standby unit meaning in Chinese

备用部件
备用机组

The eigenvalue of a repairable system with a deleriorating standby unit under common - cause failure and critical human error
在常规故障和临界人为错误条件下具有易损坏储备部件可修复系统的解的特征值
It is shown that , for the unit operating online with any life distribution , the total life length of the cold standby system is stochastically equal to , stochastically larger than , larger in expectation than and larger in increasing convex order than the total life length of the warm standby one if the standby unit is exponential , nbu , nbue and nbuc distributed , respectively
证明了如果在线工作的元件的寿命分别具有指数分布、 nbu分布、 nbue分布和nbuc分布，则冷储备系统的寿命长度随机等于、随机大于、平均大于和依递增凸序大于热储备系统的寿命长度。
