【摘要】通过数字与模拟观测对比分析,说明数模观测的一致性,结合近几年河北省及邻区中强地震,进行震例分析和研究。应用结果表明:数字与模拟观测变化一致性较好;震前数字电磁扰动出现异常变化,异常形态为:原始采集波形出现扰动变化、日均值或日总量出现高值突跳、日总量背景值上升等。更多还原

【Abstract】 In this text,the development background of CNEM08-I digital electric disturbed equipment, and its observation and analytic system are introduced.The results of digital observation and analogous observation system are accordance by compared those waveforms.Analyzing and researching the earthquakes in and around Hebei Province,application manifests that digital and analogous observation is accordance.Electromagnetic disturbance has abnormal changes before earthquakes.The abnormal shapes present that digital observed original collecting wave is disturbed,the day mean value or total value flips,or the background of day total value is upward.更多还原
