摘要翻译：
当充填分数足够高时，两种物质的二维晶格气体在外力的驱动下，在相反的方向上发生干扰跃迁。利用蒙特卡罗模拟，我们研究了当系统从无序的初始状态接近非平衡稳态时，这些堵塞（“云”）的增长。我们监视动态结构因子$S(k_x,k_y；t)$并发现$k_x=0$分量表现出动态缩放，形式为$S(0,k_y；t)=t^\beta\tilde{S}(k_yt^\alpha)$。在相当长的时间范围内，我们观察到非常好的数据崩溃:$\alpha=1/2$和$\beta=1$。讨论了不同填充率和驱动力的影响。

英文摘要：
  A two-dimensional lattice gas of two species, driven in opposite directions by an external force, undergoes a jamming transition if the filling fraction is sufficiently high. Using Monte Carlo simulations, we investigate the growth of these jams ("clouds"), as the system approaches a non-equilibrium steady state from a disordered initial state. We monitor the dynamic structure factor $S(k_x,k_y;t)$ and find that the $k_x=0$ component exhibits dynamic scaling, of the form $S(0,k_y;t)=t^\beta \tilde{S}(k_yt^\alpha)$. Over a significant range of times, we observe excellent data collapse with $\alpha=1/2$ and $\beta=1$. The effects of varying filling fraction and driving force are discussed.
