| 摘 要： | 为方便快捷地查找出氧碘化学激光器故障发生的原因，以氧碘化学激光器常见故障为例，建立了其功率失常的故障树模型，用最小割集理论按下行法对模型进行了定性分析和定量分析。分析表明:氧碘化学激光器7个子系统中，碘供给子系统的可靠性最低，氯气供给子系统次之，这与实际情况相符。计算出的氧碘化学激光器出光不正常发生概率为3.99%，其可靠度为96.01%。

| Abstract: | The paper establishes a fault tree model for chemical oxygen iodine laser(COIL) considering power abnormity as its peak affair of fault, and then makes down-way qualitative analysis and quantitative analysis with the minimum cut-set theory. It is indicated that the reliability of iodine supply subsystem is minimum, followed by the chlorine supply subsystem, in the seven subsystems of COIL. The probability at which the power of COIL is abnormal is 3.99%, that is, the reliability of laser is 96.01%. |
