| 摘 要： | The question whether the radio properties of quasars are related to the mass of the central black hole or the accretion rate is important for our understanding of the formation of relativistic jets, but no consensus has been reached from statistical analyses. Using two large quasar samples, one radio-selected, one optical-selected, we re-exarnined these relations and find that previous differences between radio- and optical- selected samples can be ascribed, at least partly, to the effect of the narrow line component. All previous claimed correlations are much weaker, if exist at all.

| Abstract: | The question whether the radio properties of quasars are related to the mass of the central black hole or the accretion rate is important for our un-derstanding of the formation of relativistic jets,but no consensus has been reached from statistical analyses.Using two large quasar samples,one radio-selected,one optical-selected,we re-examined these relations and find that previous differences between radio-and optical-selected samples can be ascribed,at least partly,to the effect of the narrow line component.All previous claimed correlations are much weaker,if exist at all. |
