摘要
活动星系核的高能辐射占了它们总辐射的相当大的比例。搜集了活动星系核的样本98个,通过分析谱指数、红移、流量密度来探讨活动星系核能谱演化。
The study of AGNs play an important role in the x-ray radiation and the gamma-ray radiation of AGNs is at a AGNs. In the paper, we collected the sample of 98 of AGNs. study of the origin of energy, the large percentage of all radiation of In order to making an initial statistical research for the AGNs evolution.
