摘　　要：参考国外有关文献介绍的方法,通过两个不同方式的磁场测量求取了水平层状介质表面上垂直磁偶极源电磁场及其全频域视电阻率的表达式,简介了视电阻率的数值计算方法,并且用自编程序计算了几种地电断面的视电阻率曲线,以此说明所介绍方法的有效性。This paper derived the equations of vertical magnetic dipole source electromagnetic field and its apparentresistivity in full frequency band for the magnetic field measurements of two different configurations, and brieflyintroduced the numerical calculation method of apparent resistivity. The effectiveness of the method was verifiedwith apparent resistivity curves calculated from several geoelectric cross sections with program coded by the au-thor.
