摘要
根据北京地磁台1987~2012年已正式出版的《地磁观测报告》资料,对北京地磁台地磁场的长期变化进行初步分析研究。系统地总结了北京地磁台地磁场长期变化的基本规律,这对进一步认识了解北京地磁台地磁场各要素的变化规律与特征,以及应用北京地磁台的资料有一定的意义。
According to the observation data at Beijing geomagnetic observatory from 1987 to 2012, we summarize and analyze the laws of the geomagnetic secular variation in Beijing geomagnetic observatory.This work is significant for further understanding the variation laws and features of every component of geomagnetic field at Beijing geomagnetic observatory, and provides useful primary material for earthquake research.
