从斯隆数字巡天(SDSS)收集了214个Seyfert 1星系, 其中147个窄线的Seyfert 1星系(NLS1s), 67个宽线的Seyfert 1星系(BLS1s), 对其黑洞质量、核球速度弥散、爱丁顿比、5100 Å光度、红移进行了研究, 得到以下结论: 1)在进行黑洞质量估算时, 应考虑辐射压的影响, 特别是窄线Seyfert 1星系; 2)在考虑辐射压的情况下, 窄线Seyfert 1星系满足近距正常星系的MBH-σ关系, 其吸积未超爱丁顿极限吸积; 3)在大样本下Seyfert 1星系从窄线Seyfert 1星系到宽线Seyfert 1星系演化, 与他人用其他方法获得的结果是一致的.

We collect 214 Seyfert 1 galaxies(147 narrow line Seyfert 1 and 67 broad line Seyfert 1) and research black hole mass bulge velocity dispersion Eddington radio luminosity at 5100 Å and redshift. Our conclusions are follows: (1) when computing black hole mass, we should consider the effect of radiation pressure, especially for the narrow line Seyfert 1 galaxies; (2) when the effect of radiation pressure is considered, narrow line Seyfert 1 galaxies meet MBH-σ relation of normal galaxies and are in su-Eddington accretion; (3) in a large samples, the evolution of Seyfert 1 galaxies is from narrow line Seyfert 1 galaxies to broad line Seyfert 1 galaxies, which is consistent with other results obtained in different ways.-
