Based on the beaming model, a relation between the observed polarization and Doppler factor was obtained for BL Lacertae objects–BLs by Fan et al. (1997). If flat spectral radio quasars—FSRQs fit a similar polarization-Doppler factor relation as BLs, then we can find that the ratio, f, of the de-beamed jet luminosity to the unbeamed luminosity in the source frame in BLs is greater than that in FSRQs. That difference in f is consistent with the result by Fan (2002a), which perhaps accounts for the emission line difference between BLs and FSRQs.
