中文说明：贝叶斯推断（BAYESIAN INFERENCE）是一种应用于不确定性条件下的决策的统计方法。贝叶斯推断的显著特征是，为了得到一个统计结论能够利用先验信息和样本信息。本程序可以利用少量观测数据进行贝叶斯推断，实现系统可靠性分析的好例子。
English Description：

The salient feature of Bayesian inference is that prior information and sample information can be used to get a statistical conclusion. This program can use a small amount of observation data for Bayesian inference to achieve a good example of system reliability analysis.
