研究了分层(五层)地球模型的理论大地电磁 (MT) 探测,该模型由两个电导率随深度线性变化的过渡层和三个电导率恒定的均匀层组成。切向电场和磁场以及表面阻抗的解析表达式是根据艾里函数导出的。详细研究了两个过渡层和它们之间的夹层的厚度对 MT 响应(视电阻率和阻抗相位)的影响。
Theoretical magnetotelluric (MT) soundings are investigated for a stratified (five-layered) Earth model consisting of two transitional layers with conductivity varying linearly with depth, and three homogeneous layers with constant conductivity. The analytical expressions for the tangential electric and magnetic fields as well as the surface impedance are derived in terms of Airy functions. The effect of the thicknesses of the two transitional layers and the interlayer between them on the MT responses (apparent resistivity and impedance phase) is examined in detail.
