From our results mentioned above, we can conclude that (1) polarization is correlated with the beaming effect and the continuous jet model may be more reasonable than the spherical model; (2) the large difference in the polarizations between RBLs and XBLs is from the difference in the beaming effect. (3) This scenario can explain the differences in luminosities, multiwavelength correlations, different spectral indices, and the difference in the polarizations between RBLs and XBLs, but the viewing angle effect alone cannot explain the spectral energy distribution between RBLs and XBLs (Sambruna et al. 1996).
