Media Time Between Faults(MTBF )

用法例句

Whenever n is given, we can obtain the exact formulas of the system reliability (or its Laplace transformation) and the system MTTFF (mean time to first failure).

利用本文引进的广义转移概率定义导出了系统的状态转移概率，当ｎ已知时，我们能够获得系统可靠度的Ｌ－变换和首次故障前的平均时间的精确表达式。

Assuming that the working time and repair time of each component are both exponentially distributed and that each component after repair is as good as new, we derive the exact expressions of the reliability and MTTFF of the repairable system.

研究了ｎ中取相邻ｎ－１好的直列可修系统，假定每个部件的工作时间和维修时间都是指数分布且故障部件能“修复如新”时，求出了该系统的可靠度和首次故障前的平均时间等可靠性指标的精确表达
