摘要
根据北京明陵地磁台2010年观测数据,采用磁静日数据,选用其特征值——日变幅度和相位,对太阳静日变化特征进行了初步分析,并用调和分析方法将其分解为3个周期的谐波分量。对地磁数据的分析处理具有一定的参考价值。
According to the geomagnetic quiet daily data collected from Beijing Ming Tobmb geomagnetic observatory in 2010, we choose the daily variation amplitude and phase to primarily analyze the characteristic of geomagnetic quiet daily variation, and decompose the solar quiet daily variant into three periodic harmonic functions by harmonic analysis methods. This paper is useful for geomagnetic data analysis.
