摘　　要：从分析各种网格法的缺点入手,依次介绍了从数据网格可视化,等值面图到等值线图的详细过程.这种等值线绘制的方法综合利用了AutoCAD、Photoshop、Fortran等几种工具,通过逆向思维和转换处理,把一个复杂的等值线绘制问题分解成了几个简单的问题.该法对工程实际而言更简单、方便、易掌握,且从实用的意义上来说,是值得推广并继续深入研究的.The shortcomings of different grid division methods are analyzed; and the specific process which is from the grid data visualization, following the surface map of isoline, to the isoline map, is described sequentially. This kind of new method utilizes such several kinds of tools as AutoCAD, PHOTOSHOP, FORTRAN, etc. , synthetically; through reverse thought, and divides the complicated question of drawing isoline into several simple problems. This method is simpler, more convenient in real project than another. Most of all, it easy to master, and has certain value in popularizing and further study, in a practical sense.
