摘　　要：对214个SeyfertⅠ星系(其中147个窄线SeyfertⅠ星系(NLSⅠs),67个宽线SeyfertⅠ星系(BLSⅠs))的红移、热光度、爱丁顿比、黑洞质量的分布进行研究,并讨论了红移和热光度、爱丁顿比的关系。得到了以下结论:1)窄线SeyfertⅠ星系的红移、热光度、爱丁顿比都大于宽线SeyfertⅠ星系的红移、热光度、爱丁顿比;2)窄线SeyfertⅠ星系的黑洞质量小于宽线SeyfertⅠ星系的黑洞质量;3)在大样本下SeyfertⅠ星系从窄线SeyfertⅠ星系到宽线SeyfertⅠ星系演化,与他人用其他方法得到的结果是一致的。The distribution of the bolometric luminosity, redshift, Eddington ratio and the black hole mass of 214 Seyfert I galaxies（including 147 narrow line Seyfert I galaxies and 67 broad line Seyfert I galaxies）were studied and the relationships between bolometric luminosity and redshift, between red- shift and Eddington ratio were discussed. The results showed that： 1） The bolometric luminosity, redshi{t, Eddington ratio of the narrow line Seyfert I galaxies is greater than that of the broad line Seyfert I galaxies; 2） Black hole mass of the narrow line Seyfert I galaxies is less than that of the broad line Seyfert I galaxies; 3） On large numbers of samples, the evolutionary process of Seyfert galaxies is from the narrow line Seyfert I to the broad line Seyfert I, which is the same as others.
