| 摘 要： | 本文利用我国部分标准地磁台的观测资料,分析研究了地磁通日、静日和静日午夜年均值与周期远小于一年的短期扰动关系。结果表明,磁暴和地磁周日变化等短期扰动不同程度地影响了通日年均值,地磁年均值的太阳周期变化(长期变化)中含有短周期扰动的贡献。

| Abstract: | In this paper three kinds of annual means of geomagnetic field: the all day means ,the quiet day and the night-time means have been studied by the use of the standard geomagnetic observatory data of china, and the relation between three kinds of annual means and magnetic disturbances with periods shorter than a year have been also studied. It is shown that the effect of magnetic storms and solar diurnal changes cantaminate the all day annual means in different ways.Solar cycle var-iation(secular variation) in the annual mean values of the geomagnetic components contain contribution of disturbances of shorter periods variations. |
