中文摘要：

从多篇文献中收集了402个活动星系核（AGN）的有关数据，研究了AGNs样本的核主导系数与核心光度及延展元光度的关系．结果显示：核主导系数与核心光度之间存在强线性相关，相关系数r=0．692，置信度P〈10^-4，而核主导系数与延展元光度之间不存在相关．所得结果支持AGN的相对论喷流模型．

英文摘要：

402 Active Galactic Nuclei（AGN） sources were collected from some academic articles. Using the linear regression analysis, the correlations between Core-dominated parameter （R） and Core luminosity （LC）, and Core-dominated parameter and extended luminosity （LE） were investigated. Results show that there was a good correlation between R and LC, with a correlation coefficient of r = 0.692, and chance probability P 〈 10^-4. There was no correlation between R and LE. These results support the relativistic beaming model.
