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.
