摘　　要：给出了单参数指数分布定时截尾样本场合下步加试验TFR模型下参数的修正极大似然估计,并通过模拟表明修正的极大似然估计的精度高于极大似然估计。We give the modified maximum likelihood estimator of parameters of exponential distribution with TypeⅠCensoring Sample Size based on tampered failure rate model under step-stress accelerated life testing, and through the Monte-Carlo simulation show that the modified maximum likelihood estimation accuracy is better than the maximum likelihood estimation.
