航天器在全生命周期内经历各种各样的环境,用户和工程研制方需要根据任务活动定义所遇到的环境,设计人员则需要根据这些环境对产品的影响进行设计,以满足航天器的功能、性能、可靠性、安全性和环境适应性等要求.文章从环境工程角度分析了环境剖面的制定、分析和环境条件的演化过程,从产品设计角度研究了航天器在任务过程中遇到的各种环境要素,给出了典型的航天器环境要素以及需要考虑的特殊环境,总结了单一环境和组合环境对航天器的典型效应,可为我国航天器设计和试验提供参考.%The spacecraft has to encounter kinds of environment in it's life-cycle.The user and manufacturer shall define the environments according to the mission activities,and the designer shall consider the environmental effects on products to ensure that the function, performance,reliability,safety and environmental worthiness of spacecraft meet the require-ments.Based on the above ideas,the development of environmental conditions and the evolu-tionary process of environmental profile for spacecraft are analyzed from the perspective of environmental engineering.The encounter environmental factors of spacecraft in the missions are discussed from the perspective of product design.The single environmental factor effect and combined environmental factor effects on spacecraft are given which can provide a refe-rence for spacecraft design and test.
