主　　题：Ward-Takahashi identity Ball-Chiu vertex finite chemical potential 

摘      要：Based on the Ward-Takahashi identity at finite chemical potential and Lorentz structure analyms, we generalize the Ball-Chiu vertex to the case of nonzero chemical potential and obtain the general form of the frmionboson vertex in QED at finite chemical potential.
