This structure can effectively reduce the random failure rate; In the case of failure occurence, it can fully protect the process of failure occurence and repair the controller without stoppage.
该结构能够有效地减少控制系统发生偶然故障的概率，并能够在故障发生的情况下，对生产过程提供充分保护和不停机维修控制器。
The motor on the spot is in operation in the random failure period and therefore its failure rate is approximately a constant.
现场使用的电机基本运行在偶然失效阶段，因而其失效率近似为一常数。
