摘　　要：利用北京卫星环境工程研究所拥有的各种规模的空间环境模拟器在进行真空热试验时,测量卫星表面返回质量流密度和发射质量流密度,通过加文(GarWin)方程组来确定轨道卫星的污染预估,从而解决了当前型号研制中污染控制的问题。The contamination of orbiting satellite is predicted by GarWin Equation.The density of mass flux is measured returning to and emitting from the satellite surface during environment simulation test of various spacecraft.There are various kinds of space environment test facility in Chinese Academy of Space Technology.It is tried to solve the practice of contamination control engineering during design and development of space program.

关 键 词：真空热试验 分子流 轨道卫星 污染预估
