摘要
本文给出了转换开关完全可靠时，由ｎ个相互独立的指数寿命型元件组成的冷贮备系统，当其中Ｋ个元件的失效率相同，另外ｎ－ｋ个元件的失效率各不相同时，系统可靠性的表达式。此结果是ｋ＝０及ｋ＝ｎ时结果的推广。同时，本文基于元件的分组试验数据。
In this paper, we gave the reliability of standby system consisting of n components with faultlessness switch, when k has the failure rate, respectively, the result given in the paper is the developmemt that of k= 0 and k=n, and also gave the classical exact lower confidence limit of the reliability by the 'LP' ordering method.
