导弹系统所承受的环境应力是影响其可靠性的主要因素之一。本文论述了综合环境试验对防空导弹可靠性增长的作用、试验剖面与环境应力的确定、试验中故障判决方法和试验结束方式等一系列试验中遇到的问题，并进行了探讨。 Environmental stress to which missile systems are subjected is one of the major factors that affect their reliability. This article discusses the effects of comprehensive environmental tests on the reliability growth of air defense missiles, the determination of test sections and environmental stresses, the methods of fault judgment and the way of end of tests in a series of experiments, and discusses the problems encountered.
