Based on the revers kinetic intermediate energy heavy ion collision in which much more intermediate mass fragments are emitted towards forward angles , a sensitive observable on isospin effects in heavy ion collisions is investigated by means of using isospin dependent quantum molecular dynamics ( iqmd ) 摘要在重离子碰撞过程中，基于重质量的弹核轰击轻质量靶核有大量中等质量碎片向前发射的逆运动学效应，利用同位旋相关的量子分子动力学观察和研究了重离子碰撞过程中同位旋效应的灵敏性。
