摘　　要：将海水看作线形、均匀、各向同性的半无限大导体空间,利用汉克尔变换及开尔文函数近似展开式求得极低频时谐点电极产生的电场强度解析式,然后利用矢量叠加方法可以推导出极低频时谐环形电流源产生的电场强度解析式,进而可以计算海水中任意场点的电场值。By applying the Hankel transform and the polynomial approximate expression of Kelvin functions,the analytical expressions of the electric fields are presented for a extremely low frequency(ELF),time-harmonic,point-electrode in the deep sea.And then by applying the sum of the vector,the analytical expressions of the electric fields are presented for the circle electric current.Finally,the electric fields on any points in sea water can be worked out.
