摘　　要：对指数分布无失效数据的失效率，在先验分布为Ｇａｍｍａ分布Ｇａｍｍａ（１，ｂ）时，给出了多层Ｂａｙｅｓ估计，从而可以得到无失效数据可靠度的估计。并结合实际问题进行了计算。Abstract In this paper, when prior distribution of the failure rate is in form of Gamma distribution Gamma(1,b), hierachical Bayesian estimation of the failure rate in exponential distribution has been come out from zero failure data. Then the reliability estimation of zero failure data are come out, finally calculation is performed regarding to practical problem.
