The results show that the minus value and fluctuation of unit hydrograph can be mitigated and the error of observed discharge can be withstood using the robustified ridge estimation 最后采用抗差岭估计来推算单位线,该方法既可以解决共线性的问题,也可以抗御粗差的影响,得到比较稳定的单位线。
According to the collected data in first two years , the study tried to simulate the runoff model by the instantaneous unit hydrograph theory and analyzed the data , the results were shown as follows 本文系以瞬时单位历线为基础,进行迳流历线之模拟,同时将分析整理前两年之观测资料,所得之初步结果列述如下:
