摘要
推导了EDA型层状各向异性介质大地电磁测深正演计算公式 ,对多种模型从不同的频率、测量方向计算了地表视电阻率曲线。结果表明 ,一般的各向异性介质的地表视电阻率值不仅与测量频率有关 ,而且与测量方向相对电性主轴的交角有关。
The forward calculation equations are derived for MT in the EDA type anisotropy media, and numerical simulation of apparent resistivity consists of several models with different frequency and observations is presented. The results show that for EDA type anisotropy media the apparent resistivity varies with frequency and observational directions as well.
