| 摘 要： | 在研究气体小体积元的涨落时,传统的关于大系统的平衡涨落结果是不够的.本文首先利用平均自由程方法说明了相邻的小单元之间由关联导致的对气体涨落修正的物理机制,然后运用气体输运方法计算了精确的修正结果. |

| Abstract: | Classical theory of equilibrium fluctuations in large systems is not adequate when small volume situation is encountered.We use the mean free path approach to illuminate the physical picture of the correction to the fluctuations of gas caused by the correlation between neighboring small cells,and then calculate the exact correction by using theory of transport processes in gas. |
| Keywords: | thermodynamics and statistical physics fluctuations correlation |
