基于外康普顿模型，通过对193个伽玛射线空间望远镜探测的平谱射电类星体的外光子场进行研究，结果表明：（1）逆康普顿散射峰值的光度和同步辐射峰值的光度之比LIC／LS 与逆康普顿峰频率和同步峰频率之比νIC／νS 呈负相关；（2）逆康普顿散射峰值的光度和同步辐射峰值的光度之间具有强的相关性，并且logLIC＝1.05logLS－1.58；（3）对于大部分Fermi平谱射电类星体，逆康普顿散射峰值的光度大于同步辐射峰值的光度。这些结果说明平谱射电类星体的种子光子除了来自宽线区外，还可能来自其它区域，并且与喷流的运动和磁场以及外部光子的能量密度有关。

Based on the model of External Compton ( EC) photons, we have collected a sample of 193 Flat Spectrum Radio Quasars ( FSRQs) observed by the Fermi Large Area Telescope and explored the properties of the external photon fields (as radiation seeds) in them.The results of our study are as follows.(1) There is an anti-correlation between (LIC/LS) and (νIC/νS) in our sampled FSRQs.Here, the (LIC/LS) is the ratio of the peak luminosity of inverse Compton scattering radiation to that of synchrotron radiation;the (νIC/νS ) is the ratio of the peak frequency of inverse Compton scattering radiation to that of synchrotron radiation.( 2) The peak luminosities of inverse Compton scattering radiation are strongly correlated with those of synchrotron radiation in the FSRQs.(3) In most FSRQs the peak luminosities of inverse Compton scattering radiation are above those of synchrotron radiation.The results show that in FSRQs photons as radiation seeds may be from broad-line regions as well as additional regions, and jet motions are related to the magnetic fields/external-photon energy densities.
