| 中文摘要: |
| 根据同时实测的相距100km两观测点的电磁场信号,通过比较信号幅值、电磁信号相干性和电磁场相互替代计算视电阻率分析,得出了大地电磁信号中磁信号具有相对均匀性特征的结论,为一些MT勘探工程中需采用电磁分离布极观测提供了试验实例. |
| 英文摘要: |
| Based on electromagnetic signals received simultaneously from two observation sites away from 100km, by comparing signal amplitude and coherence and analyzing apparent resistivity computed with the replacing electromagnetic fields, it is concluded that magnetic signal in magnetotelluric field is homogeneous relatively. This result provides a living test example which adopts apart electromagnetic collection equipment in some MT exploration. |
