Abstract：
Taking the interactions between quarks into account, we study thermodynamics of strange quark matter system in the quasi-particle approximation with the result that an extra term should be added to the thermodynamic potential density considering the self-consistent condition. The equation of states turns out to be "softened" when applying the above thermodynamics to strange quark matter in strange stars, and this is consistent with the results of the mass chemical potential-dependent model. However, the quasi-particle description model indicates the dependence of medium effects on the coupling constant of strong interaction.
