英文摘要：

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.
