| 英文摘要 | It is one of the classical problems in Earth's electromagnetism that continuation of the observatory data of magnetic field into the conducting region. This paper built the coupling vector equations governing the poloidal, toroidal and potential fields in 3-D inhomogeneous conducting mantle. Considering the limitation on variable scale of inhomogeneities in global mantle from study of the Earth's deep interior, a perturbation theory of gradually lateral variation was presented. It is unnecessary that the 1-D spherical symmetric distribution of electric conductivity as zero-degree approximation. Serving as a example of solvability of the zero-degree approximation, it was demonstrated how the gradually lateral variation of electric conductivity effect on anti-diffusive problem of poloidal field in Earth's mantel. |
