选择在海洋工程与环境地质等方面有应用前景的海洋瞬变电磁法作为研究对象．研究了在高导海水中探测海底电导率的电磁感应理论，研制了共轴水平磁偶极-偶极装置（HRHR）的瞬变探测系统和解释软件．经东海海域实地试验，取得了良好效果，证实了瞬变电磁探测的有效性和方法优势．目前，它可作为海底地质填图的主要手段．经拓展后可用于海底分层和基底深度的探测．
Select the marine transient electromagnetic method which has application prospect in marine engineering and environmental geology as the research object. The theory of electromagnetic induction for detecting ocean floor conductivity in high conductivity seawater was studied. A transient detection system and interpretation software of coaxial horizontal dipole-dipole device (HRHR) was developed. The field test in the East China Sea has achieved good results, confirming the effectiveness and methodological advantages of transient electromagnetic detection. At present, it can be used as the main means of seabed geological mapping. It can be used for exploration of submarine stratification and basement depth.
