| 摘 要： | 对线性矩法与概率权矩法进行了分析，认为线性矩法与概率权矩法对统计参数估计的结果是一致的，它们之间具有同解关系，其计算结果略存在的差异乃是由于采用不同近似公式的计算误差所致。

| Abstract: | The study shows that the results of estimating the statistic parameters by L moments are same as that by probability weighted moments (PWM). Both methods have the relation of same solution. The small difference of both results is due to the error of calculation by using different formulas of approximate calculation. |

| Keywords: | L moments probability weighted moments the relation of same solution |
