论文摘要
每个统计力学学生都研究了刚性容器中理想气体中理想气体的平衡和波动。在这里，我们研究了盒子自由漂浮的鲜为人知的情况。特别是，由于与其中的气体相互作用，我们确定了盒子的波动。该系统是一个玩具模型，用于在银河系中心的恒星包围的黑洞的速度和位置波动。这些波动在附近的星系中可以观察到。
The equilibrium and fluctuations of an ideal gas in a rigid container are studied by every student of statistical mechanics. Here we study the less well-known case when the box is floating freely; in particular we determine the fluctuations of the box in velocity and position due to interactions with the gas it contains. This system is a toy model for the fluctuations in velocity and position of a black hole surrounded by stars at the center of a galaxy. These fluctuations may be observable in nearby galaxies.
