摘要
计算的几种模型表明，用改进的三维有限差分法程序计算的异常体中心点上的水平磁场实部可达 1.53，这就意味着水平场转换函数 Cu也可达 1.53，与单台垂直磁场的转换函数有相同量级的大小。
The modeling calculations indicated that the real part of horizontal magnetic component at the center point is taken to 1.53 by the improved 3D finite difference calculation. This result implies that the horizontal magnetism field transfers function Cu is also taken to be 1.53. In other words, the Cu possesses same magnitude of vertical magnetism field transfer function observed from the single station.
