摘要
利用1957—2012年长春地磁台地磁观测数据资料对长春地磁台地磁场的长期变化进行分析研究,系统地总结了长春地磁台地磁场长期变化的规律,揭示了长春地磁台地磁场是以波峰波谷,波浪式的缓慢递增和递减趋势,存在一定的周期性。
Based on the analysis and research of the geomagnetism observing data from 1957 to 2012, long-term variation of Changchun Geomagnetic Observatory has been summarized systematically. The results show that, the geomagnetism in Changchun Geomagnetic Observatory is increasing and declining slowly with a wave mode, and it has some periodicities.
