摘要
Based on the Cerenkov line-emission theory, this paper estimates the Cerenkov red-shifts of Balmer lines and gives a better explanation of the observations, that is, the high-ionization broad emission lines of quasars are blueshifted with respect to the neutral hy-drogen and the low-ionization broad lines.
