介绍了对材料有重要影响的空间辐照环境 ,并利用地面模拟设备对某些遥感光学材料在空间辐照环境下的行为进行研究。结果表明 ,以质子、电子和太阳紫外线为代表的空间辐照环境在光学材料中产生表面剥蚀、着色、诱发表面污染和充放电等效应 ,从而使光学材料的性能在不同程度上退化 The space radiation environment which has important influence on the materials was introduced and the ground simulation equipment was used to study the behavior of some remote sensing optical materials in space radiation environment. The results show that the radiation environment represented by proton, electron and solar ultraviolet radiation has the effects of surface ablation, coloration, induced surface contamination and charge-discharge in optical materials, so that the properties of optical materials are degraded to some extent
