中文摘要：

将间歇故障误诊为永久故障会导致不必要的停机和过维修的问题，影响战备完好性并造成维修保障资源浪费，故提出了一种间歇故障诊断方法。分析了间歇故障对系统的影响，剖析了间歇故障诊断面临的技术难点，综述了国内外学者间歇故障诊断方法，并对间歇故障失效机理与演化规律、包含间歇和永久故障的诊断模型与方法以及极端环境应力下的间歇故障诊断方法3个方面需要开展的进一步研究工作进行了阐述。该研究为间歇故障诊断，尤其是极端环境应力诱发的间歇故障诊断问题提供了参考。

英文摘要：

If intermittent fault is determined as permanent fault will cause needless shut down and excessive maintenance, make bad influence on operational readiness and waste maintenance support resource, put forward an intermittent fault diagnosis method. Analyze the influence of intermittent fault on system and technical difficulties of intermittent fault diagnosis, and summarize experts＇ intermittent fault diagnosis methods at home and abroad. Then, introduce the further research of intermittent fault failure mechanism and evolution law, diagnosis models of intermittent fault and permanent fault and intermittent fault diagnosis method under extreme environment. The research provides reference for intermittent fault diagnosis, especially for intermittent fault diagnosis problem cause by extreme environment stress.
