摘要
文章对前兆观测中记录到的方波型异常图像从仪器标定、环境干扰、高压直流干扰、人为干扰、震兆异常等方面进行成因分析,根据不同成因提出干扰方波资料的处理方法和相应的预防措施,对前兆观测数据预处理及异常判定有一定的参考意义。
The square wave abnormal images recorded in precursor observation are analyzed in the aspects of instrument calibration,environmental interference,high voltage direct current disturbance,human disturbance and earthquake precursor anomaly.According to different causes,method of processing interference with square wave data and the corresponding preventive measures are put forward.It has certain reference value for the pretreatment of the precursor observation data and the abnormal decision.
