The double current supply, inline and combined pole-dipole/dipole-pole array for time domain induced polarization method is an unsymmetrical arrangement sounding technology composed of forward pole-dipole and reverse dipole-pole array. This paper shows the sounding principle with graphical representation. For collecting resistivity and chargeability raw data distribution features in the pseudosection with forward pole-dipole and reverse dipole-pole array, it is similar to MT in that MT raw data obtain "static state effect", and resistivity and chargeability raw data also obtain "partial topography” and "electromagnetism noise" effect and assumes "false belt anomaly" features. Forward pole-dipole and reverse dipole-pole array obtains resistivity and chargeability data and can respectively process two-dimension inversion, but only the combined pole-dipole/dipole-pole array can get the best geological effect, indicating that the strongpoint of the electrodes configuration array is that it can obtain massive collection data, strong induced polarization signal, larger penetration depth and highly surveying accuracy.
