摘　　要：基于航天材料在轨将遭遇多种空间环境的作用且不同空间环境对航天材料的损伤存在一定的关联性,本文首先对航天材料的空间环境及效应进行了介绍,接着对真空、温度、微重力、等离子体、粒子辐射、太阳电磁辐射、空间大气、空间碎片及微流星体、空间污染、空间动力学、腐蚀及空间生物等环境对航天材料的损伤机制及不同损伤机制之间的关联性进行了研究,最后对需要进一步研究和关注的方向进行了讨论并给出了发展建议。Spacecraft materials will encounter different space environments in space and there are relevance between damage mechanism of different space environments on spacecraft materials. In this paper,space environments and their effects on spacecraft materials are introduced firstly,then damage mechanism and their relevance of space environments such as vacuum,temperature,microgravity,plasma,particle radiation,solar electromagnetic irradiation,space atmospheres,space debris and micrometeoroid,space contamination,spatial dynamics,erosion,space biology,etc,on spacecraft materials are studied. At last,the developing trends and problems of the spacecraft materials are commented.
