摘　　要：针对整机贮存期内的区间型定期检测数据,提出系统贮存可靠度近似置信下限的Bootstrap评估方法,利用该方法对系统贮存期进行了综合分析。结果表明,该方法评估精度满足工程应用要求,应用该方法计算系统贮存期近似置信下限比常用的贮存期综合方法更为精确。Aiming at the grouped data of the equipments in the storage period, the Bootstrap estimate method of approximate confidence lower limits of system storage reliability was proposed, we analyzed the system storage period in this method. From the result of the illustration computation, the estimate precision is satisfied with the demand of the engineering application; the estimation of the approximate confidence lower limits of system storage period calculating by Bootstrap method is more exact than the one calculating by the synthesis method of system storage period generally using in project.
