摘要
对系统进行多项环境和各分系统相互间作用的考核，实现系统的综合环境试验，在给定可靠性评定方案下，验证系统的实际可靠性，是当今一项先进技术，要求较高的技术水平。经多年研究，首先对再入飞行器系统实现了这项试验。从综合环境条件的确定、可靠性评定方案的建立、环境条件的模拟和控制等方面作了介绍，由于技术上的先进性、有效性及复杂性，对此我国宇航界产生了很大兴趣。
It is an advanced technique in our country and abroad to perform system's combined environ-mental reliability test to examine interaction between subsystems underdiffrent environmental conditions,such as:random vibration, noise, temperature, humidity and electric stress. This technique was realizedfor the first time by us after years of research.This paper describes determination of combined environmental conditions, establishment of reliabilityevaluation program, simulation and control of environmental conditions, etc. As the test is advanced, ef- fective and complex in technology, it aroused great interest in aerospace industy of China,
