Both the Lorentz factors (/') and viewing angles (0) are estimated for the 68 sources The relationship between BL Lacs and FSRQs is also revisited using the two variables off'and 0. The Lorenz factors are in the range of 2.33 to 64.07. The viewing angles are in the range of 0.04 to 24.56. The averaged value of the viewing angle for BL Lacs is slightly larger than that for FSRQs, while the averaged value of the Lorentz factor for BL Lacs is smaller than that for FSRQs.展开更多
