摘　　要：探讨了开发二维热传导方程可视化计算软件的功能及在该软件研制过程中所解决的若干问题.该软件可对一类二维抛物型偏微分方程进行差分求解,再把所得的海量数字形式的数据转换为动态变化的图形(类似于气象预报中的云图),即根据输入的边界条件与初始条件,直接输出可视化的计算结果.The function of a software developed by visial C++ for visualization computing with two dimensional heat equation and some solved problems in developing the software were discussed. The results showed that the software can change lots of numerical data abtained from the two dimensional parabolic equation to the dynamic images such as cloud image in weather forecast. Thus, according to the initial conditions and boundary conditions the software can directly output the visualization computing results.
