| 摘 要： | 广义极值分布频率曲线,也可采用均值、变差系数和偏态系数等三个统计参数来进行计算。通过建立离均系数表,可以方便地进行频率分析计算。现以澧水某站年最大流量系列为例,采用广义极值分布的适线法进行频率分析计算,成果表明广义极值分布具有一定适应性。

| Abstract: | The frequency curve of generalized extreme-value distribution may also be calculated using the three statistical parameters of mean value,variation coefficient and skewness coefficient.Through establishing the table of frequency factor for this distribution,frequency analysis and calculation can be carried out conveniently.A series of annual maximum discharge of a station on Lishui River was taken as an example,we carried out frequency calculation of GEV with frequency curve fitting method.The results show ... |
