标题： Breaking down the Fermi acceleration with inelastic collisions

摘要： 费米加速现象在具有外部随机扰动的耗散弹跳球模型中得到探讨。 结果显示，引入能量耗散（粒子与运动壁的非弹性碰撞）是破坏费米加速过程的充分条件。 表征了在耗散趋于零极限下，从有限能量增长到无限能量增长的相变。 显示英文摘要

摘要： The phenomenon of Fermi acceleration is addressed for a dissipative bouncing ball model with external stochastic perturbation. It is shown that the introduction of energy dissipation (inelastic collisions of the particle with the moving wall) is a sufficient condition to break down the process of Fermi acceleration. The phase transition from bounded to unbounded energy growth in the limit of vanishing dissipation is characterized.
