摘　　要：介绍了间歇故障的概念,对间歇故障的背景和产生原因以及间歇故障诊断问题的研究意义进行了分析,以间歇故障的成因、幅值特性和不同时刻发生故障之间的相关性等为依据,对间歇故障进行了分类.然后对间歇故障诊断的研究现状进行了概述,把目前间歇故障诊断的方法大体分为定性分析和定量分析两大类,并对每一类现有的方法进行细分,对每种方法的基本思想、优劣特点和适用条件进行了概述和讨论.最后探讨了间歇故障诊断研究中亟待解决的问题.The concept of intermittent faults is introduced and the background, cause, as well as research significance of the fault diagnosis problem for intermittent faults are analyzed. Classifications for intermittent faults are provided according to their characteristics such as cause, amplitude and correlations with different time instants. The research status of fault diagnosis for intermittent faults is reviewed in two categories, i.e., qualitative analysis and quantitative analysis methods. The basic ideas, advantages, disadvantages, as well as application conditions of each category are highlighted and discussed. Finally, some open problems of the research on fault diagnosis for intermittent faults are pointed out.
