We study some statistical properties for the behavior of the average squared velocity-hence the temperature-for an ensemble of classical particles moving in a billiard whose boundary is time dependent. We assume the collisions of the particles with the boundary of the billiard are inelastic, leading the average squared velocity to reach a steady-state dynamics for large enough time. The description of the stationary state is made by using two different approaches: (i) heat transfer motivated by the Fourier law and (ii) billiard dynamics using either numerical simulations and theoretical description.
我们研究了一群在边界随时间变化的台球中运动的经典粒子的平均平方速度（即温度）行为的一些统计特性。我们假设粒子与台球边界的碰撞是非弹性的，这使得平均平方速度在足够长的时间后达到稳态动力学。通过两种不同的方法来描述稳态：（i）基于傅里叶定律的热传递；（ii）使用数值模拟和理论描述的台球动力学。
