中文摘要：
基于逐步增加Ⅱ型截尾样本，讨论了某型号液体火箭发动机可靠性指标的Bayes估计及E—Bayes估计。在刻度平方误差损失函数下，给出了火箭发动机寿命分布参数、可靠度函数及失效率函数的Bayes估计及E—Bayes估计。最后运用MonteCarlo方法对各种估计的均方误差进行了模拟比较。结果表明，E—Bayes估计给出的估计精度高。
英文摘要：
Based on progressively type- H censored samples, the Bayesian estimations and E-Bayesian estimations for a kind of liquid rocket motor are discussed. The Bayesian estimations and E-Bayesian estimations for some lifetime parameters, reliability function and hazard function are obtained under the execution of scaled squared error loss function. Finally, the statistical performances are compared through the MSE based on Monte Carlo method. According to these comparisons, it suggests that the derived E-Bayes estimation is more preferable.
