| 摘 要： | 本文将四阶线性矩检验法引入暴雨频率分布线型的选择,分析四阶线性矩检验法作为暴雨频率分布线型的选择准则的适用性,并与国内外其他4种常用的选优统计量得出的结果进行比较.四阶线性矩检验法的结果表明三参数的对数正态分布与各流域的实测暴雨资料拟合最好,这与其他4种方法的结论基本一致,很好地鏊别了暴雨频率的分布线型,四阶线性矩检验法可以作为检验暴雨频率分布线型选择的方法,四阶线性矩检验法扩展了暴雨线型检验的方法.

| Abstract: | In this paper,fourth-order L-moments method was used in choosing best design storm frequency distribution and its suitability was also analyzed through the comparison with other four methods for the selection of best distribution.The results show that the fourth-order L-moments method is significant if the LN3(three-parameter lognormal) distribution is used as for the study area,this result is same as other four methods.The fourth-order L-moments is a good method in choosing design storm frequency distribut... |
