摘要
将高斯积分引入频域格林函数及其导数的数值计算,计算结果与已有文献进行对比,证明该方法在满足足够精度的基础上,使计算过程简化,减少分区,提高计算效率.
We introduce Gaussian quadrature into calculation of frequency-domain Green functions and their partial derivatives. Compared with referenced methods the method proposed simplifies compution, reduces zoning and improves computing efficiency with sufficient accuracy.
