| 摘 要： | 本文对视超光速源样本的有关数据进行统计分析，检验活动星系核统一模式。给出各类视超光速源的Ｒ（核光度与扩展区光度之比）分布和喷流与视线的平均夹角 。分析源样本的Ｒ、洛伦兹因子ｒ、喷流的投影尺度ｄ和线性尺度ｌ间的关系，发现Ｒ和ｄ之间存在反相关、ｒ和ｌ之间存在相关的特性，这些结果有利于说明活动星系核统一模式的取向效应。

| Abstract: | This paper makes statistic analyses with a sample of superluminal sources to test unified schemes in Active Galactic Nuclei(AGNs).The distributions of the ratio R of core emission to extended emission and average viewing angle of various types of AGNs are presented.By analysing R,Lorentz factors, projected angular sizes and deprojected linear scales of the sample,we find an anticorrelation between R and projected angular sizes and a correlation between Lorentz factors and deprojected linear scales. These results are in support of the orientation effect of unified schemes. |
