摘　　要：简要阐述空间粉尘的定义、来源、空间分布状况及与航天器发生碰撞概率,并从空间粉尘与航天器外表材料交互作用角度,综述空间粉尘环境因素对热控涂层、高温热管、光学材料、太阳电池和绝缘隔热层影响的国内外研究动态.地面模拟试验表明,空间粉尘高速撞击下对这些材料与元器件会产生不同程度的损伤.The definition, sources and distribution of the space dust particles, as well as the probability for the dust particles to collide with external materials on spacecraft, were expounded. The research state on effects of space dust environment on thermal materials, solar cells and multi - layer insulation blankets was described in terms of the interaction of space dust environment with materials. The ground - based simulation tests demonstrated that the space dust collision could result in the damage of the above materials and elements to different extent.
