When it comes to the speed of China's development, many of its achievements reflect the characteristic of "fast". Today we have three pieces of good news to share.
1. China's chips ushered in a new breakthrough! A new breakthrough in photonic chip technology.
On May 8, the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences (hereinafter referred to as "Shanghai Microsystem") published an article titled "Heterogeneous integration of lithium niobate on silicon for electro-optic modulation" in the journal Nature. In this paper, a new semiconductor material called "lithium tantalate" is introduced, which is expected to further promote the development of new information technologies such as photonic computing and optical communication.
The so-called "energy is productivity", there is no doubt that the chip is the "technological core" of today's society, and its development is also directly related to the current and future development direction of science and technology.
And we all know that photonic chips produce "light", and the semiconductor chips we use daily produce "electricity" are completely different concepts, so we can think of photonic chips as the next generation of semiconductor chips.
However, the development of photonic chips has not risen to the state of "breaking the ice", which is mainly because of the scarcity of chip materials and extremely high requirements for materials, and the emergence of lithium tantalate has undoubtedly brought a new "opportunity" for this field.
This is not the first time that lithium tantalate has been used by domestic scientists, as early as 2015, Huawei has made a breakthrough in microwave integrated devices based on lithium tantalate for the first time.
Lithium tantalate not only has the advantages of high wall-plug conversion efficiency, but also far outperforms other materials in the design of high-performance microwave voltage control and RF switching devices.
This time, domestic scientists have also made a major breakthrough in the field of photonics, and they have successfully achieved the integration of a series of optical functions through lithium tantalate-based high-performance photonic devices.
This series of optical functions is like a "part", lithium tantalate can control the "switch" and "adjust" the optical signal through the electric field, and a variety of complex optical operations can be realized on the surface of the chip, thus greatly improving the use value of photonic chips.
Some netizens described lithium tantalate as the "soul material" of photonic chips. In fact, lithium tantalate can adjust the parameters of photons through an electric field, which makes photonic chips much more flexible in processing optical signals, not only more efficient, less expensive, but also able to operate in a wider frequency range.
The application prospects in the fields of high-speed communication, precision medicine, and intelligent manufacturing are also very impressive, so this chip is undoubtedly a major "good" for China.
As early as 2011, the state began to implement the "973 Plan", aiming to apply nonlinear optical materials such as lithium tantalate in optical communication and optical computing.
Since 2017, scientists have also improved the material in various dimensions through manual arrangement and other methods, and in general, the improvement of the material itself and the unremitting efforts of scientists have finally made the "bright pearl" of lithium tantalate completely shine.
Lithium tantalate took the lead in realizing the "material self-sufficiency" in the field of photonics, and the development of photonic chips, optical communications, optical computing and other fields will be more rapid under the impetus of this "sharp weapon".
The breakthrough ability and wide range of application scenarios of lithium tantalate have also opened a new "high-tech door" for China, which will not only promote the wide application of photonic chips in the information industry, but also contribute to China's international status and competitiveness in the field of new information technology.
2. China's lunar exploration has created another miracle! Chang'e-6 landed on the far side of the moon with precision.
Since 1958, the former Soviet Union's "Luna 1" opened a "new chapter in human exploration of space", Russia and the United States have also carried out many years of "lunar exploration" programs, we all know that although the "moon" is only 380,000 kilometers away from us, it is fun to go up and "down" is really "down", but on these two things up and down, we can only see in books and movies.
It was not until 2010 that Chang'e-1 "quietly" landed on the moon, and China was eligible to run for the "fourth power in lunar exploration", but at that time, China's national strength was not strong enough, and the strength of lunar exploration could not be compared with Russia and the United States, so it was not until 2019 that China competed to "keep up with that money", when the "United States Kuoshao" proposed the initiative of "returning to the moon in 2024".
As soon as we Chinese hear the word "competition", we will definitely not admit defeat, and sure enough, we promised to be more generous, faster and more accurate to "send" the Chinese to the moon again "before 2023"!
This year's Beijing Winter Olympics "curling" is the "heart" of our Chinese, but "Chang'e" is the "treasure" of our Chinese, compared with the "small" gift of the Olympic Games sent by the United States, we China directly sent a "big" supermarket, but the Americans do not seem to be very concerned, delayed and delayed, and the time of holding it was pushed back.
Back then, it was "big red and purple", and it was "big flash" back then! In 2019, the world's first "seeding" "sprouted" on the far side of the moon; In 2020, "500,000 fans" from all over the world really held a "concert" on the moon; In 2021, the national men's basketball team and the national women's volleyball team "gradually" clarified the "identity" of the next year's Olympic Games.
Said this
Chang'e-1 "gently" landed on the moon in 2010, but then stayed there "quietly" until 2019, when China set the "flag" of "landing on the moon again" before 2023, and Chang'e "energetically" "marched" to Mars!
The trip to space is undoubtedly a "technical challenge" for all countries, and the reason why China dares to promise "before 2023" is certainly not "smeared" out of thin air, and at the same time, the United States has sorted out "the data that went to the moon 50 years ago", and it is impossible to find out the "faults" to prove "whether the Chinese are on the moon this time", and can only "ontology" point out the "flaws" in the calculation time of the quantum theory of space.
But these are just that, after all, the trip to space is not something that a few "dry words" can say, in fact, the most important thing is "whether everyone can drop accurately", quasi-"Americans' moon", then what is reflected is a "big country card", since we want to compare it, we Chinese must be more "new and accurate" than those "developers"!
Perhaps the "vaccine" that scientific and health biologists from all over the world understand at a glance at the "beginning of the year" is "sought after" by the citizens of all countries; After nearly half a year of "careful consideration", front-line scientists carefully planned a "live broadcast" in the "golden scale" of global scientific and technological development, attracting "700 million viewers" around the world.
Perhaps the "International Aviation Alliance" issued a message that "attracted the attention of the world", or perhaps the people of all countries are "waiting and seeing", in short, whether it is "yes" or "no", Chang'e-6 finally landed on the "far side of the moon" "accurately" after a "13-day long march".
From the original "Chang'e-1" to today's "Chang'e-6", we Chinese have gone farther and farther on the journey to space, successfully landing on the far side of the moon, and also taking a key step for the international "aerospace industry", and there is also an "inspiring" spirit of Chinese scientists to make persistent efforts.
Third, the Hongqi H9 luxury car was launched, and a new round of domestic luxury car boom has begun.
With the rapid development of the country's economy, China's automobile market has also developed rapidly, as a part of the national economy, the automobile has also become the "barometer" of the mainland's national economy, which can not only drive the industry, but also closely linked with domestic logistics.
And now the domestic in the field of automobiles has also made great progress, especially in the field of "new energy vehicles" and "intelligent networked vehicles", domestic enterprises have also developed more and more "internationally competitive" models, in January this year, the domestic automobile market rose in an all-round way.
According to the data released by the "data sharing platform", the sales volume of the domestic automobile market reached 10.57 million units in the first half of the year, a year-on-year increase of 45%, and the sales volume also reached 910 billion yuan, which is also the highest record in the history of the domestic automobile market.
The data on the sales of 106 models show that in January this year, the domestic automobile market had the highest sales, reaching more than 1.5 million units, and sales also reached more than 110 billion yuan. Since the beginning of this year, the domestic auto market has embarked on the road of comprehensive growth.
However, this "growth" mainly comes from "new energy vehicles", and the market share of "pure electric vehicles" and "plug-in hybrid vehicles" is also increasing.
It is understood that this year's highest sales in the country is "Wuling Motors", reaching more than 140,000 units, and sales have also reached 4 billion yuan. followed by "Tesla", which reached 100,000 units and sales of more than 20 billion yuan, and then "Geely Automobile", which reached more than 70,000 units.
With the rapid growth of the domestic automobile market, domestic automobile brands have also made great progress, among which the "Hongqi" brand is one of the most representative brands.
The Hongqi brand comes from the "China's first automobile factory", it is the birthplace of the first luxury car "CA72" in the mainland, and the Hongqi brand, which was born in the 70s, is undoubtedly the "pioneer" and "creator" of the mainland automotive industry.
From "CA72" to today's "Hongqi H9", Hongqi brand has never forgotten its original intention and continued to innovate, it is not only a car, but also the "first small step" of China's automobile industry.
And now the new Hongqi H9 from design to production, not only "improvement", but "comprehensive upgrade", not only "car" but also "art", but also "creativity", but also "Chinese elements".
According to the official news of Hongqi Automobile, the official guide price of the new Hongqi H9 model is "159,700 yuan", with "luxury" as the focus and "sports" as the highlight, and its official guide price is also very "close to the people".
The author thinks. Whether it is "new energy vehicles" or "intelligent networked vehicles", Chinese chips have played a "foundational" role in it, and domestic car brands are also setting a new "benchmark" for "Made in China".
