摘要 活动星系核的演化研究在能量产生、辐射机制等基本问题的研究中占有重要的地位。首先对活动星系核的基本性质及分类进行了简单的介绍,然后根据搜集到的数据,通过分析发光度、中心黑洞质量、吸积率与红移的关系图,进一步支持了活动星系核的演化存在的两个演化序列的观点:一个是平谱射电类星体FSRQ逐步过渡到BL Lac天体,然后过渡到射电星系RG,最后过渡到椭圆星系;另一个是从类星体Quasars过渡Seyfert星系,然后过渡到正常漩涡星系。 The study on the property of AGNs is importance.In this paper,we briefly introduced the basic properties of AGNs.And then the paper mainly analyzed the redshift,the bolometric luminosity,the accretion rate and the masses of black hole.Finally,these results illustrated that the evolution ofAGNs could be divided into two sequences.One is from FSRQ to BL Lac to Radio galaxy to elliptical spiral galaxies,and the other is from Quasar to Seyfert galaxy to normal spiral galaxies.
