Empirical Bayes estimates of steady-state availability in exponential distribution model;2. Using vector Markov process theory and Laplace transform method,we obtain the Laplace transform of the reliability,the mean time to first failure,the steady-state availability and the steady-state failure frequency and so.

利用向量Markov过程理论和Laplace变换的方法，求出了系统可靠度的Laplace变换，系统首次故障前平均时间的表达式，系统的稳态可用度和稳态故障频度等可靠性指标；此外，还通过数值比较考察了系统参数对系统稳态可用度的影响，并对系统进行了效益分析。

In the document requests clearly, this system's some functions: If the arms locker or the ball medicine-chest are destructed contrary opening, this system auto-alarm; The police overtime will use the gun, the system to send the short note automatically to the police handset on, the reminder will return the gun; If this police returns the guns not on time, then after certain time limit, the information automatic transmission sub-bureau "110" the warning center,"110" will supervise it by the sub-bureau to return the gun as soon as possible; If the sub-bureau "110" has not processed in the scheduled time, the city bureau "110", the city bureau public security branch, the supervisor team will simultaneously receive the alarm message.

文件中更清楚地要求，该系统的一些功能：如果枪柜或弹药柜遭到破坏违规开启，该系统会自动报警；民警超时用枪，系统会自动发短信到民警手机上，提醒还枪；如果该民警不按时归还枪支，则一定时限后，信息会自动发送到分局"110"报警中心，由分局"110"督促其尽快还枪；若分局"110"在规定时间内没有处理，市局"110"、市局治安科、督察队会同时收到报警信息。

After that, The component of the residential heating and meterage system is analysed and some useful conclusion for instructing the design of it have been presented.
