摘要
梳理并规整邯郸准静电场原始记录图纸和观测数据,对常见干扰因素进行识别和排除;通过震例总结,研究电场观测数据异常变化特征,确定短期预报指标,探讨异常信息与地震的关系。结果表明:异常出现后,大多在3个月内发生地震,震级和异常信息持续时间成正比,震级越大,异常持续时间越长。
Based on comprehensively hackling and structuring original record of drawing and observationdata on Handan quasi-electrostatic field,recognizing and eliminating the common interferencefactor,summarizing the earthquake cases,researching abnormally changed characteristics,anddetermining the short-term prediction indexes,the relationship between anomaly information andearthquake is preliminarily studied.The results showed that after the anomaly appeared,mostearthquakes occurred in three months,and the earthquake magnitude is directly proportionalto duration of abnormal information.The greater the earthquake magnitude is,the longer theduration.
