【摘要】 本文分析了北京地区Pc3脉动和K指数的关系,研究了Pc3脉动出现频次对不同K指数的分布和日变化,得到了平均周期和K指数之间的经验公式,分析了不同K指数下的Pc3脉动平均周期的日变化。此外,我们把所得的结果和其他人的结果作了比较,并且做了初步的理论解释。更多还原

【Abstract】 The relation between the Pc3 geomagnetic micropulsation and K-index in Beijing is analysed. The distribution and diurnal variation of PC 3 occurrence frequency are studied for different K-indices. An empirical formula between the average period and K-index is obtained. The diurnal variation of PC 3 average period is analyzed. Also, our result has been compared with those of other authors and some preliminary explanations are given.更多还原
