一个理想气体系统，要达到热平衡，可以通过分子之间的碰撞，
或者通过和热库接触。我现在是想碰撞过程。假设两体碰撞不存在，
那么系统还可以达到平衡状态嘛？ 是不是三体碰撞的T太长，
以至于碰撞不足以抵消涨落？
平衡状态is a statistical defination. It depends on the interaction of
particles you have in a system. If 两体碰撞不存在, there is no [enough]
interaction, and there is no 平衡状态. Consider this: what is the temperature
of a single atom? You may have a high energy an |
