摘要
本文从相对论BUU理论出发研究了1GeV/n能区重离子反应全局(global)和局域(local)平衡性质,计算表明在该能区平均场对反应动力学过程仍有相当的作用;对有限核系统的反应动力学过程的时间演化的研究表明,有限核系统无论全局的还是局域的平衡均未能达到完全平衡,因而对有限核系统重离子反应基于完全热平衡概念的适用性值得怀疑.
The equilibration in relativistic heavy ion collisions ie studied with relativistic BUU theory.It is found that the mean field still play an important role in addition to the collison term of the equilibration process in relativistic heavy ion collisions at energy arround 1GeV/n.The influence of the medium effects is studied.The light and medium systems do not reach complete equilibrium so that the concept based on the complete equilibrium is questionable for this case.
