摘要：
In the past four decades, most three-dimensional (3D) modeling and inversion studies on transient electromagnetic (TEM) methods have primarily focused on the time derivative of the magnetic field (abl at), with relatively fewer studies on the magnetic field itself (B -field). Nowadays, with the advancement of the superconducting quantum interference device (SQUID) technique, collecting B -field data in TEM surveys has become more popular. Based on the vector finite-element method, two 3D forward-modeling approaches that are
