太阳电子注量的~155天周期
Periodicity of ~155 days in solar electron fluence
摘要：
本文首次用三种不同的方法研究了美国宇航局IMP-8航天器在第21太阳周（1976年6月至1986年8月）观测到的高能（E>10 MeV）太阳电子耀斑的发生率，以准确地探测太阳活动的周期性。功率谱分析证实了一个约155天的周期，这与Chowdhury和Ray（2006）的结果一致，即“Rieger周期”在整个周期21中运行，并且它与电子通量的能量无关。
英文摘要：
In this paper we have investigated the occurrence rate of high energetic(E>10 MeV) solar electron flares measured by IMP-8 spacecraft of NASA for solar cycle 21 (June, 1976 to August, 1986) first time by three different methods to detect periodicities accurately. Power-spectrum analysis confirms a periodicity ~155 days which is in consistent with the result of Chowdhury and Ray (2006), that "Rieger periodicity" was operated throughout the cycle 21 and it is independent on the energy of the electron fluxes.
