China (Received 1999 May 7; accepted 1999 June 27) Abstract A study of Doppler-boosting effect on the fluxes of active galactic nuclei (AGNs) with relativistic bulk motion is presented. Four AGNs samples (the BL Lacertae object sample, the core-dominated high-polarization quasar sample, the core-dominated low-polarization quasar sample, and the lobe- dominated quasar sample) presented by Ohisellini et al. (1993, AAA 57. 158. 207), are employed. All plots of radio flux versus optical flux, corrected by Doppler factors, for the four samples exhibit an obvious correlation between the two quantities, in agreement with what would be predicted by the synchrotron-emission mechanism. The results show that Doppler-boosting effect is indeed obvious for the AGNs with relativistic bulk motion. Key words: BL Lacertae objects: general Galaxies: nuclei - Quasars: general - Radiation mechanisms: nonthermal - Relativity
