摘要
In this work, we determine the central black hole mass for a sample of blazars including 30 gamma-ray loud blazars with available variability timescales. The gamma-ray energy, the emission size and the property of a two-temperature accretion disk are used to determine the absorption depth. If we take the intrinsic gamma-ray luminosity to be lambda times the Eddington luminosity, i.e. L-gamma(in) = lambda L-Edd, then we have following results: the masses of the black hole are in the range of 0.59 similar to 67.99 x 10(7) M-circle dot(lambda = 1.0) or 0.90 similar to 104.13 x 10(7)M(circle dot)(lambda = 0.1). Blazars are also discussed.
