电偶源频率电磁测深中的EX分量

在电偶源频率电磁测深的各场量中，电场ＥＸ分量具有分辨率同，观测信噪比高，不需作近场改正等优点。在有地表电性不均匀引起的静态偏移情况下，可通过转换相位消除静态偏移。因此在资料处理与解释中可不局限于比值电阻率的模式，使频率电磁测深具有更大的灵活性与适应性。

E x COMPONENT IN THE FREQUENCY ELECTROMAGNETIC SOUNDING OF DOUBLE SOURCE

In the various field components of frequency electromagnetic sounding of point double source (including CSAMT),the point field E x component has the advantages such as higher resolution,higher observation signal to noise ratio,need not near field correction and so on.In the case of static offset resulted by the surface electricity inhomogereity,the static offset could be removed by the phase transfer.Therefore,the data processing and interpretation could not be limited to the mode of ratio resistance,resulting that the frequency electromagnetic sounding has larger flexibility and adaptability.
