摘要
对山西省地震局夏县中心地震台D JY—2000A型地震电磁波脉冲观测系统的观测资料进行了分析,认为,要对已获得的电磁前兆信息作出真实评价,除对观测系统进行定期标定外,仪器稳定性是决定其映震能力的一个重要因素。实践表明,该观测项目出现的异常与一些中强地震有明显的对应关系。
Data from the observation system of DJY-2000A seismic electromagnetic impulse of Xiaxian seismological station is analyzed.It is pointed out that for a true evaluation for captured electromagnetic precursor information,the stability of apparatus is an important factor for its earthquake reflecting capability,besides periodic calibrating the observation system.The practice shows that there are distinct corresponding relations between the anomaly of this observation and some medium-strong earthquakes.
