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。
On the basis of the afore-said constant failure rate, a reliability test, using constant time or constant number tail cutting scheme, is recommended.
在恒定失效率的假设下，推荐采用定时或定数截尾试验方案在现场进行电机的可靠性试验。
