The magnetic random access memory(MRAM) is a key device for the future computer, information and telecommunication technologies. CAS scientists have recently developed a demo device for a new type of MRAM, which could overcome two bottleneck problems for its development, namely, high energy consumption and low storage density.  相似文献

<正>Since the 20th century,technologies for outer space exploration have developed rapidly,but we still know little about the deep sea on Earth."We know even less about the deep sea than the Moon or Mars",Professor WANG Pinxian from the Chinese Academy of Science once remarked.It means that we are on a relatively low level of scientif ic research about the deep sea,but it also indicates a huge potential in the f ield.1.The manned deep-sea submersible will guide the development of deep-sea exploration technologies The deep-sea exploration technology is a complicated and integrated set of high technology that involve many ST disciplines and can provide methods and instruments for the scientif ic research and resources exploration of the deep sea.It can also promote the development of a variety of general technologies and equipment concerning deep sea exploration.The technology is an essential means to detect resources in the  相似文献

The literature suggests that protection of knowledge from the threat for opportunism is a primary mover for the choice of entry mode.However,the knowledge construct is oversimplified in the literature on entry mode.The combination of different types of knowledge held by a firm reduces the risk of misappropriation and the threat of opportunism is often unimportant in entry mode decisions.Based on these discussions,a new conceptual knowledgebased model of entry mode choice is devoloped.In this model,the kn...  相似文献

The Technology and Engineering Center for Space Utilization, Chinese Academy of Sciences was honored for its outstanding contributions to China’s manned spaceflight program at a special ceremony held in Beijing on December 16, 2011. The Center, established in 2011 to replace its predecessor, the General Establishment of Space Science and Application of CAS, has successfully completed the test missions of the Shenzhou spacecraft series and the Tiangong-1 target spacecraft. It has also developed nearly 300 sets of payloads by far to serve earth observation,  相似文献

This paper addresses the development of an optimal robust control algorithm for the systems with large parameter perturbation. The resulting control system may provide the satisfactory optimal robustness properties in the sense of a modified linear quadratic cost function. The related optimal gain matrix of the Controller for the systems with the defined upper bound of uncertainties could be designed to the minimal degrees via using the approaches to design of optimal robust control as developed here. Finally, the numerical examples are given to describe the applications and results of the proposed techniques.  相似文献

A method for the determination of trace chromium(Ⅳ) in water by frow injection analysis with an amperometric detector has been developed. With a carrier solution of 1% NaCl and 0.1N HCl, chromium(Ⅵ) is determined in small sample volumes at a flow rate of 4.0mL/min, The applied potential is 100mV (vs. SCE). This method provides a detection limit of about 0.2μg/l, with a relative standard deviation of 1.6％. The method can be used for determination of chromium(Ⅵ) in natural water and industrial waste water.  相似文献

In cooperation with colleagues from the China Pharmaceutical University over the past 15 years, researchers from the Shanghai Institute of Materia Medica (SIMM), a pharmaceutical research arm of CAS, have developed a new injection of acehytisine hydrochloride as a natural medication against heart rhythm disorders. The drug was officially approved on August 22, 2005 by China's State Food & Drug Administration (SFDA) as a new and marketable pharmaceutical for clinical therapy.  相似文献

On 13 December 2006,the Shanghai Higher People's Court rendered its final ruling in a case of dispute arising from infringement of copyright in computer software,holding that the plaintiff specially designed an output document for- mat for bundling its own developed application for use in the product it has made,and this act had gone beyond the scope of technological protection measures provided for in the Copyright Law,and that defendant's act of circumvent- ing the output data document format of said software was not an infringement.This is the first case of using technologi- cal protective measure for product bundle in China ever since the amended Copyright Law entered into force in 2001.The ruling is of far-reaching significance in guiding the courts to hear similar cases and for the orderly development of the related industry in China.  相似文献

The activities of the government can be described as reporting the feelings of the people (receiving infor-mation), making policies (processing information) and issuing government orders (sending out information). This is a typical course of information processing. If we can successively trail and scientifically measure this information course, we will be able to appraise the performance of the government in a scientific way. The development of government informatiza-tion and e-government is providing such a kind of appraisement for the government. The paper mainly discusses the possi-bilities of informetric analysis of the e-government. Methods for such analysis are also described.  相似文献

Ⅰ. Have a Clear Understanding of the Situation, Unify our Thinking and Explicitly Define the Guidelines for Running CAS in the New Era The first year of the new century witnessed a range of important events taking place in China and around the world, including China's accession to WTO, the non-official summit of APEC held in Shanghai and Beijing's successful bidding for the 2008 Olympiad.These are sufficient to testify to a global recognition of China's achievements in economic and social development. The "three-represents" theory1 was advanced as the guiding principle for the building of the Chinese Communist Party in the new century.  相似文献
