将冯康和余德浩提出的自然边界归化方法用于研究一类半线性椭圆方程外区域问题，提出一种自然边界元与有限元的耦合算法。
The finite element method is combined with the natural boundary element method to study the weak solvability and Galerkin approximations of a class of semilinear exterior boundary value problems .

我国学者冯康、余德浩等首创自然边界元法，并已成功地研究了调和方程及双调和方程边值问题的自然边界归化方法。
FENG Kang , YU De-hao and some other scholars of our country are the first ones to create the natural boundary element method ( NBEM ), and they have successfully studied the natural boundary reduction method for the boundary value problems of harmonic equation and biharmonic equation .
