摘要翻译:
在稀释准理想玻尔兹曼近似下,一个Lennard-Jones系统的膨胀动力学,首先在高密度下被限制,然后在真空中自由膨胀,面对的是一个膨胀的统计系综,该系综是在稀释准理想玻尔兹曼近似下导出的。事实证明,这种描述在预测平均一体全球可观测物方面是相当准确的,但在事件的构型空间结构中观察到了重要的偏差。概述了有限扩展物理系统的可能含义。

英文摘要:
The dynamics of the expansion of a Lennard-Jones system, initially confined at high density and subsequently expanding freely in the vacuum, is confronted to an expanding statistical ensemble, derived in the diluted quasi-ideal Boltzmann approximation. The description proves to be fairly accurate at predicting average one-body global observables, but important deviations are observed in the configuration-space structure of the events. Possible implications for finite expanding physical systems are outlined.
