摘要
利用我国低纬地区琼中、广州和泉州３个地磁台１９８２—１９８９年的地磁静日实测值，分析了Ｈ、Ｚ和Ｙ三个地磁分量的谐波特征。结果表明，①Ｈ、Ｚ两分量的谐波振幅一般在春秋季最大，冬季最小，Ｙ分量的谐波振幅在夏季最大，冬季最小，它们的变化形态基本上与太阳黑子数的变化形态同步；②三分量的相位都受到太阳活动和季节的影响。
In this paper,the geomagnetic quiet-day's variations H.Z.Y of three geomagnetic observatories Qiongzhong,Guangzhou,Quanzhou at low latitudes in China 1982-1989 were analysed,the harmonic characteristics of them were,the amplitudes of horizontal and vertical components are generally maximum during equinox and minmum during winter,the amplitude of eastern component Y is maximum during summer and minmum during winter.Their variation shapes are consistent with sunspot variation shapes.The phases of three components are influenced by different season and solar activity.
