Based on 395 late-type spiral galaxies brighter than 15 mag in r-band that selected from Data Release Two of Slogan Digital Sky Survey, we decompose their bulges and disks through one-dimensional fitting of the surface brightness profile, and statistically analyze the color gradients in their disks.
从Sloan巡天第二批释放的数据(Sloan Digital Sky Survey, Data Release Two)中选择了395个在r波段亮于15 mag的晚型旋涡星系作为样本，对样本星系的表面亮度轮廓进行一维两成分(核球与盘)拟合，并着重讨论了盘的颜色梯度，分别用Δc／ΔR和Δc／Δlg R两种形式来拟合。
