英文摘要	In a sample of 60 quasars selected from the Sloan Digital Sky Survey (SDSS) with at least six-epoch spectroscopy, we investigated the variability of emission lines and continuum luminosity. In this paper, we present the results of SDSS J030639.57 + 000343.1. We found a strong anticorrelation between the continuum luminosity at 5100 and the spectral index, implying a bluer-when-brighter trend. The luminosity of the broad Ha line is in proportion to the continuum luminosity at 5100. Correspondingly, we did not find a strong correlation between the equivalent width of broad Ha and the continuum luminosity, i.e. no Baldwin effect of broad Ha in this source.
