中国返回式卫星的搭载任务—空间材料科学试验

１９８７年以来，为充分利用中国返回式卫星的剩余载荷能力，有计划地以搭载形式进行了一系列空间科学和技术试验，取得了较好的结果。文章简要地介绍在空间材料科学试验方面取得的成果。     

不锈钢、钛合金导管高频钎焊工艺方法的改进

高频钎焊焊接方法在国内外进行研究的院校和公司相对较少，是一项较新的钎焊方法。国外在此项焊接工艺的研究和应用走在世界的前列。国内一直处于不断摸索和改进的过程中，焊接过程始终存在一些问题。通过本课题技术研究和相关的试验，详细地介绍了高频钎焊设备、工艺方法和高频钎焊工艺参数确定等方面的应用。     

Regional Centres for Space Science and Technology Education and ICG Information Centres affiliated to the United Nations

Based on resolutions of the United Nations General Assembly, Regional Centres for Space Science and Technology Education were established in India, Morocco, Nigeria, Brazil and Mexico. Simultaneously, education curricula were developed for the core disciplines of remote sensing, satellite communications, satellite meteorology, and space and atmospheric science. This paper provides a brief summary on the status of the operation of the regional centres with a view to use them as information centres of the International Committee on Global Navigation Satellite Systems (ICG), and draws attention to their educational activities.     

2012–2014 China's Earth Observation and Earth Science Development

Human beings are now facing global and regional sustainable development challenges.In China, Earth observation data play a fundamental role in Earth system science research. The support given by Earth observation data is required by many studies, including those on Earth's limited natural resources, the rapid development of economic and social needs, global change, extreme events, food security, water resources, sustainable economic and urban development, and emergency response. Application operation systems in many ministries and departments in China have entered a stage of sustainable development, and the State Key Project of High-Resolution Earth Observation Systems has been progressing since 2006. Earth observation technology in China has entered a period of rapid development.     

Electrostatic accelerometer with bias rejection for gravitation and Solar System physics

Radio tracking of interplanetary probes is an important tool for navigation purposes as well as for testing the laws of physics or exploring planetary environments. The addition of an accelerometer on board a spacecraft provides orbit determination specialists and physicists with an additional observable of great interest: it measures the value of the non-gravitational acceleration acting on the spacecraft, i.e. the departure of the probe from geodesic motion.     

大力开展继续教育不断加强航空人才培养

科技、人才、教育是21世纪航空工业发展中举足轻重的三要素。科技的发展靠人才,人才的培养靠教育。继续教育作为教育的一部分,是培养高素质人才的重要途径。继续教育为我所培养了科研、生产、管理急需的人才。实施继续教育登记制度,是强化继续教育管理,激励专业技术人员主动参加继续教育的一种手段,有利于人才的培养和成长。     

采暖空调技术改造对策综合分析

现代系统科学的发展及其哲学意义

从哲学视角论述了现代系统科学的产生与发展，探讨其与马克思主义辩证只唯物史观的内在联系，并且从博大精深的古老中华文化里探究系统观念之渊源。     

中国返回式卫星的进展

从１９７５年至１９９４年中国研制成功了ＦＳＷ－Ｏ、ＦＳＷ－１和ＦＳＷ－２三种型号的返回式卫星。ＦＳＷ－０卫星９颗发射和返回均获成功;ＦＳＷ－１卫星５颗除ＦＳＷ－１－５卫星返回失败外其余均获成功;ＦＳＷ－２卫星２颗发射和返回均获成功。卫星的起飞质量从ＦＳＷ－０－１的１７９０ｋｇ增加到ＦＳＷ－２－２的２７６０ｋｇ,轨道运行时间从ＦＳＷ－０－１的３天增加到ＦＳＷ－２－１的６天。卫星的服务业务不断扩大,ＦＳＷ－２已发展成为一种兼有应用、空间科学试验和技术试验功能的多用途卫星。     

微重力流体科学空间实验的分析和设想

本文通过回顾国外微重力空间实验的发展,着重分析研究发展趋向及微重力流体科学在空间材料科学中的地位。基于我们理论和地面实验工作基础,提出对微重力流体科学空间实验的一些设想。最后,我们着重说明为什么把Marangoni对流和液体桥的稳定作为近期重点跟踪课题。
