| 摘 要： | 从文献中收集了11个Blazar天体在22GHz和37GHz射电辐射流量的观测数据,获得了这些天体从1980-2005年射电辐射流量的变化曲线。用Jurkevich方法分析研究了它们射电辐射流量的变化周期。结果表明:11个天体在22GHz和37GHz波段都表现出周期性变化的特征,变化周期从1.4年至10.4年不等,并且天体在22GHz和37GHz的变化特征基本相同。对得到的周期分析结果作了简要讨论。

| Abstract: | In this paper,we have collected the radio flux data of 11 Blazar objects in 22GHz and 37GHz from the literatures,and constructed its long-term light curve of radio flux from 1980 to 2005.Using the Jurkevich method,we have been studying the radio flux period of 11 Blazar objects.Our results show: It is the general characteristic for 11 Blazar objects for the periodic variation in 22GHz and 37GHz radio flux,and the range of the periodic change from 1.4 to 10.4 year.The variational characteristic is basically ... |
