英文摘要	Based on the relationship between the transient electromagnetic diffusion equation and wave equation, the data of time domain field is transformed into a pseudo wave-field. We then propose that the transformed wave can be extended from surface into ground by the Kirchhoff integral method. During the numerical calculation of surface extension, in order to improve the computing efficiency, three-dimensional boundary element method has been used. The equations of surface extension have been established after separating the boundary integral into lots of Triangle unit integral. The wave-field corresponding to underground point has been reached by the wave-field value of surface point. The continuation imaging at the curved surface has been realized at last. The theoretical model and the real application both show that the method can strengthen the capacity of the transient electromagnetic method to identify the underground electrical interface, and make the transient electromagnetic method in 3-D fine exploration possible.
