The calculation method of AGN γ-ray emission flux

Based on a power-low spectrum of AGN γ-ray emissions,the calculation method by using the γ-ray integral photon fluxes to calculate total flux density of γ-ray,flux density at E GeV,average flux density,total luminosity,average luminosity and luminosity at E GeV were discussed,and their corresponding calculation equation were put forward.The γ-ray emission flux density,luminosity parameter etc.were calculated using those equations presented in this paper for 4 Fermi Blazars.In other bands as radio,X-ray etc.,the calculation method of flux density and luminosity can use this method too,if their emissions are power-low.
