摘要翻译：
本文给出了存在集体运动的有限无束缚系统的统计处理，并将其应用于经典的Lennard-Jones哈密顿量，通过分子动力学进行了数值模拟。在理想气体极限下，流动动力学可以精确地重新浇铸成作用于标准吉布斯系综的有效时间相关拉格朗日参数，并附加总能量守恒约束。用同样的ansatz对相互作用膨胀系统的低密度冻结构型进行分析，我们发现流动的存在对微态分布有很大的影响。

英文摘要：
A statistical treatment of finite unbound systems in the presence of collective motions is presented and applied to a classical Lennard-Jones Hamiltonian, numerically simulated through molecular dynamics. In the ideal gas limit, the flow dynamics can be exactly re-casted into effective time-dependent Lagrange parameters acting on a standard Gibbs ensemble with an extra total energy conservation constraint. Using this same ansatz for the low density freeze-out configurations of an interacting expanding system, we show that the presence of flow can have a sizeable effect on the microstate distribution.
