说明：  基于贝叶斯网络的可靠性评估，输入个元件的故障率数据，计算各元件的条件概率，建立贝叶斯网络，贝叶斯推理，得到系统可靠工作情况下各元件的工作概率。
(Based on the reliability evaluation of Bayesian network, input the failure rate data of components, calculate the conditional probability of each component, establish Bayesian network, Bayesian reasoning, and obtain the working probability of each component under the condition of reliable operation of the system)
