微重力科学与应用研究（上）

空间微重力环境的独特物理现象对航天器各系统均产生无法回避的影响，在型号研制中正确计入微重力效应是航天事业发展中的一个重要研究领域。在现阶段，航天器发动机再启动相关的微重力研究以及载人航天防火安全相关的微重力研究应当引起人们的高度重视。随航天事业的发展，微重力效应问题日益会严重起来（结构动力学、耦合动力学、多相流温控、低重星球场着陆撞击……），进行深入广泛的微重力效应研究对保证航天器飞行任务完成有着不应忽视的作用     

论贾谊的教育思想

贾谊是我国古代比较系统地提出教育思想的人之一。他的教学内容以儒家礼教为中心，以道德教育为目标，从而建构了他的教育思想的基本框架。他首倡胎教，他总结的一些经验和理论与现代的胎教思想不谋而合。他强调环境对教育的重大影响，认为良好的环境有利于提高品德，增长学识。在教与学这个矛盾中，他强调教师的积极主导作用，并明确指出了教师的职责和任务。

A Geosynchronous Orbit Search Strategy

Since more than 10 years there is evidence that small-size space debris is accumulating in the geosynchronous orbit (GEO), probably as the result of breakups. Two break-ups have been reported in GEO. The 1978 break-up of an EKRAN 2 satellite, SSN 10365, was identified in 1992, and in 1992 a Titan 3C Transtage, SSN 3432, break-up produced at least twenty observable pieces. Subsequently several nations performed optical surveys of the GEO region in the form of independent observation campaigns. Such surveys suffer from the fact that the field of view of optical telescopes is small compared with the total area covered by the GEO ring. As a consequence only a small volume of the orbital element-magnitude-space is covered by each individual survey. Results from these surveys are thus affected by observational biases and therefore difficult to compare. This paper describes the development of a common search strategy to overcome these limitations. The strategy optimizes the sampling for objects in orbits similar to the orbits of the known GEO population but does not exclude the detection of objects with other orbital planes. A properly designed common search strategy clearly eases the comparison of results from different groups and the extrapolation from the sparse (biased) samples to the entire GEO environment.     

SPACE LIFE SCIENCE IN 2000-2001

Chinese scientists studied some of the problems in the field of space life science and achieved success in the area during 2000-2001. Space biological experi ments were carried out in the orbit and the results of ground studies on protein crystallization, space radiation, space motion sickness were introduced in this paper. The influences of simulated weightlessness on the brain-function, the car diovascular, endocrine hormones, immunity, skeletal and muscle systems were presented. In addition, gravity medicine and space environment medicine, as well as countermeasures to space deconditioning, such as the traditional Chinese medicine, were also reported.
