摘　　要：本文首先将各类具有网状结构的管网描述成具有整体拓扑性质和个别特性的类拓扑图;其次提出了由类拓扑图生成扩展三角形网的一个快速转换方法;最后给出了一个基于该转换方法的生成类拓扑图等值线的有效算法。所有实验结果均符合实际情况和要求且令人满意。In this paper a similar-topological graph(STG)which has entire topological feature and individual property is presented to describe pipe nets with netted structure.A fast efficient transfor- mation method is offered to generate an expanded triangle net(ETN)from STG.An efficient algor- ithm based on the transformation method for drawing STG contour lines is given.All the experimental results obtained correspond with both our demands and the real condition of the pipe net and seem satisfactory.
