摘要 基于伽玛射线辐射的幂律谱规律,讨论了将观测的伽玛辐射积分光子流量转换成γ辐射总流量、E GeV处流量密度、平均流量密度、总光度、平均光度及E GeV处光度的计算方法,并给出了详细计算公式.用得到的公式计算了4个Fermi Blazars的γ辐射流量、光度等参量.如果在其他波段(如:射电、X射线)的辐射也是幂律的,则其流量和光度也可以用类似的方法计算. 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.
