较详细地介绍了近年来国内外地面瞬变电磁法(TEM)的基本原理、特点、影响因素、测量仪器、数据处理、数据解译(数据的正演和反演)方面的研究状况和所取得的进展,简要介绍了其应用前景,由于具有探测深度大、空间分辨率高等优势,TEM在地质灾害、建筑工程、水文地质工程特别是在深部找矿等方面得以广泛应用。
The basic principles, characteristics, influencing factors, measuring instruments, data processing and interpretation of data (forward and inversion of data) of the domestic and international ground-based transient electromagnetic methods The progress made is briefly introduced. Due to its advantages of large detection depth and high spatial resolution, TEM is widely used in geological disasters, construction engineering, hydrogeological engineering, especially in deep prospecting.
