Abstract

In this paper, by using of the UMRAO database, the correlation between the radio flux density and polarization degree of Quasar 3C 273 (including 4. 8, 8 and 14. 5 GHz) is studied. The results show that the polarization degree is strongly anti-correlated with the radio flux density at all the three frequencies. The strong anti-correlations seem to show that the flux density and polarization variations of 3C 273 are not related to the beaming effect. It is suggested that these phenomena could be explained by the two-component model, that is, these anti-correlations between flux density and polarization degree result from shock waves propagating in a magnetized jet on the condition that the polarization angles of the jet component and the shock component are approximately perpendicular to each other and have similar polarization degrees.
