| 摘 要： | 在总结目前推求单位线方法的基础上，提出了一种改进的优化方法－－约束最小二乘法。它通过Ｗｉｎｄｏｗｓ平台上的可视化编程，不震拟定初始单位线和试错，就能快速准确达到单位线的最优适配，并能够在计算机上实现推求和修匀单位线。

An Optimum Seeking Method of Least Squares with Constrain for Unit Hydrograph |
| |
| Abstract: | Based on the summarization of merits and demerits of exist seeking unit hydrograph methods,this paper presents a modified optimum method named method of least squares with constrain.It need not draw up original unit hydrograph and trial-and-error by making program in windows system.It can optimally fit unit hydrograph quickly and accurately and carry out seeking and smoothing unit hydrograph together in computer. |

| Keywords: | unit hydrograph least squares with constrain smoothing visual program |
