摘　　要：本文分析了地下的垂直电或磁偶极子在地面上产生的电磁场。本文采用的近似适用范围是 k_0R_0<<1,但 k_1R_0可与1比拟。此地 R_0是观察点与偶极子之间的距离,k_0和 k_1是电波在空气与土壤中的传播波数。The electric and magnetic field components produced by the buried vertical elec- tric or magnetic dipole are derived and presented here for the quasi-near range.The distance R_0 between the observed point and the dipole is assumed as k_0R_0<<1,but k_1R_0 is comparable to 1,where k_0 and k_1 are the propagation wave number in the air and in the earth.
