which will affect the normal scanning. The improved equipment is much more stable.

In addition, the improved version also adds the function of adjusting the scanning speed, which can scan a line at the fastest time of 5 seconds and at the slowest time of 5 minutes. Users can choose the speed according to their proficiency in recognizing notes.

Mary jameson is reading Walden Lake.

Mary jameson also used an improved version of this "black voice". Later, her reading speed reached 60 words per minute. Mary became a heavy user of photoelectric reading devices from her school days to her later years.

But for most people, the combination of notes may still sound too complicated. Moreover, some letters with similar shapes, such as "u" and "n", are easily confused. In addition to using the threshold, the price is also prohibitive. 35 pounds in 1920 is about 1,500 pounds (about 13,000 RMB) or more today.

In 1920, the average price of a house in London was about 320 pounds.

In addition, the British Association for the Blind was trying to popularize Braille resources to the whole country, and the photoelectric reading device may pose a threat to the promotion of Braille, and it will not be supported by the association, and the sales volume has been pitiful.

However, commercial failure does not necessarily mean technical failure.

Technology that anyone may need.

In 1949, the engineers of RCA borrowed the principle of photoelectric reading device to create a new reading machine for the blind.

RCA reading machine, which can play the pronunciation of letters, such as "A-"[5]

It also needs to strike the light on the paper and then reflect it on the photoelectric element, thus distinguishing the shapes of letters; It also has a horn, which is responsible for shouting the corresponding sound.

However, the light-emitting device is no longer a lamp with a porous disk, but a cathode ray tube; The photoelectric element is no longer selenium, but photocell; What the trumpet calls out is no longer a note representing a glyph, but a real letter.

Most importantly, there is an additional component in the middle called "electronic analyzer". After receiving the signal from the photoelectric element, it has to pick out the letter that matches the signal from 26 letters before it can command the speaker to read it.

A mainstream view holds that this is the first device in the world that can complete the Optical Character Recognition (OCR) task.

Photo translation AFP

Later, with the development of computer technology, OCR algorithm became more and more sophisticated. Nowadays, artificial intelligence/machine learning has injected a handful of souls into OCR.

Nowadays, OCR serves more than blind people. There may be a moment when everyone needs to copy a large paragraph of text in a picture, or take pictures of foreign characters and throw them directly to translation software. People even think that it is a matter of course to use such technology.

But the first person who made the concept of OCR possible may be Dr Edmund Founier Dalbet, who invented the photoelectric reading device more than 100 years ago.

　　The supermarket paper towel wedding dress, known as the "masterpiece of supermarket aunt", became a hot spot for forwarding and commenting as soon as it appeared in Weibo. As a result, various creative displays against the sky, such as toothpaste bicycles, towel tropical fish and mat armor soldiers, began to appear frequently … The reporter visited Changsha supermarket and learned more detailed stories behind these amazing "masterpieces". Network observer (reporter) Li Jin

　　Recently, some creative supermarket product display photos have been circulated wildly on the Internet, among which Weibo, the model of tissue wedding dress, has the largest forwarding volume. Because many supermarket waiters are already aunts, these creative displays have also been praised as naughty "supermarket aunts" by netizens. "I just went to the supermarket and met a sexy beauty. I found that supermarket aunts are all talents, and I admire them. I specially photographed them to share with you! " Some netizens commented on Weibo.

　　@ News Background: Supermarket aunt works against the sky

　　Recently, Changsha netizens have also found mop lucky plates, mahjong mat armor and cute fruits in the supermarket … Mr. Li, a citizen, went to the second floor of Wonderful Life Supermarket to buy fruits. As soon as he entered, he was attracted by a huge "bicycle" on the promotion shelf. Looking intently, it was actually made of hundreds of toothpastes!

　　"How creative!" Mr. Li, who originally only needed to buy fruit, was surprised and bought toothpaste when he saw that the price was very cost-effective.

　　In supermarkets such as Carrefour, there are beautiful wedding dresses made of toilet paper: a tube of toilet paper is wrapped around the model statue, connected from the waist, dragged to the ground, and fixed with paper clips to form an elegant "toilet paper wedding dress"; There are "tropical fish with towels": towels are rolled into rolls, with green and blue towels as the bottom, pink towels as the outline, and a vivid "tropical fish" seems to be swimming … There are also cute cartoon characters piled up with dishwashing cloths, huge "cattail leaf fans" made of mops, handsome "armored soldiers" made of sleeping mats, "Totoro honey pomelo" and other series of works.

　　However, is it really that supermarket aunts are bored and POSE with all kinds of goods? If you think so, you are really "naive". The reporter learned that in fact, this is a "promotional artifact" carefully developed by marketers, and the technical term of anti-God is "creative display".

　　@ 丫丫丫丫丫丫: Behind the supermarket aunt is a marketer.

　　Who came up with these ideas? Is it really a supermarket "aunt" who is idle to kill time?

　　The reporter visited a large supermarket in Changsha and learned that in fact, there are not only supermarket aunts with specific arrangements behind the masterpiece, but more importantly, a group of creative professional marketers.

　　The staff of Carrefour supermarket told the reporter: "This is not the masterpiece of’ Aunt’, but mainly planned by professionals from businesses and supermarkets. Generally, it is only available when manufacturers promote their products. "

　　The reporter learned from several supermarkets that these ideas generally originated from the planning department of suppliers.

　　After they make creative planning, it is time for the supermarket "aunt" to show her talents. "After the supplier designs the shapes and props, he will send someone to the supermarket to lead the waiter to be responsible for splicing the goods." Only in this way can we see those "works of God".

　　In addition, many supermarkets also have their own planning departments and art departments. In order to improve the popularity of supermarkets, they will also make some planning plans for the display of goods.

　　@ 中中中中: Attracting customers and improving sales performance.

　　Why do manufacturers and supermarkets make masterpieces? In fact, the goal of "making you look good" is to "make you pay" and attract consumers and improve sales performance by "aunt’s masterpiece".

　　Just like Li Mian, I just went to the supermarket to buy paper, but I was attracted by the idea of "bicycle" toothpaste. When I saw that it was quite affordable, I bought an extra toothpaste. Many citizens are naturally attracted when they see the creative display in the supermarket. Take a closer look at how it is put out under research, so as to pay more attention to the product.

　　"Ordinary goods display is difficult to attract customers’ attention." Ms. Li, a staff member of Carrefour, said that this kind of creative display can especially attract customers to stop and watch.

　　In addition to the need for creative display for manufacturers’ promotion, supermarkets will also use this creative display to create a festive atmosphere and gather popularity when holidays come. While adding vitality to the supermarket, it can also make customers happy.

[Introduction] Cancer-associated fibroblasts (CAFs) are the key components of tumor microenvironment (TME) and play an important role in regulating cancer progression. However, the underlying mechanism of CAFs activation is still unclear.

On April 8, researchers from the Medical College of Kunming University of Science and Technology published a research paper in the journal Cell Death Discovery, entitled "CXC L12 Alone is enough to reprogram normal fibers into cancer-associated fibers". In this study, the researchers found that cancer-associated fibroblasts (CAFs) significantly induced normal fibroblasts (NFs) to acquire the characteristics of CAFs (called CAFs-like fibroblasts, referred to as CEFs for short), including up-regulating α-SMA and vimentin, enhancing the ability of proliferation and migration, and improving the ability of promoting the migration of lung cancer cells. In vivo, CEFs accelerated the growth of A549 xenograft and induced spontaneous lung metastasis. In particular, inhibition of CXCL12 signaling pathway and STAT3 pathway can reduce the transformation from NFs to CAFs, thus inhibiting the progress of lung cancer in vitro and in vivo. This study revealed that CAFs can promote the transformation of NFs into CAFs-like cells through CXCL12/STAT3 axis, and enhance the growth and metastasis of lung cancer. Therefore, inhibiting CXCL12/STAT3 axis is a promising strategy for the treatment of lung cancer and other CXCL12-dependent malignant tumors.

Research background

01

Cancer-associated fibroblasts (CAFs) are the main components of tumor microenvironment (TME), which promote tumor proliferation, migration, invasion, epithelial-mesenchymal transition (EMT) and drug resistance by secreting growth factors, cytokines and extracellular vesicles, thus promoting tumor development. CAFs is a large number of fibroblasts with α -smooth muscle actin (α-SMA) positive and activated myofibroblast phenotype. Different from normal fibroblasts (NFs), CAFs has stronger abilities of proliferation, migration and contraction. It is generally believed that CAFs mainly comes from NFs where organizations reside, but the mechanism of transforming NFs into CAFs is still controversial.

More and more evidences show that cancer-associated fibroblasts (CAFs) can be activated by signals from tumor cells and matrix environment, which provides a unique insight into the complex interaction in tumor ecosystem. Researchers found that the hardness of extracellular matrix (ECM) can induce mesenchymal stem cells (MSCs) to differentiate into CAFs, thus promoting the invasion and metastasis of triple negative breast cancer (TNBC). In addition, in gastric cancer, CAFs can also "educate" NFs to promote cancer cell proliferation and T cell inhibition. However, the exact mechanism that drives CAFs activation is still largely unknown. Therefore, detailed research is needed to clarify the molecular mechanism of cancer-related fibroblast activation, so as to open up a new anti-matrix therapy approach.

CAFs promotes the transformation from NFs to CAFs in lung cancer.

02

In order to explore the clinical effect of tumor-associated fibroblasts (CAFs) in the process of transforming normal fibroblasts (NFs) into CAFs in lung cancer, the researchers isolated pairs of CAFs and NFs from tumor tissues or corresponding non-malignant tissues adjacent to tumors of several lung cancer patients. CAFs specifically shows highly expressed vimentin and FAP (known CAFs markers), and its ability to promote the migration of lung cancer cells is stronger than that of NFs from adjacent tissues. Then, NFs was treated with CAFs conditioned medium (CM), and then the characteristics of CAFs were analyzed. The levels of CAF markers α-SMA and vimentin expressed in NFs after CAFs CM education increased significantly. These results indicate that CAFs may be helpful to endow NFs CAFs with specific characteristics.

CAFs induces NFs to acquire CAFs characteristics in lung cancer

conclusion

03

To sum up, this study expounds a new molecular mechanism that the interaction between NFs and CAFs promotes the metastasis of cancer cells. CXCL12/ STAT3 pathway is a key participant in NFs-to-CAFs transition, which provides a key therapeutic target for developing new cancer treatment methods.

　　Cctv newsOn December 5, the National Health and Wellness Commission held a press conference to introduce the measures to deepen the implementation of grassroots health care and convenience services. Zhu Hongming, deputy director of the Grassroots Department of the National Health and Wellness Commission and a first-class inspector, said at the meeting that since the deepening of medical reform in 2009, National Health Commission has continuously promoted the equalization of basic public health services, and grassroots medical and health institutions have undertaken a large number of basic public health services, especially the health management of patients with chronic diseases, and have established relatively stable contacts with urban and rural residents. Many urban and rural residents have already felt this service. In promoting the management of chronic diseases, there are mainly the following measures:

　　First, in the grassroots convenience measures, we will promote the full implementation of long-term prescription services for chronic diseases such as hypertension and diabetes in community health service centers and township hospitals, and gradually expand the coverage of chronic diseases; Provide exercise and diet prescriptions or suggestions for patients with chronic diseases such as diabetes, hyperlipidemia and hypertension.

　　The second is to organize the compilation of the National Guidelines for the Prevention and Control of Hypertension and the National Guidelines for the Prevention and Control of Diabetes, so as to guide local primary medical and health institutions to provide health management services for patients with chronic diseases.

　　The third is to actively promote the training of "medical prevention and management" integrated talents and establish a medical prevention and control integration mechanism. Relying on the contract service of family doctors, we will promote the combination of prevention and medical care, do a good job in health follow-up of key populations, and carry out multi-disease co-management services for patients with chronic diseases such as hypertension and type 2 diabetes, mainly through the integration of medical care and prevention.

　　Fourth, relying on the construction of county medical community, promote the establishment of division of labor and cooperation and two-way referral mechanism between primary medical and health institutions and superior medical institutions, and extend the services of superior hospitals to the grassroots. For patients with chronic diseases with stable conditions, health management services are provided by grass-roots institutions in accordance with norms and guidelines. There are some good explorations and practices in this regard in various places, for example, Tianjin promotes the construction of grass-roots chronic disease management centers, and provides residents with online and offline integrated all-round and full-cycle health services through intelligent auxiliary diagnosis, convenient chronic disease assessment, customized treatment programs and personalized health management. Relying on the construction of county medical associations and urban medical associations, Zhejiang Province has realized that the general diagnosis, treatment and daily management of "two chronic diseases" are mainly based on grass-roots medical and health institutions, realizing linkage from top to bottom and smoothing referral channels.

　　In 2022, under the strong leadership of the CPC Central Committee with the Supreme Leader as the core, the city adhered to the guidance of the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, conscientiously studied and publicized the spirit of the 20th Party Congress, thoroughly implemented the spirit of a series of important speeches made by the General Secretary of the Supreme Leader to Beijing, and adhered to the general tone of the work of striving for progress while maintaining stability. Guided by the development of the capital in the new era, we will continue to coordinate epidemic prevention and control and economic and social development efficiently, adhere to the "five sons" linkage service and integrate into the new development pattern, focus on stabilizing the macroeconomic market, effectively promote the improvement of social livelihood, and achieve new results in the high-quality development of the capital.

● Link 01
New car features: positioning high-end China brand SUV and Volvo 40 series are built on the same platform.
Date of listing: the fourth quarter of 2017

　　The Lexus 01 model was officially released on the eve of the Shanghai Auto Show. The car will be produced in the Luqiao base of Geely Group in the future, and will be officially listed in China in the fourth quarter of this year, and will enter the European and American markets in 2019.

　　The appearance design of the new car is very avant-garde, and the visual impact of the front face is very strong. The square front net shape leaves a deep impression. The headlights are integrated with the front air intake grille, and the overall effect is very coherent. The shape of the LED day workshop running lights and turn signals above is very individual.

　　From the side, the new car maintains the style of the previous concept car, adopts a two-color body design, and the black roof and silver decorative strips look very fashionable and unique. In addition, the new car is also equipped with brand-new ribbed spokes. The new car is based on CMA (Compact Modular Architecture), and its wheelbase is 2730mm. It is worth mentioning that the CMA architecture is led by Volvo Cars and jointly developed by Geely Automobile and Volvo Cars. In the future, Volvo’s brand-new 40 family models will be born on this platform.

　　At the rear, the lines of the LECK 01 quasi-mass production car are very smooth and layered, and the taillights are also L-shaped, but the internal light group will be slightly adjusted. The shape of the rear bumper echoes that of the front bumper, and it is equipped with two exhaust ports on both sides.

　　The new car is based on CMA modular architecture jointly developed by Geely and Volvo, so it can provide a variety of power systems in terms of power, including 1.5T three-cylinder gasoline engine, 2.0T four-cylinder gasoline engine, hybrid system and pure electric system. In terms of transmission, the new car offers six-speed manual transmission, six-speed automatic transmission and seven-speed dual clutch transmission. In addition, the new car will be equipped with a four-wheel drive system in the future.

　　Editor’s comment:Lectra 01 was officially unveiled in China on the eve of this year’s Shanghai Auto Show. As a high-end brand of Geely Automobile, Lectra has Geely’s sales channels and Volvo’s technical endorsement, which makes it have good competitiveness and the strength to challenge overseas mainstream brands.

　　Link has set its sights on the hottest SUV market at present. In this highly competitive market, the Lectra 01 model has many bright spots, both in appearance design and powertrain adjustment, which are very international. But as a brand-new brand, there are still some uncertainties. Therefore, if the car can show its advantages in cost performance in the future, I believe it can still win the favor of consumers.

　● WEY VV5
Features of the new car: the same positioning of high-end SUV models, the overall sense of luxury.
Date of listing: within 2017

　　At the 2017 Shanghai Auto Show, WEY officially released two series of VV5 models, namely V5C and V5S, in which V5C is more inclined to the positioning of the city, while V5S is more inclined to sports. In fact, VV5 is the new name of WEYW02, a compact SUV that was unveiled at the Guangzhou Auto Show. It is reported that the new car is expected to be officially listed this year.

　　The front face of the WEY VV5 model basically continues the design style of the previous WEY W02 model. The honeycomb-shaped front air intake grille and the headlight group of LED light sources on both sides are very aggressive, and the shape of the front bumper is also very sporty. The size of the air inlets on both sides of the VV5s model is also more exaggerated, and the visual effect is excellent.

　　The tail shape of WEY VV5 5 car series is very full and heavy. Moreover, the taillight group of the car adopts full LED light source, which has excellent visual effect after lighting and reflects each other with the previous daytime running lights. In addition, the VV5s also uses a bilateral exhaust layout with a total of four outlets, which has a strong sense of movement. In terms of body size, the length, width and height of the car are 4462/1857/1638mm and the wheelbase is 2680mm respectively.

　　In the interior part, WEY VV5 has a simple overall design and a sense of science and technology, and the circular air outlet is matched with the suspended central control display, which also adds a lot of color to the interior. In addition, the new car uses high-tech configurations such as streaming media rearview mirror, 12.3-inch full LCD instrument, parking assistance, uphill assistance and seat heating, which also adds a lot to the new car.

　　In the seating space, the experiencer with a height of 180cm sits in the front row and has three fingers of head space. Keeping the front row motionless, when the same experiencer sits in the back row, he can get more than 2 fists of leg space, and the distance from the head space to the skylight is only 3 fingers. Overall, the car’s head space performance is relatively general.

　　In terms of power, the new car is equipped with a 2.0T engine code-named GW4C20, with a maximum power of 197 HP (145kW) and a peak torque of 315 Nm, which is consistent with the brand-new Haval H6 model. In terms of transmission system, the new car will match the 7-speed wet dual-clutch gearbox.

　　Editor’s comment:VV7, the first model of WEY brand, has been promoted to a new height in terms of exterior design, interior materials, configuration and creating a sense of luxury. At the same time, compared with other SUV models of China brand, it also has considerable advantages. The VV5 model launched this time continues to maintain this advantage, but it is slightly lower in positioning than the VV7 model. In the future, it is believed that WEY brand will continuously enrich its product line, so that the influence of WEY brand will gradually increase. It is believed that with these advantages, VV5 models can occupy a place in the market.

● Chery brand new Tiggo 5
New car features: brand-new appearance design
Time to market: the second half of 2017 is planned.

　　Chery’s brand-new Tiggo 5 was officially unveiled at the Shanghai Auto Show, which opened in April. As a replacement model of the current Tiggo 5, the new car has a brand-new design in terms of appearance and interior, and it is younger as a whole. According to the news we learned before, the new car will be officially listed in the second half of this year.

　　Appearance, the car is based on the concept β concept car, and continues many design elements in the concept car, such as the headlight shape and the design of the front air intake grille composed of multiple groups of diamonds, which also makes the new Tiggo 5 very dynamic. Design. From the tail, the new car is also very chic, and the chrome trim strip connected in the middle of the taillights also adds a bit of visual effect to the new car.

　　In terms of interior, Chery’s brand-new Tiggo 5 adopts the latest interior style of Chery family, and the overall shape is younger. At the same time, the two-color interior color matching is more in line with the aesthetics of young consumers. According to the information obtained before, the new car will be equipped with leather seats, one-button start, engine start and stop, rear seat proportional tilting and multi-function steering wheel.

　　In terms of body size, the length, width and height of the new car are 4338/1830/1645mm and the wheelbase is 2630mm respectively.

In terms of power, Chery’s new Tiggo 5 will use the same 1.5T turbocharged engine as the Arrizo 5 SPORT. According to the declared data, the maximum power is 147 HP (108kW).

　　Editor’s comment:At present, the domestic compact SUV market is very hot, and Chery brand has also performed well in this market before, but with the longer time to market of the Tiggo 5 model, its competitiveness has dropped significantly. The new Tiggo 5, the replacement model, is precisely to regain recognition in this market. The new car has been upgraded in appearance and interior, which is closer to the needs of young consumers as a whole. However, the Tiggo 7 model is also a compact SUV, so there is a certain competitive relationship between them, and it is inevitable that there will be some internal friction. We will wait and see what strategy Chery will adopt in the future.　

● Weilai ES8

Previously, the launch of its first production car, EP9, showed you the strength of this brand-new car in racing, which successfully refreshed the fastest lap times of electric production cars in the North Ring Road of Nurburgring and Shanghai International Circuit.

　　However, Weilai Automobile was obviously not satisfied with this, and then they launched its first SUV model ES8. Compared with EP9, Weilai ES8 model is closer to our life. At the same time, it is very smart for the new car to target the pure electric 7-seat SUV model, because there is no real competitor in this level.

According to the current model, the new car is equipped with 1.5L and 1.5T engines, and its maximum power is 112 horsepower and 150 horsepower respectively. In terms of transmission, a 5-speed manual gearbox or CVT gearbox is available.

　　Editor’s comment:The current Beiqi Sic Bo X55 model was officially put on sale in January 2016, but only one year and three months later, it was introduced at the Shanghai Auto Show, and the speed of upgrading was also confusing. However, from the aspects of appearance, interior, configuration, etc., the improvement of the new Saab X55 compared with the current model is indeed very obvious, and it is also more in line with the tastes of young people nowadays. Therefore, from this perspective, the launch of the new Saab X55 model is still very worth looking forward to, but we will wait and see what changes BAIC’s strategy for the current X55 model will make.

● dongfeng fengshen AX4
New car features: personalized design
Time to market: September 2017

　　Dongfeng fengshen brand’s first small SUV——AX4, was officially unveiled at the Shanghai Auto Show, which opened in April. The owner is a young consumer group with fashion and individuality. At the same time, according to previous news, the car is expected to be officially launched in September.

　　The appearance of dongfeng fengshen AX4 is individual and bold, and the shape of the front air intake grille is unique. The daytime running lights and headlights are designed separately and connected with the front air intake grille, creating a good visual effect. At the same time, the car’s front fog lamp design is also very special, using a rectangular design, huge size, with a dazzling chrome frame next to it. Generally speaking, the appearance of the car can be described as "very fashionable".

　　In addition to the unique shape of the front face, the visual effects of its side and rear are equally eye-catching. The shape of the lower fender on the side of the car is very linear, and the D-pillar and the trunk adopt a large-area contrast color design. The rear fog lamp and the chrome-plated frame around it adopt the style that echoes the front fog lamp.

　　In terms of configuration, the new car will be equipped with a brand-new in-vehicle intelligent interconnection system, and also equipped with in-vehicle Wi-Fi function. In addition, such as ESP body stability control system, tire pressure monitoring, reversing images, front side airbags, side air curtains, and low-speed anti-collision systems are all available.

　　In terms of body size, the length, width and height of the car are 4195/1780/1622mm and the wheelbase is 2580 mm. In terms of power, the car will be equipped with a 1.6L (engine model DFMA16) naturally aspirated engine with a maximum power of 124 HP and a 1.4T (engine model DFMA14T) turbocharged engine with a maximum power of 140 HP.

　　Editor’s comment:In today’s China brand small SUV market, the face value of a car has become one of the key factors considered by the main consumers in this market-young people. And various car companies are also making efforts, taking different routes to build cars that can not only highlight the brand value, but also have enough personality appearance. The AX4 model is also a small SUV model for young consumers, focusing on the design concept.

　　At present, the configuration richness of AX4 is good, but if we look at the China brand SUV with a price of about 100,000 yuan, its cost performance is not so outstanding. From this point of view, whether the AX4 model can successfully seize the market in the future mainly depends on the pricing and future configuration level, and it is expected that the car will give consumers a satisfactory answer when it goes on the market.

● Dongfeng scenery S560
New car features: the new compact SUV is equipped with two powertrains.
Date of listing: October 2017

　　Previously, Dongfeng Scenery officially announced the product master plan for 2017-2020. First, a brand-new compact SUV, Dongfeng Scenery S560, will be launched this year, which will be equipped with 1.5T turbocharged and 1.8L naturally aspirated engines. According to previous news, the car will be officially listed in October.

　　In terms of appearance, the overall design of the car is more fashionable, the front face adopts family-style design language, and the chrome-plated decorative strips with wide front air intake grille run through the central brand LOGO, and are connected with the headlights on both sides, which greatly improves the recognition of the car. At the same time, the car’s black wheel eyebrows and side skirts are matched with the silver anti-friction guard at the rear of the car body, which also highlights its off-road atmosphere.

　　At the rear of the car body, the new car uses a wide chrome trim to echo the design of the front of the car. The design of the taillights is relatively common, but it looks very harmonious. The new car is positioned as a compact SUV with a length, width and height of 4515/1815/1735mm and a wheelbase of 2690mm, which is slightly smaller than that of the Scenery 580.

　　In terms of power, the new car will be equipped with 1.5T and 1.8L naturally aspirated engines. Among them, the maximum power of 1.5T engine is 150 HP, and the maximum power of 1.8L engine is 138 HP. In terms of transmission, there is no relevant information at present, but we guess that manual and CVT models will be launched.

　　Editor’s comment:Dongfeng Scenery 580 has achieved good results in the medium-sized SUV market, with an average monthly sales of more than 10,000 vehicles. It is precisely for this reason that Dongfeng Scenery S560 has been launched, with the main purpose of further expanding the advantages of various market segments and improving the market competitiveness of Dongfeng Scenery. In the China brand compact SUV market, the competitive pressure is also very great. The competitors also include Baojun 560, Emgrand GS, Changan CS75 and many other strongmen. In the future, I believe that this car will be recognized by consumers with its good configuration and power performance after listing.

● Junma’s first SUV model
New car features: Zotye’s brand-new brand locates young people.
Date of listing: November 2017　

　　A few days ago, we obtained the latest road test spy photos of Junma’s first SUV model from relevant channels. It is reported that the new car will adopt a 7-seat layout in the future and will also be equipped with a 1.5T turbocharged engine. In addition, according to previous news, the new car is expected to be unveiled in November.

　　Externally, the new car adopts a brand-new design language, and the large-mouth air intake grille is decorated with T-shaped chrome. At the same time, the "TRAUM" logo in the middle highlights the identity of the new car. From the side, two sharp lines run through the car body, and with the suspended roof design, the side of the new car looks very slender.

"previously exposed Junma’s new SUV spy photos"

　　The tail shape of the new car is consistent with the previously exposed design drawings. The slender tail light group echoes the headlights. At the same time, according to the spy photos exposed before, the exhaust layout of the two sides and the decoration of the vents on both sides of the exhaust port add a touch of movement to the new car.

"previously exposed Junma’s new SUV spy photos"

　　In terms of power, we learned that the new car will be equipped with a 1.5T turbocharged engine in the future. According to the powertrain plan announced by Junma Automobile, the engine will provide a maximum power of 177 HP and a peak torque of 260 Nm.

　　Editor’s comment:Junma, as a brand-new brand, is still very strange to everyone. According to the data, it is a brand-new subsidiary of Zotye Automobile Group. In recent years, Zotye has been controversial in its design, and in order to remain competitive in the SUV market, Junma brand has become a breakthrough.

　　In the future, Junma Automobile will mainly target young consumers and young families, launch more models in the next decade, and use a brand-new logo to distinguish it from Zotye’s products. According to the plan, Junma will first develop fuel vehicles, focus on SUV and car products, and gradually promote new energy vehicle products. It is planned to launch nine brand-new models within three years.　

● Na Zhijie U5 SUV
Features of the new car: focus on the young market and comprehensively lay out SUV models.
Date of listing: the fourth quarter

　　Na Zhijie released its brand-new small SUV at the Shanghai Auto Show in April, and recently, the car was officially named U5 SUV. In addition, according to the information we have obtained before, the official launch time of the new car is in the fourth quarter of this year.

　　The front face of the new car adopts a big mouth design similar to that of Rui 3, the middle net is painted in black, the headlights on both sides are sharp in shape, and the black decorative strip running through the front fender extends backwards from the outer corner of the headlights, which makes the headlights look very sharp. On the whole, the front shape of the new car not only continues the family characteristics, but also increases the unique personalized detail design.

　　On the side, the new car adopts a slip-back design similar to that of the excellent 6 SUV. The front fender molding is transformed into a waistline from the front door and extends backwards, while the second waistline is drawn backwards from the upper edge of the chrome-plated molding behind the black front wheel brow. In addition, the new car is also equipped with double five-spoke large-size aluminum alloy wheels and roof rack. Overall, the new car has a strong cross-border atmosphere.

　　Judging from the previously exposed interior spy photos, the interior of U5 SUV follows the design elements of Nazhijie’s family style, and its shape is basically the same as that of Rui 3. Rules for dividing areas such as central control display screen and air conditioning control area. At the same time, as a small SUV focusing on young sports, the carbon fiber effect material is also used near the handlebar to create a strong sense of movement.

　　In terms of power, we expect that the new car will share the 1.6L engine of PSA Group with the new excellent 6 SUV, and the transmission system is matched with a 6-speed automatic manual transmission.

　　Editor’s comment:As a domestic brand, Na Zhijie of Dongfeng Yulong has been deeply involved in the SUV market in the domestic market. The sales of You 6 SUV and Da 7 SUV models are not bad at the initial stage of listing, but with the increasingly fierce market competition, Na Zhijie continues to compete for the market with fresh blood, and U5 SUV models shoulder this mission.

　　In the future, Nazhijie U5 SUV will be equipped with a 1.6L engine from PSA, and for PSA, the market share of its power system can also be expanded through this cooperation. In addition, PSA and Yulong have cooperated with Dongfeng Group. I believe it is not difficult to reach this agreement. We also look forward to the actual driving performance of Nazhijie U5 SUV equipped with this powertrain in the future.

● Wuling Hongguang S3
New car features: the first SUV of Wuling brand
Time to market: within 2017

　　At this year’s Shanghai Auto Show, SAIC-GM-Wuling officially released its first SUV model-Wuling Hongguang S3, which has a wild design and is expected to adopt a 7-seat layout. It is reported that the new car will be officially listed this year.

　　As the first SUV of Wuling, the front face of the new car is designed to get rid of the idea of MPV or micro-surface models, which looks slightly domineering. At the same time, the headlight group is connected with the grille, and the fog lamp and the front enclosure design also show the hardliners.

　　Compared with the front of the car, Wuling Hongguang S3 still has some micro-surface shadows on the side of the car body, which does not have the domineering feeling of SUV, and the visual effect of the smaller rim is relatively simple. In terms of body size, the length, width and height of the new car are 4655/1735/1780mm (1790mm for high-profile models) and the wheelbase is 2800 mm. The body width of 1735mm is indeed a little narrow for a medium-sized SUV. With the body height of 1780mm, the proportion is not harmonious.

　　The tail of the new car presents the visual effect of the suspended roof, and the taillight group uses LED light source, which looks very chic and more exquisite than other products of Wuling, but it still lacks the heavy feeling of some SUVs. In addition, according to the official, the new car is a 7-seat SUV.

　　Wuling Hongguang S3′ s interior adopts two-color color matching design, which has certain vitality. At the same time, the popular floating central control display screen also appeared on the car, and its air conditioning outlet is also equipped with a quartz clock, which has a certain sense of grade. In addition, configurations such as electronic handbrake also appeared on the car.

　　In terms of power, the new car will provide 1.5L and 1.5T engines. Refer to Baojun 730. The maximum power of these two engines is 112 HP and 150 HP respectively, and the peak torque is 147 Nm and 230 Nm respectively. At the same time, the car uses the driving form of engine front and rear drive, and the rear wheel is equipped with independent suspension, which is commendable.

　　Editor’s comment:Wuling Hongguang series cars can be described as a topical "magic car". Of course, there are reasons for this. In 2015 and 2016, the car created a total sales volume of 655,000 and 650,000 respectively, maintaining the best sales record of a single domestic passenger car, and the car has long occupied the top position in the MPV rankings. Therefore, after Wuling announced the launch of SUV models, most consumers are still very concerned.

　　However, after the appearance of Wuling Hongguang S3 model, the controversy about the appearance of the car has been going on, but I think that different people have different opinions on the appearance. Although everyone has disputes about the appearance, it does not affect his position in the hearts of consumers. After all, the characteristics of Wuling brand’s own topic attribute have also continued to this model. Whether the car can become an "explosive" SUV model in the future depends on whether it can surprise consumers in terms of price.

● Dongfeng demeanor MX3
New car features: brand-new design
Time to market: It is expected to be listed within this year.

　　As a brand-new compact SUV, Dongfeng Fengdu MX3 was officially released at the Shanghai Auto Show, and the appearance of the new car adopted a different design style from previous models. The power part will be equipped with a 1.6L naturally aspirated engine with a maximum power of 124 HP, and its comprehensive fuel consumption is officially announced to be 7.1L/100km. At the same time, the new car is expected to be officially listed this year.

　　Dongfeng style MX3 front face design is sporty and fashionable, and the silver single chrome trim on the front air intake grille connects the headlight group with the LOGO in the center of the front of the car, and the visual effect is simple and generous. The lower air intake grille is large in size, and the fog lamp areas on both sides are also decorated around chrome trim strips, and a silver anti-scratch guard is added under the bumper. On the tail side, the design of Dongfeng Style MX3 is also relatively simple, using the ups and downs of lines to create a sense of hierarchy.

"The picture shows the Dongfeng style MX3 interior spy photos"

"The picture shows the interior of dongfeng fengshen AX5"

　　The interior of this car was not officially unveiled at the auto show, but judging from the spy photos of the interior we exposed before, the design of the new car is basically the same as that of dongfeng fengshen AX5, so there is not much surprise. According to the information previously declared, Dongfeng Fengdu MX3 will be equipped with skylights, reversing images, side airbags/air curtains, and top luggage racks.

　　In terms of body size, the length, width and height of the new car are 4506/1806/1642 mm (1670)mm after adding luggage rack) and the wheelbase is 2630mm, which is very similar to the size of dongfeng fengshen AX5, so we can judge that it is positioned as a compact SUV. In terms of power, the new car will be equipped with a 1.6L naturally aspirated engine (code-named DFMA16) independently developed by Dongfeng, with a maximum power output of 124 HP (91kW), which is also used in dongfeng fengshen A60, dongfeng fengshen S30 and other vehicles. In addition, it is officially announced that this car has a top speed of 170km/h and a comprehensive fuel consumption of 7.1L/100km.

　　Editor’s comment:At present, Dongfeng Fengdu brand has two SUVs, namely, Dongfeng Fengdu MX6 and Dongfeng Fengdu MX5, which are familiar to everyone. The MX6 model was built on the platform of Laoqijun, while the MX5 is a brand-new model designed by Mr. Yamazaki Gang, the styling director of Zhengzhou Nissan. In addition, the new car and dongfeng fengshen AX7 come from the same technical platform, and the chassis structure is basically the same. It can be said that Dongfeng Fengdu is a product that is widely used by the group resources.

　　The design of Dongfeng Style MX3 has given us a lot of surprises. First of all, its styling design is eye-catching, but the shortcoming is that the interior of the new car is consistent with that of dongfeng fengshen AX5. In addition, the wheelbase of the two cars is completely one, and with similar body size, I believe this car should be a sister model of Fengshen AX5. But as a result, the new car obviously lacks some sincerity in the interior, and we expect the car to surprise us in other aspects.

● Lifan brand new small SUV
New car features: brand-new design style, or named "Pengfei"
Time to market: It is expected to be listed within this year.　

　　Previously, we obtained the application information of Lifan’s brand-new SUV from the Ministry of Industry and Information Technology, which was code-named "CY02C" or positioned as a compact SUV. According to the tail mark in the rear picture, the new car may be named "Lifan Pengfei".

　　According to the declaration, the appearance of the new car adopts Lifan’s latest family-style design language, and the hexagonal large mouth air intake grille and open-corner headlight group on the front face are both popular designs. At the same time, the lower bumper is tough, the fog lights on both sides are simple in design, and the overall front face style is very attractive. From the side, the B, C and D columns of the new car are blackened to create the visual effect of the suspended roof. The rear design of the car body is simple, and the silver anti-scratch guard under the bumper is surrounded by the black bottom around the car body, which makes the car look as wild as an SUV.

　　The body size of the new car is 4390/1820/1715mm, and the wheelbase is 2610mm, which is close to the entry compact SUV. According to different vehicle configurations, the new car will be equipped with tires with specifications of 215/60 R17 and 225/55 R18, and a variety of rim shapes will be available. In addition, the new car will also be equipped with skylights, ESP and so on.

　　In terms of power, Lifan Pengfei will be equipped with a 2.0L naturally aspirated engine of model LF483Q with a maximum power of 141 HP (104kW). According to the spy photos previously exposed, there will be manual and automatic gearboxes for the transmission system of the new car.

　　Editor’s comment:Compared with the tepid in previous years, Lifan brand is gradually coming into people’s field of vision from Xuan Lang and X80 models. From the product layout of Lifan, Lifan has deployed two small SUVs, Lifan X60 and Lifan X50, but the sales performance of these two models is very bleak. Among them, Lifan X50 sold 1,006 vehicles in the first four months of this year, while Lifan X60 sold 2,845 vehicles in the first four months of this year. Faced with the small SUV market full of potential, such performance is obviously not what Lifan wants to see. Therefore, it is very important for Lifan whether this brand-new small SUV that will be listed in the future can capture consumers.　

● Magic Speed S7
New car features: 7 medium-sized SUV models have been added.
Time to market: 4th quarter of 2017

　　Previously, we learned from Beiqi Magic Speed that its new car plan for 2017 will launch three brand-new SUV models S4, S5 and S7 in 2017, and at the same time, it will launch seven MPV models-H5. Recently, we also obtained the declaration map of Beiqi Magic Speed S7 from the Ministry of Industry and Information Technology, which is expected to be listed in the fourth quarter.

　　According to the latest application drawing, the front face of Magic Speed S7 is similar to that of Magic Speed S5 currently on sale. It adopts the family-style "X"-shaped front air intake grille, which is very similar to the design of Lexus spindle front face. In addition, I can vaguely see that the side of the new car is very slender.

　　Compared with the front face, the rear design of the new car is slightly dull, but its huge rear bumper and silver fender highlight the wildness of the SUV. At the same time, depending on the configuration, the car will provide panoramic sunroof and other configurations.

　　As a 7-seat medium-sized SUV, the length, width and height of the new car are 4800/1850/1770(1800 with luggage rack) and the wheelbase is 2780 mm. According to the declared information, the new car will be equipped with a 1.5T engine with a maximum power of 150 HP. We will continue to pay attention to more news about the new car.

　　Editor’s comment:Beiqi Magic Speed has launched a brand-new model very quickly. The Magic Speed S7 launched this time is another SUV model after S3, S3L and S6. Although it belongs to the same SUV model, it has different emphasis on body size and configuration and appearance modeling. The Magic Speed S7 launched this time focuses on practicality and space. In the future, Beiqi Magic Speed will continue to enrich its product line and provide consumers with more choices.

Full text summary:

　　As far as the models and quantity of China brand SUVs to be listed in the second half of the year are concerned, the domestic SUV boom has not declined at all, and the whole SUV market can be described as a heavy gathering with many bright spots, among which Linke 01, WEY VV5, Chery Tiggo 5, changan CS55 and GAC Chuanqi GS7/GS3 are all brand-new or replacement models with high attention. From this point of view, the auto market in the second half of the year is also doomed to more intense competition. Well, that’s all for this issue. If you want to buy a China brand SUV this year, but the products currently on the market can’t enter your eyes, I hope this article can bring you reference.

On August 8, Aouita 11 and its co-branded limited edition model Aouita 011 were officially launched.

Coming to the side, Aouita 11′ s slip-back body and low-lying posture are very dynamic, with prominent wheel arches and straight lines, which bring a little strength and make it more tough visually. The tail contour is round and full, and the integrated through taillight is the main source of tail recognition. It is worth mentioning that the rear of the new car is also equipped with an active lifting tail, which can be lifted when the vehicle is driving at high speed, thus reducing wind resistance and improving high-speed driving stability.

In terms of size, the length, width and height of the new car are 4880/1970/1601mm and the wheelbase is 2975mm respectively. Available in 4-seat and 5-seat space layouts. In terms of body color matching, Aouita 11 offers six color matching options.

As for the interior, Aouita 11 adopts an embracing cockpit to create a strong sense of encirclement for the front passengers. The minimalist interior style has a good texture, which is mainly attributed to the use of NAPPA leather, tufting, flocking, microfiber suede, soft touch paint and other materials, and the sense of luxury meets the standard of this price model. The triple screen composed of 10.25-inch full LCD instrument +15.6-inch floating central control panel +10.25-inch passenger screen has outstanding sense of science and technology. It is reported that its car is equipped with Huawei HarmonyOS OS system, and the control feeling is worth looking forward to.

The eyes came to Aouita 011, and its interior was in black color matching with its appearance. In addition, the interior of the car is also covered with handmade leather. For example, the matte surface of the seat headrest and the upper part of the steering wheel is made of Nuprima leather, and the highlight surface is made of Nappa leather, which makes the sense of high quality more prominent than that of Aouita 11.

In terms of power, Aouita 11 is built on CHN platform, equipped with Huawei DriveONE dual-motor four-wheel drive system, with total engine power of 425kW and total torque of 650N?m. The official 0-100km/h acceleration takes 3.98 seconds at the earliest.
