The dynamics of exotic hypernuclei in heavy-ion collisions has been investigated thoroughly with Lanzhou quantum molecular dynamics model. All possible channels on hyperon ($\Lambda$, $\Sigma$ and $\Xi$) production near threshold energies are implemented in the transport model. The light complex fragments (Z$$2) are constructed with the Wigner-function method. The classical phase-space coalescence is used for recognizing heavy nuclear and hyperfragments and the statistical model is taken for describing the decay process. The nuclear fragmentation reactions of the available experimental data from the ALADIN collaboration are well reproduced by the combined approach. It is found that the in-medium potentials of strange particles influence the strangeness production and fragment formation. The hyperfragments are mainly created in the projectile or target-like rapidity region and the yields are reduced about the 3-order magnitude in comparison to the nuclear fragments. The hypernuclear dynamics of HypHI data is well described with the model. The possible experiments for producing the neutron-rich hyperfragments at the high-intensity heavy-ion accelerator facility (HIAF) are discussed. (s)] , ,

重离子碰撞中外来超核的形成和动力学

利用兰州量子分子动力学模型对重离子碰撞中奇异超核的动力学进行了深入研究。Hyperon上的所有可能通道（$\Lambda$， $\Sigma$ 和 $\Xi$）在运输模型中实现了接近阈值能量的生产。轻的复杂片段（Z $$ 2）使用维格纳函数方法构造。经典的相空间合并用于识别重核和超碎片，并采用统计模型来描述衰变过程。结合的方法很好地再现了ALADIN合作提供的可用实验数据的核碎裂反应。发现奇特粒子的中等电势会影响奇特产生和碎片形成。超碎片主要是在弹丸或类似目标的快速区域中产生的，与核碎片相比，产量降低了约3个数量级。该模型很好地描述了HypHI数据的超核动力学。讨论了在高强度重离子加速器设施（HIAF）上产生富中子超碎片的可能实验。（s）] 、、
