| Abstract: | The general situation of geoelectric field observation in Dulan region is introduced.The observation date recorded from 2014 to 2017 are selected and analyzed.The results indicate that observation data in DuLan station can reflect the actual change of the observation site.The interference sources can be quickly judged by the different characteristics and amplitudes,and corresponding measures are also provided,which provide basic work for earthquake prediction. |
