摘要
回顾了关于大地电流的研究历史和当前大地电流研究所取得的成果,包括大地电流的场源理论、传播途径和频谱特点,重点探讨了大地电流方法在构造勘察方面的应用以及大地电流变异与地震活动的关系等问题,同时提出了对大地电流空间分布及涡旋现象研究的几点新认识。此外,根据大地电流的最新研究成果和相关数据处理新方法,总结出关于大地电流研究的5类新思路。对大地电流研究新成果和新方法的展示,可以促进对大地电流的深入研究,对探索更好的数据处理方法和该学科的发展具有一定的启示意义。
This paper reviewed the history of telluric current research, and the recently achieved results, in- cluding telluric current field source, transmission, spectral characteristics, and focused on the discussion of the ap- plication of telluric current and its relationship with seismic activities and so on. Meanwhile some new cognition of telluric current study was proposed. What＇ s more, based on the latest telluric current research and new data pro- cessing new method, five new ideas on telluric current research were summarized. The demonstration of new results and new methods of telluric current study may promote further research on it and also it has certain enlightenment significance to explore better data processing methods and the development of the subject.
