英文摘要：

In order to study the reliability maintenace of varied environment systems, the varying parameter Poisson processes of complex multi-component system at t0, t1,…, tN are discussed in this paper. The independece for different kinds of failure times Xk^n is proved by using strong Markov property. The varying parameter geometric distribution is given, that is, Xk^n～Geometric（pk）. The statisticsal property of geometric distribution is also verified.
