摘要
On the basis of a study and analysis of three sets of dominant transient electromagnetic software abroad (Maxwell, EM vision and Emigma), the authors designed tabular or prismatic bodies with homogeneous half-space, layered earth and homogeneous half-space and compares the difference between them. 1D inversion was carried out with homogeneous half-space and layered earth too. The forward and inversion results have led the authors to reach the conclusion that in some circumstances these sets of software can yield the same results, but there still exist some differences under different conditions.
