Abstract This paper uses the maximum entropy method (MEM) to analyze geo-electric data of Changli, Xingji, Xinle, Yangyuan, Feixiang, Dabaishe stations in Hebei province, combined with geomagnetism data, to analyze the spectral features of components of the telluric electric field data. Results show that: the telluric electric field period is mainly 12 h semidiurnal wave components, with 24, 8 h periodic components significantly in Hebei province; during magnetic-storms, the spectrum value is higher than in quiet diurnal variation; telluric electric field of diurnal changes of periodic components come from changing current system of outer space. The results reveal the background spectral components of geo-electric field observation in Hebei province, and provide reference for the application of telluric electric data in earthquake prediction.
