摘要
该文根据瑞安市 1 965～ 1 997年降水自记记录 ,通过适当的概率模式对暴雨强度抽样频数分布进行拟合 ,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 .利用最优化法进行非线性超定方程组的求解 ,从而实现对暴雨强度公式中参数的估计 .
WT5BZ]Based on the 33 year (1965 1997) automatically recorded precipitation data of Ruian city, the frequency distribution of storm intensity is discussed by using probability models. The i t T table that describes the relationship of storm intensity, rainfall duration and return period is presented. Furthermore, Parameters in the storm intensity formula are estimated by using the optimal solution to solve the super nonlinear coupled equation.[WT5BZ] [WT5HZ]
