在可控源音频大地电磁法野外作业中，源和勘探区间的距离可达几公里，为了了解源和勘探区间的异常体对勘探区内异常响应的影响，我们用三维压缩积分方程法做了数值模拟研究。

The experiment shows that CSELF is potentially valuable for earthquake research and prediction. It is also found that the recorded electric and magnetic component amplitude of CSELF signal varies depending on the distance and azimuth of the observatories relative to the transmitter. These amplitudes decline with increasing distance between observatory and transmitter faster within some space extent than those outside the extent. It may be easier for magnetic components to have higher ratio of signal to noise than for electric component.

试验还发现，各地震台站和流动测点观测的CSELF信号的强度，与台站或者测量的电、磁场分量相对于发射源的距离、方位有明显的关系；发现在离开发射源的相对近区，场强随距离的衰减，比在相对远区更快；发现接收磁场信号比电场信号较易获得更高信噪比的数据。
