本文研究了具有开边界和其它驱动随机格子气的粒子进入、跳跃和离开一维格子的非对称简单排斥过程。长期系统动力学、定态和定态之间相变的性质可以根据两个特征速度（集体速度和激波（畴壁）速度）的相互作用来理解。这种相互作用导致两种不同类型的畴壁，其动力学被计算。我们得出结论，ASEP的相图是通用的单组分驱动的晶格气体与一个最大的电流密度关系。
We consider the asymmetric simple exclusion process (ASEP) with open boundaries and other driven stochastic lattice gases of particles entering, hopping and leaving a one-dimensional lattice. The long-term system dynamics, stationary states, and the nature of phase transitions between steady states can be understood in terms of the interplay of two characteristic velocities, the collective velocity and the shock (domain wall) velocity. This interplay results in two distinct types of domain walls whose dynamics is computed. We conclude that the phase diagram of the ASEP is generic for one-component driven lattice gases with a single maximum in the current-density relation.
