| 摘 要： | 根据暴雨强度资料,采用皮尔逊Ⅲ分布模式对暴雨强度频率分布进行拟合,并由此编制反映暴雨强度、历时、重现期三者关系的i-t-T表。在对暴雨强度公式中参数确定时,引入基于非线性最小二乘法原理的数学优化技术,并给出了在Matlab环境下的实现过程。

| Abstract: | Based on the Storm Intensity data,the frequency distribution of storm intensity is discussed by using Pearson-Ⅲ frequency distributions models.The i-t-T table describes the relationship of storm intensity,rainfall duration and return period is presented.The mathematical optimization technique,which is based on nonlinear least square principle,is applied in determining the parameters in the storm intensity formulas.The implementation is given in the MATLAB environment. |
