摘要
本文在切仑柯夫线辐射理论模型基础上,讨论了类星体及赛佛特星系在3000附近的小鼓包.认为类星体及赛佛特星系的3000附近的连续谱由非热的幂律谱、吸积盘的黑体谱、宽线区小云的黑体谱及FeII线构成.对赛佛特星系NGC4151作了数值计算表明:理论与观测结果是相符的.同时,对切仑柯夫线辐射理论也是有力的支持.
Based on the Cerenkov line emission theory, this paper discusses the small 3000 bump in quasars and seyfert galaxies. It seems that the continuum spectrum of quasars and seyfert galaxies around 3000 is composed of power law, blackbody from accretion disk, blackbody from broad line region and Fell lines. Numerical calculation for seyfert galaxy NGC4151 shows that the theoretical result is in agreement with observations. On the other hand, this is also a strong support to the cerenkov line emission theory.
