【摘要】 利用供水管网图形的拓扑矩阵 ,提出了一种在管网水力计算基础上逐级搜寻水源的供水区域和绘制管网等压线的方法。并在AutoCAD2 0 0 0平台上用VBA编程直接调用水力计算结果实现供水区域、供水分界线的图形显示、管网等水压线自动绘制以及管网流量分布的计算更多还原

【Abstract】 A topological based method was developed for determination of source serving districts and drawing pressure contour in multi source networks. A matrix describing topological relationship between lines and joins in the multi source networks was set up for the computer aided analysis. Graph display of source serving districts, dividing lines and pressure contour was performed using VBA based on AutoCAD2000.更多还原
