中文摘要：

通过在同位旋相关量子分子动力学模型（IQMD）中引入同位旋依赖的动量相关作用和同位旋相关的Skyrme势,得到了改进的同位旋依赖的量子分子动力学模型,并用此模型分析和讨论了中能重离子碰撞中的同位旋分馏强度随入射道条件的演化.结果表明在中能重离子碰撞中各种入射道条件下同位旋依赖的动量相关作用和Skyrme势有着明显的同位旋效应,它们减弱了同位旋分馏的过程.

英文摘要：

Isospin degree of freedom is introduced in Skyrme potential and momentum dependent interaction to obtain the revised isospin dependent quantum molecular dynamics. The isospin effect of isospin fractionation ratio is studied for different beam energies and different colliding systems based on the revised isospin dependent quantum molecular dynamics. It is found that the isospin effect of isospin fractionation ratios is important for different incident channel conditions,for example,the isospin fractionation ratios for different incident channel conditions are reduced after the isospin degree of freedom in Skyrme potential and momentum dependent interaction are included. However, the isospin fractionation ratio is also sensitive to symmetry potential. In this case it is also a good probe for extracting information on the symmetry potential in heavy ion collisions.
