Abstract：
The (1+1) dimensional relativistic hydrodynamics equation with a source term including quark-fragment effects is numerically solved and the evolution of energy density, flow rapidity, and baryon number density as the characteristic values of the phase transition possibly produced in nuclear collisions at extreme high energy are also analyzed. The quark-fragment effects in the source term are described by using the phenomenological SU/(3) string model with a flavor dynamics.
The numerical results are compared with Kajantie's data. It illustrates indirectly that the results are consistent with the experimental data. The physics picture of our model presented in this paper shows that the phenomenological self-consistent model is reasonable.
