| 摘 要： | 本文提出了一种求解本征值问题的改进边界元技术,它是将Laplace方程对应的基本解用于Helmholtz方程,从而使形成的边界元方程不隐含本征量,这样大大降低了对计算机内存的要求,并提高了求解速度。

| Abstract: | A modified boundary element technique is proposed for the investigation of eigenvalue problems. In the approach, the foundamental solution corresponding to Laplace's equation is employed for Helmholtz's equation, thus the matrices in the formed boundary equation implicitly contain no eigen parameter. Therefore, this method only requires a small computer memory, and decreases the computation time. |
