摘　　要：计算每个Blzars天体从射电到X射线波段全波段光谱指数,采用KS检验方法对比了耀变体子类LBLs、HBLs和FSRQs间的宽波段谱指数的相关性质,分析结果表明三类天体的α_(ox)相关性很弱,所有的LBLs和FSRQs之间α_(rx)存在着较强的相关性质,而LBLs和HBLs的αrx相关性很弱,而α_(rx)=0.75可以作为LBLs和HBLs分类依据。The broad - band spectral index from radio to X - ray of each source is calculated respectively. A statistical analysis between broad - band spectral index αrx , αro , αox, for LBLs, H BLs and FSRQs is also made. It is poor correlations between broad - band spectral index roand αox between LBLs, HBLs and FSRQs. The main results are as follows ： HBLs and LBLs can be separated by the value 0. 75,αrx = 0. 75. It is helpful to understand the radiation mechanism for these different kinds of blazers. HBLs and LBLs can be separated by the value 0.75 αrx = 0.75. It is helpful to understand the radiation mechanism for these different kinds of blaz- ers.
