【摘要】 求解时间域电磁法问题,通常有两种途径。第一,直接求解时间域问题;第二,先解相应的频率域问题,然后变换为时间域问题。本文采用第二种方法,利用Gaver-stohfest逆拉氏变换法将频率测深正演问题转化为对应的瞬变测深正演问题。实际计算表明,该方法是将频率域问题转化为时间域问题的有效方法。更多还原

【Abstract】 Generally, the problem of electromagnetic method in time domain can be solved in two ways. One is to solve the problem directly, the other is to solve the problem in frequency domain first and then transform it into time domain. Gaver-Stehfest inverse Laplace transform method is used to transform the direct problem of E.M. sounding to T. E. M. sounding. It is proved that the method is an effective one transforming the problem of frequency domain to that of time domain.更多还原
