收集了89个 Seyfert星系样本,利用反响映射法和恒星弥散速度法计算了 Seyfert 星系的黑洞质量,分别研究了 Seyfert 1和 Seyfert 2星系的黑洞质量与吸积率、热光度和红移之间的相关性,结果发现Seyfert 1星系的黑洞质量与吸积率、热光度和红移之间具有强相关性,Seyfert 2星系的黑洞质量与吸积率之间具有弱的负相关性,与热光度和红移之间具有弱相关性。两类 Seyfert 星系的区别除了源于吸积盘倾角不同外,还可能与星系的环境、演化和星系核的活动有关。
收集瞭89箇 Seyfert星繫樣本,利用反響映射法和恆星瀰散速度法計算瞭 Seyfert 星繫的黑洞質量,分彆研究瞭 Seyfert 1和 Seyfert 2星繫的黑洞質量與吸積率、熱光度和紅移之間的相關性,結果髮現Seyfert 1星繫的黑洞質量與吸積率、熱光度和紅移之間具有彊相關性,Seyfert 2星繫的黑洞質量與吸積率之間具有弱的負相關性,與熱光度和紅移之間具有弱相關性。兩類 Seyfert 星繫的區彆除瞭源于吸積盤傾角不同外,還可能與星繫的環境、縯化和星繫覈的活動有關。

In this paper, we collected 89 samples of Seyfert galaxies, calculated the black hole mass of Seyfert galaxies using the reverberation mapping method and the central velocity disper-sion respectively,and studied the correlation between the black hole mass of Seyfert 1 and Sey-fert 2 galaxies,accretion rate,bolometric luminosity and the redshift.There are strong correla-tions between black hole mass of Seyfert 1 and accretion rate,between the black hole mass of Seyfert 1 and the bolometric luminosity,and between the black hole mass of Seyfert 1 and the redshift,while there are weak negative correlation between the black hole mass of Seyfert 2 and the accretion rate,weak correlation between the black hole mass of Seyfert 2 and the bolometric luminosity,and between the black hole mass of Seyfert 2 and the redshift.The differences be-tween the two kinds of Seyfert galaxies not only be due to the different aspect angles,may also be due to the environment,the evolution of galaxies and activities of galaxies nuclear.
