| 摘 要： | 从文献资料中搜集86个BLAZARS天体在射电22GHz和37GHz波段近10a的观测数据,其中包括38个BLLacs和49个FSRQs.我们对两子类的流量密度进行了平均处理,并得到相应宽带谱指数,分析讨论了谱指数与流量密度、流量密度与红移、谱指数与红移之间的关系,并发现它们之间存在着一定的相关性。

| Abstract: | From many literatures,we have collected 86 Blazars(including 38 BL Lacs and 49 FSRQs about ten years data points of effective observation of Blazars in the radio bands with 22GHz and 37GHz,The average flux densities of two subclasses are calculated,and we also obtained the average abroad spectral index,Some properties are discussed in this paper,Our results shows that the correlation may be existed in the broad band spectral index,redshift and the average flux density |
