我们研究了射电响亮类星体样本的扩展射电辐射和线发射之间的关系，该样本既包括核主导类星体，也包括瓣主导类星体。扩展射电辐射和宽线辐射之间存在着很强的相关性。核辐射还与样品中以核为主的类星体的宽线发射相关。波瓣主控类星体的核心辐射的统计行为与核心主控类星体的统计行为有很大不同。扩展射电光度是喷流功率的良好示踪剂，而核心光度只能作为核主类星体的喷流功率示踪剂。
We explore the relationship between the extended radio and line emission for a radio-loud quasar sample including both core-dominated and lobe-dominated quasars. A strong correlation is present between the extended radio and broad-line emission. The core emission is also correlated with the broad-line emission for core-dominated quasars in the sample. The statistical behaviour of the core emission of lobe-dominated quasars is rather different from that of core-dominated quasars. The extended radio luminosity is a good tracer for jet power, while the core luminosity can only be a jet power tracer for core-dominated quasars.
