Abstract:The definition and calculation of the apparent resistivity are not the same because of the difference of excitation field sources, working devices and working environments. The calculation methods for apparent resistivity in early-time, late-time and all-time with varying magnetic sources of TEM and different working devices were summarized and reviewed in this paper, and the whole-space apparent resistivity in tunnel and mine TEM in consideration with the turn off time were discussed. Some conclusions and suggestions were proposed based on an analysis of apparent resistivity combined with the development and application of TEM.
