摘　　要：将威布尔分布数据转化为均匀分布数据,利用平均剩余寿命构造样本矩,得到了在定数截尾样本下三参数威布尔分布的矩估计方程.Based on censored samples, the problem of moment estimation of the three-parameter Weibull distribution is discussed. Mean residual lifetime is used to constructed sample moment. With the method of transformation, the modified moment equation is derived. Especially, together with geometric mean, we set up the first equation, which makes the outcome more precise.
