摘　　要：用微观动力学模型研究了中高能核反应中的热化．对８３０ＭｅＶｐ＋５６Ｆｅ和３５ＭｅＶ／ｕ４０Ｃａ＋４０Ｃａ反应的研究表明，反应系统基本上达到了统计热平衡．发现两核碰撞过程中存在明显的横向流．Thermalization in intermediate high energy reaction is studied by microscopic kinetic model. The calculations are carried out for reactions 830 MeV p+ 56 Fe and 40 Ca ( E =35 MeV/u )+ 40 Ca. The calculations show that the quasi equilibrium can be reached. It is found that there is an obvious transverse flow in the nucleus nucleus reaction process.

关 键 词：中高能 核反应 热化 横向流
