摘　　要：目前,工程中大量存在已知离散点上函数的数值要求绘制其等值曲线的问题。本文给出了一种新的搜寻和对等值点重新排序的方法,对等值曲线具有分枝、闭合,甚至为几条分离的等值曲线的情况给出了满意的解决方法。In engineering, it is generally required to draw a group of isopleth by the known function values of scattered points. It is suggested that synthesis the two methods of scanning and reordering together to draw the particular form isopleth in this paper. Themethod gives a solution to the problem that isopleth has the form of branch, circular, oreven separate. The curves approach method of these isopleth is discussed last.
