摘要: We study the statistics of power flux into a collection inelastic beads maintained in fluidized steady state by external mechanical driving. The shows large fluctuations, including frequent negative about its average value. relative probabilities positive and fluctuations are close accord with fluctuation theorem Gallavotti Cohen, even at time scales shorter than those required theorem. also compare an effective temperature that emerges from this analysis to kinetic granular temperature.
