在摄动法的框架下分析了非定常一维热传导问题。结果表明，可以建立简单的中心、表面和平均温度的一阶模型。给出了板、无限长圆柱体和球体的阶跃响应。
Unsteady one-dimensional heat conduction problem is analysed within the framework of a perturbation method. It is shown that simple first order models for the centre, the surface and the average temperature can be developed. The step responses are given for the slab, the infinite cylinder and the sphere.
