我们考虑晶格气扩散动力学与创建湮灭在散装和保持平衡的两个水库在边界。这个随机粒子系统可以被看作是一个玩具模型的粒状气体的能量注入在边界和散在散装。计算了流过系统的粒子流的大偏差泛函，并讨论了一些物理结果：局部电流涨落机制、动力学相变、涨落关系。
We consider lattice gas diffusive dynamics with creation-annihilation in the bulk and maintained out of equilibrium by two reservoirs at the boundaries. This stochastic particle system can be viewed as a toy model for granular gases where the energy is injected at the boundary and dissipated in the bulk. The large deviation functional for the particle currents flowing through the system is computed and some physical consequences are discussed: the mechanism for local current fluctuations, dynamical phase transitions, the fluctuation-relation.
