论文摘要
通过分子动力学方法研究了Lennard-Jones簇的松弛过程，用于针对初始簇的不同相态的分子动力学方法。证明了孔隙弛豫特征对初始簇相状态的强依赖性。结果表明，对于最初的固体群集，系统可以达到亚稳态状态，其中孔径固定在一个离散值之一的情况下。这些值不取决于初始集群温度和大小。因此，已经证明，在各种簇大小中，固体簇“魔术”毛孔可以稳定形成亚稳态。
Process of relaxation of Lennard-Jones cluster with an intrinsic pore was investigated by molecular dynamics method for different phase states of an initial cluster. Strong dependence of pore relaxation character on the initial cluster phase state was demonstrated. It was shown that, for the initially solid cluster, the system can reach metastable state where pore radius is fixed at one of the discrete set of values. These values do not depend on initial cluster temperature and size. Thus, it was demonstrated that, in a wide range of cluster sizes, inside solid clusters "magic" pores can stabilize forming a metastable state.
