| 英文摘要 | The improved quark mass density-dependent model (IQMDD) based on soliton bag model is studied at finite temperature. Applying the finite temperature field theory, the effective potential of the IQMDD model and the bag constant B(T) have been calculated at different temperatures. It is shown that there is a critical temperature T-C similar or equal to 110 MeV. We also calculate the soliton solutions of the IQMDD model at finite temperature. It turns out that when T < T-C, there is a bag constant B(T) and the soliton solutions are stable. However, when T > T-C the bag constant B(T)=0 and there is no soliton solution, therefore, the confinement of quarks are removed quickly. |
