| 摘 要： | 给出了多种策略相结合绘制等值线的方法。先用Delaunay三角化的Watson算法，将生成网格和产生新结点一体化，形成三角网格，节省了计算时间。然后用Kriging算法，通过设计不同的权值，实现了对离散点的插值。最后用三次抛物线的滑动平均法将街值点连接成光滑的曲线，并对曲线后表示的数值进行了注记。该方法具有运算速度快，插值精度高，图像美观的优点。

| Abstract: | A multi-strategy method of drawing isoline is given.Watson algorithm is firstly given to form triangular grid and during which the formation of grid is integrated with the formation of new node,thus runtime is saved.Then the interpolation betwwen discrete node is realized through designing different weight value using Kriging algorithm.Finally all the equivalence nodes are linked to a slippery curve by cube parabolic sleek evenness method and the curve is plotted.Computing speed has been increased by the multi-strategy method. |
