摘要：

To enhance the vertical resolution of direct current resistivity method, this study introduces differential and integrating arrays and explains the basic principle and expression of apparent resistivity. Forward and inversion modelling in layered media was conducted to demonstrate the vertical resolution of these two arrays through several examples. The results indicate that the differential array has improved sensitivity and vertical resolution compared to other arrays for layered media structures. However, the integral and dipole-dipole arrays have the same resolution to the underground structures, which is inferior to the differential array.
