英文摘要:
The thermalization process of nuclear matter in the central fireball region of heavy-ion collisions is investigated by employing an extended Boltzmann-Uehling-Uhlenbeck model, namely, the van der Waals Boltzmann-Uehling-Uhlenbeck (VdWBUU) model. The temperature (T) is extracted by the quantum fermion fluctuation approach and other thermodynamic quantities, such as the density (rho), entropy density (s), shear viscosity (eta), isospin diffusivity (D-I), and heat conductivity (kappa), are also deduced. The liquidlike and gaslike phase signs are discussed through the behavior of the shear viscosity during the heavy-ion collision process in the VdWBUU model.
