Co-variability Between the Broad Absorption Lines and Narrow Absorption Lines
《Research in Astronomy and Astrophysics》2024年第9期99-105,共7页Bo-Lin Qin Jing Li Wei-Jian Lu 
supported by the Guangxi Natural Science Foundation(No.2021GXNSFBA220044);the National Natural Science Foundation of China(No.11903002);the Research Project of Baise University(No.2019KN04)。
We investigate the relationship between the variability of broad absorption lines(BALs)or narrow absorption lines(NALs)and that of continuum using a data set of two-epoch SDSS spectra containing 134 C IV NAL-BAL pairs...
