摘要： 本文在文献[1]的基础上,将高阶元引入边界积分方程方法,对导热问题的求解作了详细说明,给出了几个算例。并在精度上与线性元做了比较。

Abstract: The finite element boundary integral equation method to solve heat conduction problems was presented in the paper[1]. A high order element that bases upon the reference[1] is introduced in this paper.The formulas of high order element method are deduced in detail.If the element numbers are same,the results of seueral examples show that the high order element can get much better results than the linear element.
