摘　　要：不同电性参数的三维地质体在中心回线瞬变电磁观测方式下的数值模拟是认识其电磁响应特征规律并进而开发新解释方法的理论基础。三维地质体的正演是瞬变电磁法研究的一个热点。通过一个具体的模型,讨论了利用 MAFIA 软件进行数值模拟计算的详细方法步骤。据此,可模拟计算任意具有不同电阻率、磁导率和介电常数的三维地质体在不同深度条件下的电磁响应。Numerical simulation for 3 dimensional geologic bodies with different electric property parameters,which is conducted under the way of central loop TEM,is the theoretical foundation for understanding its electromagnetic response characters and developing new interpreting methods.Three dimensional geologic body forward is a highlight of TEM study.A model is used to discuss the procedures in detail for a numerical simulation with MAFIA software.Based on it the electromagnetic response under different depths of the 3 dimensional geologic body with different resistivities,magnetic conductivities and dielectric constants is simulated.
