| 摘 要： | 地震的孕育是一复杂的物理和力学过程。对于一球型震源体，则会有裂隙由核向外而后液体由外向核的双重扩散过程；与此同时，介质的电磁性质亦相应地发生扩散运动。本从定解问题入手，求得ε、μ、σ的扩散解。根据麦克韦电场理论、求得震源体各向异性介质中麦克斯韦的等价方程与电磁场的基本方程。由此得出震源体介质的似异体性质。对球型导体电磁感应的定解问题，对其频域解分离，得到在外源场作用下震源体中的分量解，即感应场、

| Abstract: | Seismogenesis is a complicated process To a focal sphere it has dual diffusion process that fissure is from heart to out and then liquid from out to heart At the same time, the medium electromagnetic property also generates diffusion This paper has answered the diffusion solution of, and from definite question The anisotropic medium MAXWELL equivalent equation and electromagnetic fundamental equation are answered by MAXWELL electromagnetic theory Thus, the medium quasiconductor nature of focal sphere has been drawn To electromagnetic induction definite question of spherical conductor, allogenic field actuator has drawn the component solution of focal sphere That is induction field, secondary field, magnetization field and primary field The displacement phenomenon of geomagnetic Z component low value time is produced when sum of these field vectors is bigger than geomagnetic Z component max diurnal fluctuation |
