Remarkable achievement. thanks to China's research in high end materials.

According to WIPO, China accounts more than 55 percent of Global total in Materials/Metallurgy patent grants.

A Chinese research team has successfully completed the country's first full-size superconducting test run for an ultra-high-speed magnetic levitation (maglev) train, which, once completed , will be capable of running at a whopping 1,000 kilometers per hour under ideal conditions.

Developed by the China Aerospace Science and Industry Corporation Limited (CASIC), the T-Flight train project aims to eventually carry passengers and cargo at a speed of 1,000km/h or faster in a low-vacuum tube, which, if successful, would be the world's fastest ground-based transport technology.

A superconducting maglev test line has been built in Datong City of north China's Shanxi Province.

"The test run from static to dynamic is an integrated test of the entire system, integrating many subsystems together. With this experiment, we can preliminarily verify the scientific rationality of the overall design of the high-speed flying train," said Li Ping, member of the project, at a science popularization exhibition about the train in Beijing.

The train will be used for commuting between mega city clusters in the future. Experts say a large number of experiments are still needed to gradually reach the 1,000km/h speed. Previously, the research team has tested a 623km/h speed under non-vacuum conditions.

"We aim to raise the speed to 1,000 kilometers per hour. Next, we will conduct more tests on Phase I test line in Datong to verify the reliability of our entire system. We will further extend our route and conduct some related verifications for longer distances and higher speeds," Li said.

Not sure what they mean with "oscillating spindle in the AB axis", full 5 axis with A and B axis already exist.

They are popular in machining structural aerospace parts
looks like Kede made more breakthrough with CNCs
It always amaze me that the natsec hawks in DC are so concerned about micro-chips but no longer cares about CNCs. This used the national security machine that you can blockade China.
I think they are just claiming that one of the rotational axis is driven by a linear axis with a linkage, I guess this is a world first. I wouldn't call this a "breakthrough", more of a "innovation". I can imagining it has some benefits compared to more typical rotary axis or parallel kinematics. I would guess it increases stiffness and reduces the size of the turret.

Superlattice films developed to achieve macroscale superlubricity​

1682360236270.png


A research group led by Prof. Wang Liping at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS), in collaboration with Prof. Li Qunyang at Tsinghua University, developed a universal superlattice film that can be applied to mechanical parts to achieve long-term macroscale superlubricity with self-rejuvenation. The study was published in Cell Reports Physical Science.

Chemical and genetic analyses of TCM remedies have been conducted since the early 2000s to substantiate the already evidence-based TCM... 3000 years of trial and error. Herbal remedies are already superior to synthetic chemicals as the latter is always harder for the body to digest.

Knowing that something works isn't sufficient for the modern scientific era of medicine. What I would like to see is a sort of nationwide PLA Project 523, where every single prescription in TCM is fully demystified and scientifically categorized, and the mechanisms of action for every compound is thoroughly documented for further pharmaceutical research. I want the whole world to be using drugs like they already use artemsinin, lovastatin, arsenic trioxide, and ephedrine, knowing exactly where the research came from.

Not a SME, but from what I have seen on Western scientific websites, Chinese herbs are tested the same method as Western ones.

Huawei has come out with new data center switch built for diversified computing power (whatever that means), just seems like a new data center switch called CloudEngine 16800-X

it is also looking to sell more supplies for data centers in Vietnam. Is huawei cloud banned from Vietnam? I haven't heard about its presence there.

China plans to put hyperloop, an ultra-high speed pipeline maglev system, into operation by 2035. The first hyperloop train line is likely to be between Shanghai and Hangzhou. The 150km-long tunnel is aimed at allowing maglev trains to travel at speeds of up to 1000km/h.

If the stretch of 1000 km speed was say 125km out of that 150 km, it would just be a small ~7.5 minutes of time.

The whole journey from start to finish might then be at ~10 minutes, although that's only for train start and stop not boarding, check in etc.

A country such as China with a rich history of innovations and a large population pool to work with, the problem shouldn't lie in if talented persons exists or not. This is ancient knowledge, recorded in the infamous Wu Qi's military treatise as early as 400BC(I THINK, it could also be the six secret teachings - 1000bc). The story goes, the king one day finally won an debate within the royal court. The king was very happy about it, but Wu Qi went up and told the king the reaction of his father. His father was not abit pleased after the debate insted he was worrysome. When approached to as why, he commented on that every country have talented people, but if the royal court was supposely composed of the country's most gifted and yet they cannot even win an arguement with the (old)king, then what is left of the country? The current king upon hearing this, walked away in shame.

Ok, the anecdote is finished. A problem that china does have is the brain drain. Where as the scholars especially after 1989 incident, left china to immigrate to other countries. some done it illegally. Whilst the current generation of highschool and university students likes to go overseas and study, and once the students get their diplomas they usually won't go back to China. There is a trend of all the top professors and students in American Universities becoming more and more dominated by asians. However, they are no longer assets of the CCP, and much work needs to be done if CCP wishes to revert this process. Thats not to say they're not doing anything, they're currently focusing on bringing oversea students back.
Instead of focusing to attract these overseas students back, perhaps they should focus on mitigating why so many young talented Chinese are leaving in the first place.
Are Chinese universities that bad which caused such influx of Chinese students to Western mostly American universities?
