摘要：

Based on asymmetric loss function, the estimations and their properties of liquid rocket engine are discussed. The UMVUE and bayes estimator for some lifetime parameters, reliability and hazard function are obtained under entropy loss function. And we prove the estimations with the form of cT+d are admissible. At last, the statistical performances are compared through the MSE based on Monte Carlo simulation study. According to these comparisons, it is suggested that the empirical bayes estimators have high-precision.
