摘　　要：讨论了在熵损失下定时截尾数据的Bayes估计问题,将无失效数据看作逐次定时截尾试验的结果,进而得到无失效数据的Bayes估计,利用相关定理证明该估计是容许的。通过数值例子,进一步说明所得估计的合理性。In this paper, the Bayes estimation of type- I censored data was discussed, and based on this result, the Bayes estimation of zero-failure data was obtained with considering the zero-failure data as the time type- I censored data. With correlational theorem the admissibility of the estimation was proved. Finally, the rationality of the estimation via numerical example was accounted.
