| 英文摘要 | The phase transition of hadronic to quark matter and the boundaries of the hadron-quark coexistence phase are studied within the two equation of state (eos) models. the relativistic effective mean-field approach with constant and density-dependent meson-nucleon couplings is used to describe hadronic matter, and the mit-bag model is adopted to describe quark matter. the boundaries of the mixed phase for different bag constants are obtained solving the gibbs equations. we notice that the dependence on the bag parameter of the critical temperatures (at zero chemical potential) can be well reproduced by a fermion ultrarelativistic quark gas model, without contribution from the hadron part. at variance, the critical chemical potentials (at zero temperature) are very sensitive to the eos of the hadron sector. hence, the contribution of the hadronic interaction is much more relevant for the determination of the transition to the quark-gluon plasma at finite baryon density and low t. moreover, in the low-temperature and finite chemical potential region no solutions of the gibbs conditions are existing for small bag-constant values, b < (135mev)(4). isospin effects in asymmetric matter appear important in the high chemical-potential regions at lower temperatures, of interest for the inner-core properties of neutron stars and for heavy-ion collisions at intermediate energies. |
