| Abstract: | By analyzing the features and law of data storage of geoelectric field,an software is developed with Mablab.The software can make spectrum analysis of geoelectric data and output results in text fomat The software also has functions to extract amplitudes of daily wave and semidiurnal wave according to your selected time,which will be helpful for researchers to look over the variation of geoelectric spectrum and its variation with time and study the earthquake precursors.In addition,with some modifications,this software can be taken as a template to process the data of other instruments with another analysis methods. |
