在概要分析地电场及地电场观测系统的基础上 ,从地电场测量原理出发 ,着重研究地电场观测系统的各个关键技术环节 (包括 Pb- Pb Cl2 固体不极化电极、 ZD9A地电场仪等 )的工作原理、技术指标、工作方式以及系统连接等 ,并对地电场试验观测台网产出的数据进行了相应的分析。地电场是一个重要的地球物理场 ,已获得的各种观测资料表明 ,基于“ZD9A地电场仪”的地电场观测网 ,真正记录到了地球表面的地电场及其时空变化。地电场观测系统将为进一步开展地球电磁学的综合观测和研究提供技术上的支持。

Based on the analysis of geoelectric field, observational system and the principle of measurement of the geoelectric field, this paper puts the focus on the key techniques of the observation system (including the Pb PbCl 2 solid unpolarized electrode, ZD9A geoelectric field instrument, such as principle of operation, specification, operation mode and system connection and others. The geoelectric field is an important geophysical field. Through analysis of various observed data, we can safely say that the data obtained by the observational network can reflect the earth surface's geoelectric field and its space time variation. This will provide the technical support to the comprehensive observation and research of the geoelectromagnetism.
