摘　　要：考虑第k-1个元件在时刻t或时刻t以前失效的条件下,k-out-of-n系统仍在工作时的剩余寿命,得到了剩余寿命的一些年龄性质.The residual life of a k-out-of-n system which still functions with probability one is investigated, given that the （k-1）th compnents has failed at or before time t〉O. Some aging properties are obtained.

关 键 词：k-out-of-n系统 剩余寿命 协作系统 随机序 似然比序
