Abstract: 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.
