摘要
文本给出了第三类边界条件下矩形长方体、短圆柱非稳态导热的分析解。解的获得是采用分离变量法解导热微分方程式的方法。分析解的结果证明了多维非稳态导热解的乘积法则。
In this paper, The author presented that the analytical solutionof unsteady heat conduction in loug rectangular block and short cylinder withthe boundary condltion of the third kind. The analytical solution is obtained bymeans of solving the differential eguation of heat condution with the method ofseparation of variables. The resules of the analytical solution shoow that the solu-tion of unsteady heat conduction in more than one-dimension has the productrule.
