摘　　要：提出一种新型求取水轮机模型综合特性曲线中随机插值点的效率方法,将水轮机综合特性曲线中等效率η线类似为等高线,利用VB处理数据,将采样点单位统一后构建Delaunay三角网,应用三角形内插法可较精确地求得综合特性曲线中各随机插值点的效率。A new method for getting efficiency of random interpolation points in combined characteristic of model turbine is proposed.The efficiency curves are taken as the contour lines.Then the unit unified sampling points with VB technique are used to construct Delaunay triangular mesh.Finally,the efficiencies of random interpolation points can be calculated accurately by using triangle interpolation algorithm.
