摘　　要：为了便于研究地质体中常见层状地质结构的瞬变电磁响应特点,开发了针对板状体的正演计算软件。软件设计采用了面向对象与面向过程的方法,通过动态链接库将两者结合起来。系统界面友好、稳定,可以实现各种板状体的正演计算。二维计算采用有限差分的方法,实现了不同厚度、倾角、电导率的板状体及其组合的计算,计算结果以直观的图形曲线形式展现出来,并可利用其他成图软件进行深加工与研究。A 2D forward system for the layered geological body is developed. With this system, it is convenient to study TEM re- sponse. Progress-oriented and object-oriented methods are both used in the programming of this system, which are connected by the DLL files. The system has comfortable interface and stable performance, and can realize the forward calculation of all kinds of tabular bodies. The finite difference method is adopted in the 2D forward to calculate the tabular bodies with different thicknesses, angles and conductances. The results are shown by the way of curve graph which can be conveniently observed and can also be further studied by other graphic software.
