BL Lac Objects and Acceleration Model (Ⅱ)

A complete sample of RBLs with strong beam effect (ie. δ>1.0 and f_5GNz>1Jy)is given in this paper. Based on the acceleration model and known Doppler factors, the corrected data show much better correlations of multiwavelength than the observed ones. Particularly the effective spectral index corrected for RBLs is almost the same as that of XBLs within the error box, which suggerst that RBLs XBLs belong to a single class. Besides, the superluminal motion and the γ-emission are also discussed, Resucts show that the γ-ray is also an indicator of beaming model as well as superluminal motion.
