摘　　要：根据Maxwell方程 ,首先引入赫兹矢量 ,导出了层状介质中电偶极子源激发电场的亥姆霍兹方程和边界条件 ,并对其进行求解 ,得到了地表电场表达式 .对于分布有断层的层状介质根据Maxwell方程 ,引入格林张量 ,导出了地表电场的积分表达式 .The Helmholtz's equations and boundary conditions are set up for study on electrical field induced by oscillation dipole source in layered media from the Maxwell's equations and introducing the Hertz electric vector potential.The equations for calculation of electrical field on surface of the layered media are obtained.The integral equations for calculation of electric field on the surface of the layered media with a fault are derived from the Maxwell's equations and introducing the Green's tensor.The equations can be used in numerical simulation of geoelectric field change on earth surface.
