摘要
通过对不同条件下层状介质模型瞬变电磁场数据的波场变换、分析，提高了对瞬变电磁场波场变换物理意义的认识，并总结出若干有价值的规律。指出这种通过数学方法变换出的波场，不仅在形式上满足波动方程，而且在导电介质中也存在“传播”现象，在“传播”过程中，当遇到电性分界面时，也存在“反射”和“透射”。这些结论为在瞬变电磁法中，正确合理地引入地震处理解释方法提供了重要的理论依据。
Through wavefield transformation and transient electromagnetic field data of stratiform medium model under different conditions,the authors have raised the understanding of the physical significance of wavefield transformation of transient electromagnetic field and summed up some valuable regularities.It is pointed out that the wave field obtained from the mathematic trasformation not only satisfies wave equation in form but also exhibits “propagation” phenomenon in conductive media.In the process of “propagation”,the “reflection” and “transmission”phenomena also exist at the electric interface.These conclusions provide important theoretical grounds for reasonable utilization of the seismic processing and interpretation method.
