【摘要】 对Fossati,Hartman,Dai and Giridhar等人的研究中所给出的Blazar样本,分别计算从射电到X射线波段、宽波段光谱指数。在此基础上研究了LBLs,HBLs和FSRQs间的宽波段谱指数的相关性质。结果表明,所有的LBLs,HBLs和FSRQs之间αro和αrx存在着较强的相关性质,αro与αox相关性很弱,而αrx=0.75能把LBLs和HBLs区分开,表明它们之间的能谱分布形状是有差异的,这有助于了解的不同种类的blazar内部辐射机制。更多还原

【Abstract】 Using the sample of Blazar presented by Fossati,Hartman,Dai and Giridhar, we calculated the broad-band spectral index from radio to X-ray of each source respectively.We also made a statistical analysis between broad-band spectral indexro?,ox? andrx? for LBLs,HBLs and FSRQs. It is poor correlations between broad-band spectral indexro? andox? between LBLs,HBLs and FSRQs.The main results are as follows:HBLs and LBLs can be separated by the value 0.75,rx? =0.75. It is helpful to understand the radiation mechanism for these different kinds of blazers.更多还原
