摘要
本文基于位段概念,以四子域问题为例,导出了解n个子域问题的非均质边界元总域矩阵方程,给出其相应的计算公式,列举了算例。
Based on the conception of positional segment, the final boundary elementsystem of matrice equations for the nonhomogeneous problem including n subregionswith complex interfaces is derived from the example of four-subregion problem,and the concerned formulations are given. The example of four-subregion problemsolved in this paper is also shown.
