摘要/Abstract

摘要： 依据国产ZD9A型大地电场仪在天津市宝坻地电台观测到的1998年1月10河北张北6.2级地震过程中记录资料, 通过探讨孕震过程中大地电场时序曲线形态异常、大地电场矢量方位的变化、大地电场振幅｜E｜和极性的变化, 研究了大地电场观测资料的处理方法与地震电信号提取技术。

关键词: 大地电场, 资料处理, 地震电信号, 提取技术

Abstract: According to the seismic recording date obtainned at Baodi station by the ZD9A geoelectric-field instrument made in China, we have studied variation characterictics of the telluric field in the process of M_S6.2 earthquake occurred in Zhangbei area of Hebei Province on Jan. 10, 1998, such as azimuth rotation of the telluric field vector, variation characterictics of 9-Day periodicity, and amplitude and polarity. At the same time, the processing method of telluric field observation data and extrating technique of the SES are studied.

Key words: Telluric field, Observation data, SES, Extracting technique
