摘　　要：收集了218个blazar天体从射电到X射线的观测数据,计算了宽波段谱指数αr0,αrx和αox,得出HBLs,LBLs,FSRQs的宽波段谱指数αrx,αro和αox都与logvpeak存在明显负相关;LBLs和FSRQs的αrx具有强相关,并且αrx可以作为BLLacs的分类依据;In this thesis, a large sample of 218 blazars was collected, including the observation data from radio to X - ray energy band. The broad band spectral indices αro, arx and αox were calculated. For HBLs, LBLs and FS- RQs, there are negative correlations between the broad band spectral index and synchrotron peak. The correlation between the spectral index and composite spectral index is strong and negative. The αrx vs. αax , are all strongly correlated for all blazars. There is strong correlation of αrx between LBLs and FSRQs. The αrx can be used to classify BL Lacs.
