摘要
文中运用最小二乘估计、高斯 -牛顿逐次迭代法等数学方法 ,结合实测资料 ,得到了水力计算中常用的 WES剖面实用堰流量系数的计算公式 ,与传统的查图法比较 ,其计算简单 ,而且精度高 。
A new calculating formula of flow coefficient of WES (Waterways Experiment Section)weir is given in this paper by the LES (least square estimation)and Gauss Newton successive interation method combined with measurement data.Compared with traditional chart method,the formula is more simple and accurate,which leads to a popular use in hydraulic calculation.
