摘　　要：讨论作为时间相依尺度变换的加速寿命模型的特征,给出该模型中次序统计量关于一些随机序封闭的条件.得到NWUT寿命分布次序统计量在加速寿命模型封闭的条件.The characteristics of accelerated life model as time-dependent scale transformation was discussed. The closure conditions of order statistic in this model were given with respect to some stochastic orders. The closure conditions of order statistic of NWUT life distribution in accelerated life model were obtained.
