摘要
本文用正则摄动法将一类非线性热传导方程分离为若干个线性方程,再逐个推导出其有限元计算格式。这种方法与一般有限元方法相比,可显著地节省计算时间,算例表明计算效果良好。
In this paper the regular pertubation technique combined with FEM is used to solve a kind of nonlinear heat conduction problem. An example and all of the formulae are given. By means of this method the computational time can be notably saved.
