In this paper, we use the distributions of two-component radio emissions to investigate the consequences of relativistic beaming on the unified scheme of blazar populations and radio galaxies. Our results show remarkable continuity in the distributions of source luminosities (radio core and extended luminosities, \(L_{C}\) and \(L_{E}\) respectively as well as \(\gamma \)-ray luminosity \(L_{\gamma }\)) from radio galaxies at low luminosities to FSRQs at high luminosities through BL subclasses as expected in the blazar unification scheme in a sense suggesting that the sequence of BL Lacs, FSRQs and radio galaxies represents progressively misaligned populations of AGNs. Distribution of radio core-dominance is consistent with average projection angles of 13.5^∘, 14.8^∘, 16.8^∘, 20.4^∘ and 28.2^∘ for ISPs, LSPs, FSRQs, HSPs, and radio galaxies, respectively. Linear regression analyses of our data yield significant anti-correlation (\(r > 0.60\)) between core-dominance parameter (\(C\)) and \(L_{E}\) in each individual subsample: the correlation is significant only when individual subsamples are considered. There is a systematic sequence of the distribution of the different subclasses on the \(C - L_{E}\) plane. Nevertheless, little or no correlation between \(C\) and \(L_{C}\) or between \(C\) and \(L_{\gamma }\) (\(r < 0.50\)) was observed. There is a clear dichotomy between high synchrotron-peaking BL Lacs and other BL Lac subclasses. The results are consistent with a unified view for blazars and can be understood in terms of relativistic beaming persisting at largest scales.

在本文中，我们使用两分量无线电发射的分布来研究相对论射束对blazar种群和无线电星系统一方案的影响。我们的结果表明，源光度（无线电核心和扩展光度，分别为\（L_ {C} \）和\（L_ {E} \）以及\（\ gamma \）-射线发光度\（ L _ {\ gamma} \））从blazar统一方案中预期的那样通过BL子类从低亮度的射电星系到高亮度的FSRQ，从某种意义上说，这表明BL Lacs，FSRQ和射电星系的序列代表AGN的群体逐渐错位。无线电芯显性的分布是13.5平均投影角一致^∘，14.8 ^∘，16.8 ^∘，20.4 ^∘和28.2 ^∘，分别为ISP，LSP时，FSRQs，热休克蛋白，和无线电星系。我们数据的线性回归分析在核心支配参数（\（C \））和\（L_ {E} \）之间产生了显着的反相关（\（r> 0.60 \））在每个单独的子样本中：仅当考虑单个子样本时，相关性才有意义。\（C-L_ {E} \）平面上有不同子类的分布的系统序列。然而，观察到\（C \）与\（L_ {C} \）之间或\（C \）与\（L _ {\ gamma} \）之间几乎没有相关性（\（r <0.50 \））。在讲高同步加速器的BL Lacs与其他BL Lac子类之间存在明显的二分法。结果与统一的观点一致，并且可以从相对论光束最大规模持续的角度来理解。
