摘　　要：在地面核磁共振数值模拟中 ,地下介质中任意一点处磁场的快速计算非常重要。作者针对水平层状介质 ,推导出利用递推方法求得任意一层中电磁波的透射和反射系数的简单方法 ,从而为精确。It is very important to calculate the accurate magnetic fields rapidly in the surface NMR data simulation. An accurate and stable magnetic field computation method, which is based on the recursive relation of the reflection and transmission coefficients in either the same layer or the nearby layers, is developed for an arbitrary point in the layered earth due to the excitation of a large loop source over the layered ground.
