摘要：
Complex terrain causes great MT noise.This paper puts forward a FEM model method using adaptive topography and quadratic elements based on studies by previous researchers.This method can model all kinds of complicated terrain and geoelectric bodies preferably.The numeric modeling,calculation of the auxiliary field and definition of resistivity are deduced by electromagnetic equations.Lastly,several examples are presented,which show the method is rapid,effective and has highly accurate.
