| 摘 要： | 基于一维不稳态导热分析解，提出一个在第三类边界条件下的二维和三维不稳态加热时间的计算方法。其中，在求解超越方程μ／Bi=ctgu和J0（β）M（β）=β/βi的根时，应用牛顿插值法求解甚为方便。

| Abstract: | Based on the one dimensional analytical solution, a new calculation of two and three dimensional unsteady heating time is provided under a third boundary conditions. In solving of the root values with,μ/Bi = ctgμfor a large slab and J0 （β）/J1 （β） =β/βi for a cylindel; the Newton insert method may be more applicable for the solution. |
