摘　　要：简单介绍了航天器污染的概念,污染对航天器的损害,航天器污染研究的重要性,以及国内外航天器防污染研究概况。着重介绍真空热试验中的污染控制方法。引入航天器自污染的概念,介绍消除航天器自污染的有效办法是真空烘烤。The paper presents the concept of the contamination and it's harm to the spacecraft,shows the importance of the reaserch on the spacecraft contamination.Meanwhile,has a view with the general situation of the contamination control at home and abroad.It introduced emphatically the contamination method in vacuum thermal experiments.It puts forword the concept of spacecraft self-contaminantion.It argues that the vaccum backout is an effective method of eliminating the satellite self-contamination.
