主　　题：Chemical potential 

摘      要：Based on the Dyson–Schwinger approach, a method for obtaining the chemical potential dependence of the dressed quark propagator in the `Nambu–Goldstone and the `Wigner phase is developed. The bag constant in the presence of the non-zero chemical potential is analysed.
