摘　　要：研究了n个独立同分布元件构成的n取(n-k+1)系统的条件平均剩余寿命,即在时刻t时至少有j个元件失效的条件下系统的平均剩余寿命,并得到了几个该平均剩余寿命的性质。We study a mean conditional residual lifetime of the(n-k1)-out-of-n system consisting of nindependent and identically distributed components.It is assumed that at time t the system at least j th components has failed and obtain several of its properties

关 键 词：n取(n-k+1)系统 平均剩余寿命 失效率
