摘要
导出了非连序样本下，马氏权函数法（适用于Ｐ－Ⅲ型分布）参数估计公式．在不偏性、有效性的标准下，统计试验结果表明，推导的非连序样本下的计算公式是较为有效的，且拓宽了马氏权函数法的使用范围。
The weighted function moments method is one of the principal methods to estimate the parameters of P-Ⅲ distribution in China, but it can only be applied insimple hydrological series. The formulae of parameters With historical flood series of above method have been derived in the paper. Based upon the Monte-Carlo experimentsthe results of the unbiasness and efficiency of the parameters and design flood valuesshow that above formulae are effective, so the applied scope of weighted function momentS method is expanded in the paper.
