【摘要】 从相关文献中我们收集了141个具有核光度和扩展光度的射电噪类星体,并研究了核主导参数R与核光度LC、扩展光度LE以及红衣z之间的关系。结果表明R与LC之间存在强的正相关,R与LE之间存在强的负相关,而R与z之间有弱的甚至没有相关性,这与樊军辉和张江水得到的结果是一致的。他们之间的这些相关性能被聚束效应解释。更多还原

【Abstract】 In this paper,we have chosen a sample of 141 quasars which have both core luminosities and extended luminosities,and investigated the relationship between core-dominated parameter and the core,and extended luminosities,and as well as between core-dominated parameter and redshift.The results show that there is a clear correlation between the core-dominated parameter and core luminosities,and an anti-correlation between core-dominated parameter and extended luminosities.However,there is a weak or even no correlation.This is consistent with the results reported by Fan and Zhang(2003).The correlation between core-dominated parameter and the core and extended luminosities can be explained by the beaming effect.更多还原
