摘要翻译：
数值研究了小团簇在热涨落作用下的碰撞现象。通过对两个相同团簇碰撞的分子动力学模拟，发现当碰撞速度小于团簇中一个原子的热速度时，迎头碰撞的恢复系数可以超过1。平均行为可以用冲击现象的准静态理论来理解。同时也证实了我们的结果受涨落定理的支配。

英文摘要：
  Impact phenomena of small clusters subject to thermal fluctuations are numerically investigated. From the molecular dynamics simulation for colliding two identical clusters, it is found that the restitution coefficient for head-on collisions can exceed unity when the colliding speed is smaller than the thermal velocity of one ``atom'' of the clusters. The averaged behavior can be understood by the quasi-static theory of impact phenomena. It is also confirmed that our result is governed by the fluctuation theorem.
