摘　　要：在开关完全可靠的情况下,研究了由两个不同型、有优先权的部件和一个修理设备组成的冷贮备系统,建立了在部件工作寿命和修理时间均服从一般时间分布的可修模型,并利用Markov更新过程、LS变换、L变换推导出该模型的一些可靠性指标.The cold-storage system composed of two-category components with different priority and a maintenance facility was investigated in the case that the switch was absolutely reliable. A maintainable model of this system was set up where both the service life of components and maintenence period obey the general time-distribution, and several reliability indices of this model was derived by using Markov＇s renewal process, LS-transformation, and L-transformation.
