摘要
介绍M2 和O1潮引起的地磁太阴日变化L谐波分析方法 ,计算了佘山地磁台的磁偏角、水平和垂直分量L的谐波系数 ,分析了L变化的基本特征 ,季节变化和场源性质 。
The harmonic analysis method of geomagnetic lunar daily variation L caused by M 2 and O 1 tides is introduced; the magnetic declination D and harmonic coefficients for horizontal and vertical intensities H, Z at Sheshan geomagnetic station are calculated; the basic characteristics, seasonal variation and field-source features of L are analyzed and the results are compared with ones from other stations abroad.
