摘要： 在概要介绍由宝坻、 静海和徐庄子3个测点组成的地电场试验台阵的基础上, 对该试验台阵的地电场观测数据的同步变化、 日变化以及相关性等方面进行了分析研究。 达成如下基本认识: ① 各测点均记录到了典型的地电场日变化, 该变化具有双峰(谷)形态; ② 在空间上具有一定的同步性, 变化幅度与各测点地下介质电性有关, 方位角及其变化可能与各测点观测环境相关联; ③ 2006年7月4日河北文安MS5.1地震前, 静海地电场观测数据中出现了(区别与其他测点的)短周期(小于1小时)变化信息; ④ 短周期(1小时尺度)地电场观测数据互相关分析法, 可以作为评估区域地电场同步变化, 提取非背景变化信息等应用的参考方法之一。

Abstract: This paper briefly introduced the geo-electric field-testing station array, composed of Baodi, Jinghai and Xuzhuangzi earthquake stations, then analyzed its observation data in the aspect of simultaneous changes, daily change, correlation and etc. The result indicates that: ① The typical daily change data of the telluric field are observed at all stations, and it is characteristic of double peaks (valleys). ② The observed data at each station show somehow synchronous changing, the range of the daily change of each station related the underground medium electricity, and the phase change may be related to its environment. ③ Before the Wen′an MS5.1 earthquake in Hebei Province, occurred on July 4, 2006, it was found that the short period signal (less than one hour) had added in the observation data of the Jinghai station, and different from other′s. ④ The method of short period (hours) correlation analysis could be one of the reference approaches in the application, both evaluating the simultaneous change of regional telluric field and identifying the information of non-background changes.
