一般情况下，边界元法所建立的线性方程组系数矩阵为一满置矩阵。

In general situation, the coefficient matrix of linear equations deduced by the Boundary Element Method (BEM) is a compact one.

但由于边界元法得到的求解代数方程组的系数矩阵是满阵，对其解题规模有很大的制约作用。

But the scale of the problem that can be solved by BEM is greatly limited, because the matrix of the system equations generated by BEM is fully populated and unsymmetrical.
