摘　　要：通过对新疆乌恰地震台附近的地形地貌,水文地质勘察以及介质的电学特性进行了科学的分析论证,认为,该台址条件有利于地电场仪的观测。ZD9A型地电场仪在该台架设与调试后,通过对该仪器的各项仪器指标、观测记录和标定结果的检测分析后,认为,该仪器的各项指标达到了规范的要求,工作正常,并且记录到了正常的地电场日变化形态。此次架台的成功为进一步开展地电场观测工作和为地震预报提供前兆资料奠定了基础。Systematic analysis of the topography, hydrogeology, and the electric properties of the Earth medium around the Wuqia seismological observatory, Xinjiang shows that this station is ideal for the on-site observation of local geoelectric field. Installing and calibrating the ZD9A geoelectric field instrument, analysis is performed on the observational recordings and calibrations results, showing that this instrument has met the requirements of the technique regulations set down by CSB. The instrument has a good performance, having well recorded the daily variation of the local geo-electric field. The installation of this geoelectric station provides the observation of local geo-electric field, as well as the monitoring of potential earthquake precursors, with a sound observational basis.
