摘　　要：根据随机过程与统计假设理论 ,针对可修机械系统故障与维修特点 ,阐述了可修机械系统故障数据的随机特性。并根据现有检验分析方法 ,提出了集趋势检验、拟合性检验、有效性检验和指数性检验于一体的综合检验方法 ,用于对故障数据进行检验与分析 ,同时给出了检验程序框图 ,进行了实例分析。In this paper, some models of reliability and statistical test based on the theory of stochastic process and hypothesis, as well as the failure data of repairable systems are described A synthetic test, which can be used for testing the trend, goodness of fit, validity and exponentiablity of failure data is presented The method and diagram of statistical test are also derived A application example for a set of failure data of a diesel engine is discussed

关 键 词：可修机械系统 故障数据 随机特性 综合检验
