摘　　要：文章梳理了面向航天器总体设计的空间辐射效应分析技术现状,重点归纳了航天器空间辐射效应分析中需关注的总剂量效应、位移损伤效应、单粒子效应分析的要素、分析方法及软件工具,并结合近年来国际上空间辐射环境模型的最新进展,就辐射环境动态变化认知、在轨辐射风险表征、陌生轨道区域辐射环境影响分析等方面提出国内空间辐射效应分析技术的不足及后续发展建议。The space radiation effect analysis technology in the spacecraft design is reviewed and the main elements of the space radiation effect analysis technology are shown to include the methods and the software tools,the total ionizing dose effect,the displacement damage effect,and the single event effect.According to the latest progress in the space radiation environmental model,further development directions of space environment effect analysis technology are proposed such as the recognition of dynamic variations of radiation environment,the on-orbit radiation risk characterization,and the analysis of the radiation impact in unfamiliar orbits.
