摘　　要：精度的高低是考量地电场观测的一项重要指标,通过对阳原地震台近10年的观测精度进行分析(主要针对背景场项目改造后的观测数据),并对目前使用的JH-020型不极化电极观测及深埋处理进行研究,得出使用JH-020型不极化电极观测及电极深埋处理是有效提高观测精度的可行方法。同时,也为全省乃至全国台站提供地电场观测的有益借鉴。The accuracy is an important index to evaluate the observation of the geoelectric field.By analyzing the observation accuracy of Yangyuan seismic station in recent 10 years(mainly for the observation data after the reconstruction of background field project),and studying the JH-020 non-polarized electrode observation and deep burial treatment,it is concluded that the use of JH-020 non-polarized electrode observation and deep buried treatment is an effective way to improve the accuracy of observation.At the same time,it also provides a useful reference for the observation of geoelectric field in the whole province and even the whole country.
