寻找地磁偏角的中长期变化规律,是识别异常、验证观测资料可靠性、仪器工作是否正常的重要依据。地磁场的长期变化是一个区域性现象,要摸索以磁报震的方法,需要寻找出本地区地磁偏角的年变特征。
Looking for the long-term variation law of declination of earth’s magnetic is an important basis for identifying anomaly, verifying the reliability of observed data and whether the instrument is working normally. The long-term change of the geomagnetic field is a regional phenomenon. To explore the method of using the maglev method, we need to find out the annual variation characteristics of the declination of the earth’s magnetic field in this area.
