摘要
本文提出了任意二维区域的描述方法及求取链在环图所表示区域内部部份的算法．从而圆满解决了呈任意区域分布的二维场等值线图的绘制问题。
The modelling method of any region of two dimensions and the algorithm of link's sections within the region that is expressed as loop drawing is put forward and thus the drawing problem of contour map of field that is distributed over any region is solved in this paper.
