The result show that the position of free surface is higher because of frusta of brake, especial obvious in the head of frusta of brake; flux coefficient and pressure on dam are quite influenced by type of frusta and 3 A type frusta of brake relative to 2 type frusta of brake has bigger flux coefficient and smaller pressure on dam; Obvious influence of ability of discharge flow for different ratio of thickness of frusta and breadth of brake and pressure on dam reduces with increasing ration of thickness of frusta and breadth of brake, while bigger flux coefficient is obtained when tlb = 0.2.(7)The 3D free surface turbulent model established in the paper is comparatively well and truly simulates 3D flow over spillway with frusta of brake and series waterpower computation can be completed aim at different type of dam, type of frusta and disposal on the dam and different water height on peak of

结果表明，闸墩河海大学博士论文的存在抬高了水面线的位置，其中在闸墩头部尤其明显；墩型对流量系数和坝面压力影响较大，3A型闸墩相对于2型闸墩具有更大的流量系数和更小的坝面压力：不同的墩厚闸宽比t/b对泄流能力也将产生显著的影响，随着墩厚闸宽比的增加，坝面压力降低，而当t/b二0.2时溢流坝具有更大的流量系数。7本文建立的三维自由面湍流场模型能够比较准确地模拟带闸墩溢流坝三维过坝水流湍流场，可以针对不同的坝型、墩型、坝面布置形式以及不同的坝顶水头完成系列水力计算，为泄水工程建筑物的设计提供可靠的分析依据

On the basis of analyzing detailedly the correlative conclusions of the extreme value problem of two variable Function , this paper extends the essential condition and sufficient condition to multi-variable function by using the Taylor Formula 、Quadratic Form 、Hesse Matrix and so on,and gives a method to judge the extreme value of point whose vice-derivative doesn't exist by utilizing Lagranges theorem ,so that compensates for the blank above ,which turns idea that solve the extreme value of multi-variable function problem one by one into realities.

摘要本文在对二元函数极值问题的相关结论进行分析的基础上，用泰勒公式、二次型、海赛矩阵作为工具，将二元函数极值的必要条件和充分条件推广到多元函数的情形，而且还利用拉格朗日中值定理找到了一个判别不可导点处极值的方法，从而弥补了多元函数不可导点处极值无法判断的空缺。因而，使得用穷举判断的方法来解决多元函数的极值问题这一思路成为现实。
