中文摘要：

在量以内分子的动力学(QMD ) 模型，动态 octupole 变丑在重离子的熔化反应的来临的过程作为在射弹和目标之间的中央距离的功能被学习。事件精力上的最大的动态 octupole 变丑的依赖也被调查。动态 octupole 变丑能在来临的过程期间被观察，并且最大的动态 octupole 变丑与减少的事件精力变得更重要。在射弹和目标的质子和中子中心的分布也分别地被调查。在重离子的熔化反应的来临的过程，因为强壮的库仑潜力，在二个原子核的质子中心之间的分离在中子中心之间比那大。

英文摘要：

Within the quantum molecular dynamics （QMD） model, the dynamical octupole deformation is studied as a function of the central distance between the projectile and target in the approaching process of heavy-ion fusion reactions. The dependence of the maximum dynamical octupole defor- mations on tile incident energies is also investigated. The dynamical octupole deformations can be observed during the approaching process, and the maximum dynamical octupole deformations be- come more significant with decreasing incident energies. The distributions of the proton and neutron centers in the projectile and target are also investigated, respectively. In the approaching process of heavy-ion fusion reactions, the separation between proton centers for two nuclei is larger than that between neutron centers because of the strong Coulomb potential.
