摘要 以Sambruna选取的52个BL Lac天体为测试样本,对HBLs和LBLs的αx,fx/fr,αox和复合谱指数间的关系作了初步分析,结果表明两个子类有不同的特性,支持其具有不同X射线辐射机制的假说. We investigated αx, fx/fr, αox and the composite spectral indices of the sample of 52 BL Lacertae objects given by Sambruna. We found that HBLs and LBLs have the different X- ray emission mechanism.
