英文摘要	We have analyzed a large sample of FSRQs detected by Fermi LAT. Our main intents are to investigate the relations between bulk Lorentz factor and black hole mass, between bulk Lorentz factor and Eddington ratio. Using archive and calculation, we obtained the distributions of bulk Lorentz factor, black hole mass and Eddington ratio. After excluding redshift effect, there is still significant correlation between bulk Lorentz factor and black hole mass, but not correlation between bulk Lorentz factor and Eddington ratio, which suggest that faster jets have a close relation with more massive black holes, and the Blandford-Znajek (BZ) mechanism may dominate over the Blandford-Payne (BP) mechanism for Fermi FSRQs.
