导出了二维绝热活塞运动的封闭确定性方程。它预测活塞朝向最终静止位置的衰减振荡运动，这取决于初始状态。在大活塞质量极限下，该方程的解与硬盘分子动力学和流体力学的结果在定量上是一致的。
We derive a closed deterministic equation for the motion of the two-dimensional adiabatic piston. It predicts a damped oscillatory motion of the piston towards a final rest position, which depends on the initial state. In the limit of large piston mass, the solution of this equation is in quantitative agreement with the results obtained from both hard-disk molecular dynamics and hydrodynamics.
