| Abstract: | We use the Cerenkov line radiation and the moving model of quasar to discuss the formation of some broad emission lines of quasars. Our calculated profiles and relative intensities of the lines are in good agreement with the observations. The Cerenkov line radiation may therefore be important in the formation of the emission lines. |
