News on China's scientific and technological development.


Western sources often take the stance "Its not quantity, its quality that counts.," while also suggesting there is a certain amount of plagarism in the published works.

Funny, a western source seem to think quantity counts when it comes to Olympic medals - not just the Gold medals but the total number of medals.:D

' To substantiate this claim they often provide statistics that show Chinese published papers are the least cited by researchers from other nations.'

The problem may have to do with language too. First, they will have to find someone who is good in 2 languages and probably with a scientific background too. Not an easy job really. Just look at some of those Hong Kong movies english subtitles. The translation not only missed the subtlety but sounded illogical as well. The same may happen to those chinese scientific papers after the translation and, thus, may explain their popularity among non-chinese speaking scientists.

' To substantiate this claim they often provide statistics that show Chinese published papers are the least cited by researchers from other nations.'

The statement above is not true according this quote from the post above:

ISTIC statistics also showed, the number of Chinese theses indexed by the Science Citation Index (SCI) topped 94,800 in 2007,7.5 percent of the world's total, ranking third after the United States and Britain.

Thomson Reuters 'World IP Today' Report Predicts China Will Overtake Japan and the United States to Become the World's Leading Innovator by 2012
Wednesday December 10, 12:00 am ET

PHILADELPHIA and LONDON, December 10 /PRNewswire/ -- The Scientific business of Thomson Reuters today published World IP Today: "Patented in China -- The Present and Future State of Innovation in China" which looks at current patent trends and speculates how the world of patent information will look in five years. Patent volumes and trends are explored, as well as the underlying causes of increased innovation in China, including economic and government policy factors.

"Findings from the report indicate that China's economy has shifted focus, moving away from traditional agriculture and manufacturing toward innovation-oriented activities," said Bob Stembridge, co-author of World IP Today and manager, customer relations, the Scientific business of Thomson Reuters. "In essence, China has increased its overall research and development budget for the country, introduced tax breaks and monetary incentives to increase indigenous innovation and continued investing in the nation's academic institutions, which have become a driving force behind Chinese patenting."

According to a 2006 report by the World Intellectual Property Organization(1), the patent offices of the U.S., Japan, Europe (EPO), Republic of Korea and China account for 75% of all patents filed and 74% of patents granted worldwide. An analysis of patent volumes over the last five years from these five major offices shows that inventions from China have been growing at a faster rate than any other region. China's shift from a manufacturing-based economy to a knowledge-based one requires foreign companies to re-examine their global IP strategies.

"China has become the third largest patent office in the world in a very short space of time and, if current trends continue, will dominate the patent information landscape by 2012," said Dr. Eve Zhou, co-author of the report and member of the Intellectual Property Consulting Services group at the Scientific business of Thomson Reuters. "Although the predictions of future patent application volume by the five major patent offices are purely mathematical exercises, the inescapable fact is that Chinese patents are here to stay and will continue to evolve in prominence."

what the west says doesnt really matter at the moment. cuz the utilization of highly trained and educated individuals are meant to improve the country's technological capability as well as in other fields that require such qualities ( China is undoubtedly enjoying an unprecedented rate of improvement in these areas. while the west, who prolly wanna claim that they are superior in "quality" are doing worse and worse. well if that's what quality is all about then i rather go for quantity

any more info about the personal supercomputer? speed? memory?
china homemade supercomputer ranked 14th in the world. another one mentioned in 03 was shuguang400a, 7600Billion bytes/second and 10,000billion calculations/seconds..some serious speed they have.

China's supercomputer, which is operated out of the Computer Network Information Center, Chinese Academy of Sciences (CNIC, CAS), is expected to play an important role in the weather forecast during Beijing Olympic Games in 2008.

Used to provide long-distance calculation services based on networking, and with a sustained performance of 4 TFlops, the Lenovo DeepComp 6800–currently China's fastest computer and 14th among the top 500 worldwide–will simulate upcoming weather during the Games. The DeepComp 6800 is 300 times more efficient in numerical simulations than a Pentium 4 (4.2 G) computer, and 30 times more efficient than a computer with a sustained performance of one TFlop.

Currently, the CNIC, CAS has four supercomputers running at 6.4 TFLops, 9.6 TFlops, 11.70 TFlops and 5 TFlops respectively.

New optic fibre trinitarian network planned

China on Friday announced that it will build its first high-capacity optic fibre network nationwide, which is able to carry Internet, TV and phone services through one network.

The Ministry of Science and Technology signed an agreement with the State Administration of Radio, Film and Television (SARFT) on building the national network.

The backbone network of the new one will have a bandwidth of 1,000 G bits, comparing with the current one of 1 G bits. It will allow every user in the network to have a 100-M-bit per second access to the Internet than the existing 1-M-bit access, said a ministry press release.

With such a bandwidth, the network can provide a package of Internet, TV and phone services, instead of services through separated networks.

A regional network has been built in the Yangtze River Delta and put on a trial run for one year since December, 2006, covering about 30,000 users.

"The lab tests and trial run showed the network and related softwares were stable enough for commercial operation," said a ministry official refused to be named.

But the nationwide program is still in a very early stage. The agreement did not mention the timetable of construction nor the cost.

"Although the new network has a high capacity, whether it is able to provide a package service will depend on telecom companies," the official said.

Insiders here said the SARFT was interested in the new network as the existing copper cable network for TV programs was of low capacity and needed updating. But Internet and telecom service providers might not be so eager to give up the existing network and invest much in a new one.

Nobel laureate 'impressed' by China's atom chips

Nobel Prize-winning German physicist Wolfgang Ketterle said Tuesday he was "impressed" by Chinese scientists' progress in creating on chips the bizarre state where thousands of atoms lose almost all their energy and behave as one.

A research team from the Chinese Academy of Sciences (CAS) said it had made over 3,000 rubidium atoms condensate on a thumbnail-sized chip for five seconds at a temperature of almost absolute zero (-273.15 degrees Celsius), a state which Albert Einstein was the first to call "condensation" eight decades ago.

Being the second Asian country to achieve this, only beaten by Japan, China is now "rapidly catching up with the frontiers of the field", Ketterle told Xinhua in an email. He shared the 2001 Nobel Prize in Physics with Eric Cornell and Carl Wieman from the University of Colorado for synthesizing the first condensate.

The team at CAS's Shanghai Institute of Optics and Fine Mechanics (SIOM) used lasers this time to cut Z and U-shaped lines 100 microns wide on the gilded surface of a silicon-based chip and generated a magnetic field around the chip by electrifying the lines.

Rubidium atoms were "trapped" in the magnetic field thus generated and, with the help of laser cooling and evaporation, were gradually frozen to a temperature of 0.0000003K (-272.999 degrees Celsius), almost the absolute zero, said SIOM.

The state of condensation for atoms was predicted by Einstein in 1924 based on Indian physicist Satyendra Nath Bose's theories. Since then, the subject of what's called Bose-Einstein Condensate (BEC) has remained hot among the world's brightest physicists.

Ketterle, now a professor at the Massachusetts Institute of Technology, said, "the main impact of atom chips is to miniaturize the experimental setup of BEC."

Traditional research apparatuses for BEC were usually huge, said Wang Yuzhu, a CAS academician who led the research team. "The magnetic field loops alone could take up half the volume of a floor-standing air conditioner, making it very expensive and difficult to do experiments."

Atoms at the BEC state act at the same frequency, like photons in a laser, but stronger, earlier researches in the field showed.

They can be used for the storage and processing of quantum information, and for atomic clocks used in navigation and space flights, Wang said, adding that scientists worldwide are working on the application of this technology.

Ketterle said, he expected Chinese physicists to "make major contributions (to the field of BEC) in the near future."

China's scientific research abilities as a country is close to being top-notch, and prolly leads the world in some areas already. Li Peng should take some credit for this for stealing so many former soviet scientists in the 90s. but technological advancement is sorta inevitable when your economy is growing fast

It's more significant than the way it sounds. Really.

Beijing, China (XNA) Dec 19, 2008
A multi-functional experiment system for space tribology, developed by the Chinese Academy of Sciences (CAS) Lanzhou Institute of Chemical Physics (LICP), has passed its acceptance check.

The feat, the first of its kind in China, is of special significance for the development of high-performance, space lubricants in this country.

The system is capable of carrying out various experiments on a material's performance of friction and abrasion in various circumstances, ranging from atomic oxygen, ultra-purple light, proton/electronic beams, high vacuum or high/low temperatures, according to Prof. LIU Weimin, director of the State Laboratory for Solid Lubrication at LICP.

More importantly, it could implement tests in an emulated space environment.

The working reliability of a tribology system is a critical factor affecting the life-span and reliable operation of a spacecraft.

So, it is of special significance in systematically deepening the understanding of the influence of the space environment on a lubricant's frictional characteristics and in development of new long-service lubricants and related techniques applicable to the space environment.


China Exclusive: China starts building world's largest radio telescope

China officially started construction of a Five-hundred-meter Aperture Spherical Telescope (FAST), the largest in the world, in a remote southwest region on Friday.

Preparation and research for the project took some 14 years.

The dish-like telescope, as large as 30 football fields, will stand in a region of typical Karst depressions in Guizhou Province when it's done in 2013.

Karst depressions are usually located in regions plentiful in limestone and dolomite, where groundwater has enlarged openings to form a subsurface drainage system.

The facility will greatly improve China's capacity for astronomical observation, according to the National Astronomical Observatory (NAO), the major developer of the program.

FAST's main spherical reflector will be composed of 4,600 panels. Its observation sensitivity will be 10 times more powerful than the 100-m aperture steerable radio telescope in Germany. Its overall capacity will be 10 times larger than what is now the world's largest (300 m) Arecibo radio telescope developed by the United States, according to Nan Rendong, the chief scientist of the project and an NAO researcher.

The project, costing more than 700 million yuan (102.3 million U.S. dollars), will allow international astronomers and scientists to discover more of the secrets of the universe based on cutting-edge technologies, said Zhang Haiyan, an NAO official in charge of construction.

Scientists have so far observed only 1,760 pulsars, which are strongly magnetized spinning cores of dead stars. With the help of FAST, they could find as many as 7,000 to 10,000 within a year, Nan said.

Pulsars have allowed scientists to make several major discoveries, such as confirmation of the existence of gravitational radiation as predicted by the theory of general relativity.

FAST could also be a highly sensitive passive radar to monitor satellites and space debris, which would be greatly helpful for China's ambitious space program.

The telescope could also help to look for other civilizations by detecting and studying communication signals in the universe.

Chinese scientists and officials selected Dawodang, Pingtang County as the site, where a Karst valley will match the shape of the huge bowl-like astronomical instrument.

The sparsely populated, underdeveloped region will provide a quiet environment to ensure the electromagnetic waves, the crucial requirement of operation, are not interrupted by human activities.

Construction of a new residential area about 60 km away also began on Friday to relocate 12 households. By 2013, when the telescope is to be in operation, all 61 farmers will move to their new houses in Kedu town, with farmland allocated by the government.

"The project is beyond my imagination. I'm glad to see that an ordinary old guy like me could contribute to the country's science program," said Yang Chaoli, 68.

The project was approved by the National Development and Reform Commission, the country's top planning body, the Ministry of Science and Technology, the Chinese Academy of Sciences and its subordinating NAO, Guizhou Province and other departments.
