| 摘 要： | 卫星有机材料放气产生的分子污染是卫星在轨污染的重要来源。分子污染会造成敏感表面光学性能退化甚至失效，因此必须进行评估分析。文章对在卫星真空热试验中，采用光学试片进行污染光学效应测试的数据进行了分析，并且与国内外试验数据进行了比对，发现光学试片测得的透过率损失数据较为保守，分析原因是光学试片污染沉积为液滴状，导致散射损失较大。

| Abstract: | The molecular contamination produced by satellite organic materials is an important source of contamination in orbit.It can degradate optical performance and even lead to failure of sensitive surfaces,so its effects must be evaluated.In satellite thermal vacuum tests,optical specimen is used to monitor contamination effects.In this paper,we analyze the experimental data,compare them with those obtained by other authors.It is found that the transmission loss of the optical specimen is greater than nominal va... |
