摘要: The influence of the dissipative terms on conditions formation and characteristic parameters shock waves in relativistic nuclear collisions is investigated for three types equation state (non linear QHD-1, resonance gas lattice QCD). Energy velocity profiles are obtained a one-dimensional model; duration phase width front calculated. It shown that presence transition results strong enhancement front, which an increase transparency. This effect, combined with fact nuclei have finite size, prevents energy density to rise its maximum value (full stopping) as would be predicted by non model.
