摘　　要：宇航电绝缘材料是深空探测器电信号传递和作用的界限,评估宇航电绝缘材料的环境适应性是材料选择,绝缘设计及工艺处理过程中需要考虑和优化的项目。本文从材料电绝缘性能关联的环境因素入手,介绍了深空辐射环境、热环境、气体环境及颗粒物环境及其效应,给出了深空环境适应性评估流程及验证项目及方法,为宇航电绝缘材料的选用和评估提供参考。Aerospace electrical insulation materials are the boundaries of electrical signal transmission and effect for the deep space explorers. Evaluating the environmental adaptability of aerospace electrical insulation materials is need to be considered and optimized in the process of material selection,insulation design and process treatment. Starting with the environmental factors related to the electrical insulation properties of materials,this paper introduces the deep space radiation environment,thermal environment,gas environment and particle environment and their effects. Then the evaluation process, verification items and methods of deep space environmental adaptability are given,which provides a reference for the selection and evaluation of aerospace electrical insulation materials.
