| 摘 要： | 对214个SeyfertI星系（其中147个窄线SeyfertI星系（NLSIs），67个宽线Seyfert工星系（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Seyfert工星系到宽线SeyfertI星系演化，与他人用其他方法得到的结果是一致的。 |

| Abstract: | 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. |
