摘　　要：考虑两个具有不同形状和尺度的含弹性参数指数模型,分别从似然比序、反向失效率序和通常随机序对顺序统计量进行随机比较,将似然比序关系推广到反向比例失效率模型.This paper studied the likelihood ratio order,the reversed hazard rate order and the usual stochastic order of order statistics in two heterogeneous exponential samples with a resilience parameter wherein they have both differing scale parameters and differing shape parameters.A likelihood ratio order was built for the maximum of a sample with proportional reversed hazard rates.

关 键 词：失效率序 似然比序 占优序 p-序 成比例反向失效率模型
