摘要
时间域电磁测深方法广泛被应用于中深部地质勘探工作中.有关偶极源的电磁响应的正演计算是热点问题.本文从偶极源的电磁响应的理论计算出发,采用对分偶极的方式,将长线源的电磁响应的计算转化为偶极源电磁响应的累加,并根据电磁场的叠加性原理将折线源和环形源的电磁响应的计算转化为多段长线源的电磁响应的累加.这种计算方法对野外施工中的各种不规则的激励源的电磁场的计算非常有效.
It is widely used to the Middle and Deep Geological prospecting for the Time Domain Electromagnetic sounding method.And it is Hotspot on the forward calculating method for the response of Electromagnetic field of Dipole Source.We gave a new way to calculate the response of Electromagnetic field of Long-Line Source by splitting to dipole source in this article.And according to the principal of SUM of electromagnetic field,we can calculate the response of Electromagnetic field of Creased-Line Source and Annular Source by splitting them to Long-Line Source.It is a very effective calculating method for the Non-regular Source of outside field work.
