总结出三种求解边界元非对称系数矩阵线性方程组的波前消元法，将建立方程和消元逐行并行交错实现，由此节省了大量的计算机存储量和计算机时，使较大的计算问题容易得到解决．讨论了三种方法求解不同类型的较高阶边界元方程组的效率，并给出了工程连接结构（多子域结构）的实例． Summarizes three kinds of wave front elimination method which solves the linear equations of the matrix of asymmetric coefficient matrix of boundary element, and realizes the establishment of equations and elimination of elements by interleaving line by line and parallel staggering, thus saving a large amount of computer memory and computer, Computational problems are easily solved. The efficiency of the three methods for solving higher-order boundary element equations of different types is discussed, and an example of engineering connection structure (multi-subdomain structure) is given.
