电磁频率测深法已取得了可喜成果,但现有仪器的探测深度最浅一般40米左右。高频端所测曲线因元器件的频率特性和干扰因素及测量装置的影响,其精度较差,因此对地表浅部地质构造的探测,尤其对解决水文地质和工程地质问题无能为力。更重要的是,当对频磁曲线作定性定量解释时,由于缺少首支曲线,在国产量板上不能求出定量
Electromagnetic frequency sounding method has made gratifying achievements, but the shallowest depth of the existing instruments is generally about 40 meters. The high-frequency end of the measured curve due to the frequency characteristics of components and interference factors and measuring devices, the accuracy of the poor, so the shallow surface of the geological structure of the detection, especially to solve hydrogeological and engineering geological problems can not do anything. More importantly, when the qualitative and quantitative interpretation of the frequency magnetic curve, due to the lack of the first curve, can not be found in the domestic volumetric plate quantitative
