摘　　要：介绍了一种绘制给水管网等压线的算法———三角形网格法。把离散的节点连接成不规则的三角形网格，在三角形网格上追踪等压点，最后将等压点用光滑曲线连接，即可给出等压线。该算法可精确地绘制出等压线。n this paper an algorithm manipulation for isobar drawing of pipe network called trianpulation algorithm is introoduced.Discrete nodes are linked to make a triangulation.Isobaric points are traced in this triangulation.Isobar can be drawn by linking isobaric points with smooth curve.This algorithm can draw isobar accurately.
