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．
Based on the theory of relativistic BUU, the global and local equilibrium properties of heavy ion reactions in 1 GeV / n energy region are studied. The results show that the average field in this energy region still plays a significant role in the reaction kinetics. The research on the evolution of the kinetic process of nuclear systems shows that the equilibrium of the finite nuclear system can not be completely balanced both in the global and the local. Therefore, it is doubtful that the applicability of the perfect nuclear equilibrium system based on the concept of complete heat balance is concerned.
