摘　　要：In the study of dilepton production of a baryon-rich quark-gluon fireball based on the full stopping scenario via a relativistic hydrodynamic model,it is found that for the fixed initial baryon chemical potential with increasing initial temperature a peak indicating the formation of the baryon-rich quark-gluon matter appears in the total dilepton yield.
