| 摘 要： | 从理论上讨论了在二维少体刚性圆盘系统中,“绝热塞子”在位形空间中的统计分布,发现了一个很有趣的反直觉的“双蜂”分布现象,之后对这样一个系统进行了数值模拟,得到的模拟结果与理论结果非常一致。

| Abstract: | Spatial probability distributions of few-body "adiabatic piston" system in two-dimensional box are analytically computed in statistical equilibrium states, and explicit solutions of the probability distributions are obtained. Some nontrivial interesting features of the probability distributions are predicted, and fully confirmed by numerical simulations. And the realization of micro-canonical equilibrium state of the system is justified by the agreement between the theoretical predictions and numerical observations. |
