摘要
通过对张北６．２级地震前辽中台接收的电磁信号研究分析，总结出这次距辽中台 ６００ｋｍ、６级地震前的电磁前兆信号，具有弱～强～弱～平静后发震的总变化过程．异常信息 具有异常时间长、信号强、异常范围大的特征．
By analyzing the receiving electromagnetic signals in Liaozhong seismic station prior to the Zhangbei Ms 6.2 earthquake, the variation process of electromagnetic for warning signals of the Zhangbei Ms6.2 earthquake 600km far away from Liaozhong is summarized of week-strong-week, after a quiet period. the earthquake happened. The abnormal signal has the features of long-time, strong, and large-extension.
