英文摘要	We present optical spectroscopic observations of SS 433 during different precessional and orbital phases. Our 2004, 2007 and 2008 data provide us a good chance to study the variability of the Ha line at different orbital phases for nearly the same disk inclination. The data show that the Ha of SS 433 usually had a symmetric profile between orbital phases 0.25-0.75, while an asymmetric structure with a strong red peak was observed for other orbital phases. We suggest that the orbital variability of Ha emission is connected with accretion flow from the donor star to the accretion disk. In addition, we attribute the dramatic increase of Ha emission during our 2007 observational run, which had a time scale of one day, to the emergence of strong jets.
