| 摘 要： | 本文用热源法对简单热传导问题进行了解析解的计算，并应用PDE工具箱求解热传导偏微分方程得到数值解。通过两种温度场的计算结果求出相应的位移场结果，比较可知MATLAB中PDE工具箱对难以用解析法求解的热传导问题有一定的指导作用。

| Abstract: | On the basis of computationing the simple equation of heat conduction with thermal resource method,the analytic solution was gotten,and resolving the partial differential equation of heat conduction with PDE tool box,the numerical solution was gotten.With the two results,the corresponding displacement field solution was gotten,In comparison the PDE tool box was found to have guide meaning in resolving heat conductivity problem which is hard to resolve with analytic method. |
