摘　　要：文章在分析了国内外地电场观测与研究的基本概况、发展历史、目前面临的主要问题等基础上,研究完成了一种应用于地震监测研究的新型网络化地电场观测技术系统.首先对地电场观测方法进行了模型研究和论述,然后对最新研究完成的地电场观测技术系统的主要研究进展进行了详细分析,包括固体不极化电极、新型网络化地电场观测仪器的基本原理与技术实现,典型已知源非工频干扰的处理方法和抑制效果等,最后对新型网络化地电场仪器数据产出的客观性、真实性、可靠性进行了分析讨论.文章阐述的基于"ZD9A-2B地电场仪"的新型网络化地电场观测技术系统,秉承了我国"多方向、多极距"地电场高精度同步观测的各项技术要求,同时在电极极化电位问题、电磁环境干扰问题、低功耗和便携式应用、以及在高寒地区的环境适应能力等方面,取得了重要进展,并在"中国地震背景场探测工程"项目中得到应用.研究结果表明,这种新型网络化地电场观测技术系统,在应用过程中,获得了能够客观、真实反映地电场物理量变化特性的观测数据,具备了在特殊环境下开展地电场无人值守长期定点连续观测的能力,对我国地电场观测和研究工作的进一步发展具有一定的促进和保障作用.In this paper,based on the analysis of the general situation,development history,the current main problems,et al.,of the domestic and foreign geo-electric field observation and research, a new type networked geo-electric field observation technology system for earthquake monitoring and research is completed. Firstly,research and discussion the mode of the geoelectric field observation method. And then,detailed analysis the main research progress for the newly research completed of the geoelectric field observation system,including the basic principle and technology realization of the solid non-polarized electrodes and the new type networked geo-electric field observation instrument,and the processing method and the suppression effect of the non-power frequency interference of some typical source, et al. Finally,analysis and discussion the objectivity,authenticity and reliability about the observation data of this new type networked geo-electric field instrument. In the paper,it was elaborated that the new type networked geo-electric field observation system based on＂ZD9A-2B Geo-electric Field Meter ＂, was adhering to the technical requirements for the high precision synchronous observation of the geo-electric field,with the method of ＂multi direction multi electrode distance＂which had been developed in China,and had made important progress in solving several problem, such as polarization potential, electromagnetic environment interference,low power consumption and portable application,the adaptability of environment in alpine cold regions,et al.,and it is applied in the project of ＂Chinese seismic background detection Engineering ＂.According to the research results,this new type networked geoelectric field observation system,have obtained the objective and true observation data in application which reflected the change of geo-electric physical quantity,and have the long-term fixed-point continuous observation ability under the complex and special circumstances for unattended observation.
