摘　　要：在量子分子动力学模型框架下,研究了10—100MeV/A能区重离子碰撞的动力学过程;计算了集团的质量分布及其随时间的演化,以及密度分布随时间的发展。同时预言了该能区的反应机制及其特征,并与BUU模型作了比较。The dynamical process of heavy ion collisions in the energy region of 10 to 100 MeV/A has been investigated by Quantum Molecular Dynamics model. According to the calculated mass distribution of clusters, the time evolution of mass 'distribution and density distribution, the reaction mechanism and its characteristic are predicted and compared with those obtained from the BUU model.
