QINGDAO, Shandong, Dec. 26 (Xinhua) -- China's largest rail vehicle maker, CSR Corp. Ltd, over the weekend launched its first test train that features speeds reaching up to 500 km per hour.The six-car train with a fairshaped head is the newest in the CRH series. It has a maximum tractive power of 22,800 kilowatts, compared with 9,600 kilowatts for the CRH380 trains currently in service on the Beijing-Shanghai High-Speed Railway, which hold the world speed record of 300 km per hour.The grey-color train carrying testing and data processing facilities was designed and produced by CSR Sifang Locomotive & Rolling Stock Co., Ltd (Sifang Locomotive), a CSR subsidiary based in the coastal city of Qingdao in eastern Shandong province.Ding Sansan, the company's chief technician, said the concept of the the super-speed train design was inspired by China's ancient sword. The bodywork uses plastic materials reinforced with carbon fiber.Shen Zhiyun, a locomotive expert and academician with both the Chinese academies of sciences and engineering, said the testing of the super-speed train with speeds of up to 500 km per hour will provide useful reference for current high-speed railway operations.

BEIJING, Dec. 28 (Xinhuanet) -- China started to run its own satellite positioning system, Beidou, on Tuesday as the country climbed the global tech ladder and challenged the monopoly of the West. Beidou, or Big Dipper, the domestic version of the US Global Positioning System (GPS), started providing navigation, positioning and timing data on a pilot basis to China and the neighboring area for free on Tuesday, Ran Chengqi, director of the China Satellite Navigation Office, said. The system, with 10 orbiting satellites, covers an area from Australia in the south to Russia in the north. Signals can reach the Xinjiang Uygur autonomous region in the west and the Pacific Ocean in the east, Ran said. With six more satellites to be launched next year, the system will cover a wider area and eventually the entire globe by 2020 with a constellation of 35 satellites, he said. The accuracy of the positioning service will also improve as more satellites orbit. During the trial run Beidou can offer positioning to within 25 meters but when the system is officially launched next year accuracy will be enhanced to within 10 meters, he said. With the system operational China is the third member of an elite group, along with the US and Russia, to develop a satellite navigation system. The US spent 20 years and more than billion on the GPS. Completed in 1994, the system has 24 navigation satellites and is widely used around the world. Beidou has its own unique features, Ran said. "It not only tells users where they are and what time it is but also allows users to tell others the information through short messages," Ran said, adding that this feature is being considered by other systems. Russia's Glonass system achieved a 24-satellite constellation in 1996 but succumbed to funding problems. The rebuilding of the Glonass system is almost finished and Russian media reported that the system resumed service earlier this month. The European Union and the European Space Agency are building the Galileo satellite navigation system. Japan and India also intend to build independent regional navigation systems. "Countries build their own systems because owning an independent satellite navigation system is important to economic development and national security," said Pang Zhihao, deputy editor-in-chief of the monthly publication Space International. There have long been concerns that the US might take its dominant GPS offline in certain international emergencies. Ran said that the Beidou system will be "helpful" to national defense. An "independent and controllable" satellite navigation system can guarantee national economic development as well as scientific and industrial strength, he said. China started to reduce its reliance on the GPS in 2000, when it sent an experimental pair of positioning satellites into orbit. But Ran stressed that Beidou is "built for the world", as the compatibility of various systems enhances reliability for users. "If you only use GPS there will be blind spots. But from demonstrations I saw recently, receivers that are compatible with Beidou will overcome these problems," he said. He encouraged enterprises at home and abroad to join the research and development of application terminals compatible with Beidou. The office put a test version of the system's Interface Control Document online on Tuesday, which is a technical document vital for the manufacturing and development of receivers and chips. The prospects for the country's satellite navigation industry look bright, experts said. Analysts estimated that around 2020 the industry's output will reach 0 billion globally, including 400 billion yuan ( billion) to 500 billion yuan from China. According to the 2011 Report on Application of Geosaptial Information in China released on Monday, the number of satellite navigation application terminals in China has grown from less than 100,000 in 2000 to more than 10 million in 2009. The number is expected to reach 340 million by 2015. An insider said a compatible receiver for car use costs 1,600 yuan to 3,000 yuan, higher than a GPS receiver. "Chips supporting both GPS and Beidou systems have been developed, and terminals have been produced. There are no technical hurdles for the industry," said Han Shaowei, CEO of Beijing-based Unicore Communications Inc, a major navigation chip and core component provider. Beidou application terminals have been put into use in vehicles, such as government cars in Guangdong province. Ran said that private terminal makers in Guangdong are testing their receivers on the road, and the products seem stable. "The price of the compatible terminals is expected to be slashed next year," he said.

BEIJING, Dec. 7 (Xinhua) -- The Chinese government on Wednesday released a white paper on its foreign trade, highlighting the country's achievements in boosting foreign trade and contribution to the world economy.The white paper, titled China's Foreign Trade, was released by the Information Office of the State Council.The white paper introduces China's historic progress, international contribution and policies in foreign trade.

BEIJING, Oct. 8 (Xinhua) -- The rise of China is the definitive economic and political story of the time, yet the 1911 Revolution should not be overlooked, as it was the catalyst that enabled the nation to terminate more than 2,000 years of imperial rule -- one of the longest periods of autocratic rule in the world.China will commemorate the centennial anniversary of the 1911 Revolution, or Xinhai Revolution, with a grand ceremony on Sunday. The legacies of the revolution are set to inspire the world's most populous country with an ancient civilization to continue swimming with the tide of the times, marching on the road to become an empowered modern nation.The 1911 Revolution, which began on October 10, 1911, with an armed uprising, ended the imperial rule established by Emperor Qinshihuang in B.C.221 by toppling the Qing Dynasty (1644-1911) and resulting in a republican government, the first in Asia.Behind the revolution was a burgeoning democratic movement and the rising influence of Western civilization.The revolution not only rid Chinese men of humiliating ponytails and women of the excruciatingly painful foot-binding, but also removed the people's blind faith in the emperor, as well as the fear of foreign powers. The event has since been emancipating people's minds from thousands of years of oppression and self-enclosure.China has become a rising power in sharp contrast to 100 years ago when every country could bully it.Over the past century, the nation united to fight for its destiny and independence. From the Opium War (1840-1842) to the Xinhai Revolution, patriots from all walks of life came together to fight against the imperial autocracy and foreign invasion, with the aim of national rejuvenation by building a country that's respected by the world.Rejuvenation is the common will of the civilization that has existed for over 5,000 years, and no one can halt the process.The 1911 Revolution, led by Dr. Sun Yat-sen, overthrew imperial rule and opened the gate for China's modernization. Yet the dreams of Sun were not fully accomplished, as leaders of the revolution were from the capitalist class and the masses of workers and farmers were not given full play. They still lived in poverty, their democracy and freedom not guaranteed.Ten years after the 1911 Revolution, the Communist Party of China (CPC) was founded. It took the banner from Sun and shouldered the responsibility of rejuvenating the nation.History has proven that only those who fight for the interests of the people can lead the country to success.Looking back at the past 100 years, it is clear that the Chinese nation swam with the tide of the times, moving forward in the right direction of humanity.Dating back thousands of years, China was among the first countries that shifted from a slave society to feudalism and took the lead toward advanced technologies and outstanding institutions and culture.However, imperial China failed to embrace reform while Western countries overthrew feudalism and emancipated the productive forces after the Renaissance. The failure of the Middle Kingdom was a result of standing still and refusing to make progress by insisting imperial autocracy.The 1911 Revolution was a positive response from China, a result of the country's pioneers applying lessons learned from the outside world. It was also a move from an agricultural society to an industrial society, from autocracy to democracy, and from the emperor's courtyard to the home of ordinary people.But it failed to establish a modern system to eliminate long-standing malpractices and push forward the country's development. China was mired in civil wars and foreign invasions in the first half of the 20th century before the mantle of leadership was handed over to the CPC.Looking to the future, the Chinese people have realized they cannot rest on their achievements. They need to be vigilant against unexpected changes and learn from advanced civilizations with open minds. They must exert effort for domestic economic construction rather than seeking world hegemony.The rejuvenation of the Chinese nation will be a long and difficult process, and development still deserves to be a top priority.Although China has become the world's second largest economy, it remains a developing country, and its GDP per capita ranks only about 100th in the world. Poverty and backwardness still can bee seen in many parts of the country.And the ancient feudal tradition, including the rule of man in certain areas, is still one of the major obstacles hindering China from realizing its modernization goal.During his speech entitled "The Path to China's Future" at Britain's renowned Royal Society in June, Premier Wen Jiabao said, "China was long under the influence of feudalism. After the founding of New China, the country went through the turmoil of the decade-long Cultural Revolution. Since China opened itself, some new developments and problems have occurred."Promoting democracy, improving the legal system and strengthening effective oversight of power remains a long and arduous task for the nation.To commemorate the 1911 Revolution, with a keen sense of responsibility and democracy, people will spur social progress. The more the people participate in social management and public affairs, the greater the momentum there will be to sustain social progress.As for China's development, worldwide observers need to take a more patient and milder attitude.It is better to bear in mind that China feared no difficulties in the history and is pushing forward the reform and opening up with greater resolve.China has conformed with the general situation of the world and the universal values of humanity and is on its way to becoming a modern and progressive country that seeks common development and interests with other countries.One hundred years after the revolution, China is again at a crucial point. The world is undergoing fundamental changes, while scientific and technological revolution and economic globalization are progressing every day. With the financial crisis and other problems, the future of the world is uncertain.Only by swimming with the tide of the times can China achieve complete rejuvenation and make greater contributions to humanity.

WASHINGTON, Dec. 22 (Xinhua) -- The journal Science on Thursday chose the HPTN 052 clinical trial, an international HIV prevention trial as the 2011 Breakthrough of the Year.The study found that if HIV-infected heterosexual individuals begin taking anti-retroviral medicines when their immune systems are relatively healthy as opposed to delaying therapy until the disease has advanced, they are 96 percent less likely to transmit the virus to their uninfected partners. Findings from the trial, first announced in May, were published in the New England Journal of Medicine in August.The study was funded by the U.S. National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health."The HPTN 052 study convincingly demonstrated that anti- retroviral medications can not only treat but also prevent the transmission of HIV infection among heterosexual individuals," said NIAID Director Anthony Fauci in a statement. "We are pleased that Science recognized the extraordinary public health significance of these study results."Science's list of nine other ground-breaking scientific achievements from 2011 include:The Hayabusa Mission: After some near-disastrous technical difficulties and a stunningly successful recovery, Japan's Hayabusa spacecraft returned to Earth with dust from the surface of a large, S-type asteroid. This asteroid dust represented the first direct sampling of a planetary body in 35 years, and analysis of the grains confirmed that the most common meteorites found on Earth, known as ordinary chondrules, are born from these much larger, S-type asteroids.Unraveling Human Origins: Studying the genetic code of both ancient and modern human beings, researchers discovered that many humans still carry DNA variants inherited from archaic humans, such as the mysterious Denisovans in Asia and still-unidentified ancestors in Africa. One study this year revealed how archaic humans likely shaped our modern immune systems, and an analysis of Australopithecus sediba fossils in South Africa showed that the ancient hominin possessed both primitive and Homo-like traits.Capturing a Photosynthetic Protein: In vivid detail, researchers in Japan have mapped the structure of the Photosystem II, or PSII, protein that plants use to split water into hydrogen and oxygen atoms. The crystal-clear image shows off the protein's catalytic core and reveals the specific orientation of atoms within. Now, scientists have access to this catalytic structure that is essential for life on Earth -- one that may also hold the key to a powerful source of clean energy.Pristine Gas in Space: Astronomers using the Keck telescope in Hawaii to probe the faraway universe wound up discovering two clouds of hydrogen gas that seem to have maintained their original chemistry for two billion years after the big bang. Other researchers identified a star that is almost completely devoid of metals, just as the universe's earliest stars must have been, but that formed much later. The discoveries show that pockets of matter persisted unscathed amid eons of cosmic violence.
