| Abstract: | The effective potential of the nontopological soliton model is calculated at finite temper- ature and density.The tempreature and the chemical potential dependence of the bag constant is ob- tained.The feature of deconfinement phase transition is analysed.It turns out that,in this model,the deconfinement phase transition is of first order,the analysis of the phase transition feature suggests the coexistence of deconfinernent phase and confinement phase. |
