| 摘 要： | 针对许多装备维修时间服从或近似服从对数正态分布,从对数方差已知或未知两种角度,在控制单方或双方风险的基础上,提出了维修时间均值的检验方法,并通过实例验证了检验方法的实用性。

| Abstract: | At most time,the maintenance time of equipments is subordinated to the log-normal distribution.Under the control of unilateral risk and both sides,the test of maintenance time mean was put forward on condition of log-variance known or unknown,which had been demonstrated effective by living example. |
