摘要：

Using three criteria, we discuss the observational distinction between relativistic beaming and pure accretion for 69 active galaxies, including Seyferts, Quasars, and BL Lac objects. The first criterion is whether the inferred efficiency of the conversion of accreted matter into energy is greater than 0.1 or not. The second one is whether the observed flux is larger than the classical Eddington luminosity or not. The third is concerned in the strong coupling of geometrical and physical effects in jets. The result suggests distinguishing active galactic nuclei into two types.
