摘　　要：针对离散点的情况,通过总结各种等值线的生成方法,提出了一种新的绘制等值线的方法———正方形网格法。该法避免了烦琐的离散点网格化和等值线的游动,编制程序简单,运算量小,输入数据少,绘制图形精度高、速度快、效果好,具有通用性。Aiming at dispersion point, this paper summarizes various methods of forming contour line, then puts forward a kind of method which called square mesh. This method does not need dispersion point meshing and contour searching. Program develpment for the method quantity is simple, calculation quantity is small, importation input is little, accuracy is high, the speed is quick, and the method has veratility.
