金咸熙:在频率域中用边界元方法求解地震勘探中的正反演问题,《石油地球物理勘探》,23(2)1988:199～205 在频率域中用边界元方法求解波动方程边值问题,是先对时间变量进行一维傅氏变换,把波动方程化为Helmholtz方程,然后在频率域内用边界元法求解该方程,最后对结果进行反傅氏变换返回到时间域。文中提出的具体计算公式,与文献[1]、[2]提出的计算公式相比较,具有计算精度高和节省计算工作量的优点。
Jin Xianxi: Solving Forward and Inversion Problems in Seismic Prospecting with Boundary Element Method in Frequency Domain, Petroleum Geophysical Prospecting, 23 (2) 1988: 199 ~ 205 Boundary Element Method for Boundary Value Problem of Wave Equation in Frequency Domain , The first one-dimensional Fourier transform is applied to the time variable, the wave equation is transformed into the Helmholtz equation, and then the equation is solved by the boundary element method in the frequency domain. Finally, the result is inverse Fourier transformed and returned to the time domain. Compared with the formulas proposed in [1] and [2], the specific calculation formula proposed in this paper has the advantages of high computational accuracy and saving computational workload.
