中文摘要：

瞬变电磁法已广泛应用于固体矿产勘探、水文地质调查等领域,并有许多实例文章见刊.然而,这些实例背后蕴含的地电模型却研究很少.本文将应用于瞬变电磁法勘探的地电模型分为四类：矿床学模型、水文地质模型、地质构造模型和人文模型,并分析了部分模型的相关实例.最后,我们认为特定地电模型分析和地下流体动态监测为瞬变电磁法的两个重点发展方向.

英文摘要：

Transient electromagnetic method（ TEM） has been applied widely in many fields,e. g. prospecting solid mineral resource,hydrogeologic survey and so on. Furthermore,there are numerous field cases published in mainstream journals about geophysical prospecting. However, the geoelectric models underlying these cases barely are researched. In this paper,we firstly classified the geoelectric models employed in transient electromagnetic prospecting as four types： mineral deposits model,hydrogeological model,tectonic model and cultural model. Then,we analyzed some typical cases in regard to these models. Finally,we hold that there are two prospective aspects： analyzing the characteristics about these models by three dimensional forward solvers and monitoring subsurface fluids by TEM dynamically.
