摘要
着重阐明了闸孔相对开度ｅ／Ｈ及相对作用水头Ｈ／Ｈ＿ｐ对流量系数μ＿０的影响．并通过具体数据说明在堰型、闸门型式、位置及平板闸门切口方向一定的情况下，闸门相对开度ｅ／Ｈ及相对作用水头Ｈ／Ｈ＿ｐ均为流量系数μ＿０的主要影响因素．同时用最小二乘法得出流量系数μ＿０与闸孔相对开度ｅ／Ｈ的关系式呈双曲线型，而不是直线方程．
This article explains that the discharge coefficient for steady free out flow under a highdam spillway gate is mainly influenced by relative gate opening and relative head On thebasis of experimental study a relationship between discharge coefficient po and relative gateopening H developed. The discharge coefficient formula obtained is not a rectilinear equationbut a hyperbolic one.
