摘要
讨论了泊松过程的性质,研究了冲击次数服从泊松过程、损坏是可加的冲击模型,并给出了期望损坏,从而为评估系统寿命提供了依据。
This paper discussed the properties the Poisson process and studied the shock model with the impact number obeying the Poisson process, then gave the the expectation of the damage system so as to provide the basis for evaluating system life.
