| 摘 要： | 考虑了观测到的Ｂｌａｚａｒｓ多波段辐射的两分量特征，提出该观测特征可由频率相并的聚束效应和内禀谱一起来解释．多普勒因子与频率之间的关系由分析观测数据获得．假定内禀谱由非均匀喷流中同步－自康普顿机制产生，应用该模型解释了３Ｃ２７９的辐射．

| Abstract: | e consider the observed two-component feature in the multiwavelength spectrum ofblazars and point out that this feature may be explained by a joint consideration of a beamingeffect with a frequency-dependent Doppler factor and the intrinsic spectrum. The frequencydependence of the Doppler factor is obtained by an analysis of the observed data and theilltrinsic spectrum is assumed to be produced by synchrotron self-Compton mechanism inan inhomogeneous jet. We apply our model to the radiation of 3C 279. |
