【摘要】 本文对1986年1月北京地区Pc3地磁脉动进行了偏振特征的分析,分别找出了北京地区Pc3地磁脉动在磁静日期间和磁扰日期间偏振旋转方向随地方时变化的规律,以及偏振主轴方向随地方时变化的规律。 根据Pc3地磁脉动的偏振分析,可以了解北京地区Pc3脉动的激发机制,为进一步磁层诊断提供科学依据。更多还原

【Abstract】 In this paper, the polarized characteristics of Pc3 pulsation data recorded in Beijing in January 1986 are analyzed . The variation of the sense of polarization for Pc3 and the change of orientation of its main axis with local time have been found in both geomagnetic quiet and disturbed days.According to the polarization analysis of Pc3 pulsations in Beijing, the mechanism of their exitation at low latitude can be discussed and the evidence of magnetospheric diagnosis is provided.更多还原
