摘要 采用活动星系核图像的核球/盘分解数据得到核球R波段光度值,计算了一个X射线活动星系核样本的中心大质量黑洞质量与核球质量之比(Mbh/Mbulge),其中包括15个窄线塞弗特1星系(NLS1 s)和18个宽线塞弗特1星系(BLS1 s).我们发现log(Mbh/Mbulge)的平均值,对15个窄线塞弗特1星系为:-3.81±0.11;而对18个宽线塞弗特1星系,则为:-2.91±0.13.这表明:窄线塞弗特1星系相对于宽线塞弗特1星系而言有较低的Mbh/Mbulge. Using the bulge data from AGNs image decomposition to get the bulge luminosity of R band, the ratio of the central supermassive black hole mass to the bulge masses （Mhh/Mbulge ） in a sample of X- ray selected AGNs was calculated, including 15 narrow-line Seyfert 1 galaxies （NLSls） and 18 broad-line Seyfert 1 （BLSls） galaxies. The mean value of log （Mhh/Mbulge） is -3. 81±0. 11 for 15 NLSls, and -2.91±0.13 for 18 BLSls, showing the lower Mhh/Mbulge in NLSls relative to BLSls.
