论文摘要
计算和分析了对二维Yukawa系统熵的两体（配对）贡献。证明在流体 - 固体（冷冻）相过渡的附近，对熵在狭窄的温度范围内突然跳跃，这可用于识别冰点。简要讨论与全部过剩熵和一些现有的冻结指标的关系。
The two-body (pair) contribution to the entropy of two-dimensional Yukawa systems is calculated and analyzed. It is demonstrated that in the vicinity of the fluid-solid (freezing) phase transition the pair entropy exhibits an abrupt jump in a narrow temperature range and this can be used to identify the freezing point. Relations to the full excess entropy and some existing freezing indicators are briefly discussed.
