摘要
In views of the wrong inversion interpretations resulted from the distortions of both actually tested apparent resistivity and phase curves caused by the static effect in the course of magnetotellurie depth measurement, the maguetotelluric correcting method is presented on the basis of empirical modal decomposition（EMD). The results of the model show that the static effect corrected by EMD can eliminate the distortions caused by apparent resistivity and phase curves.
