摘要翻译：
我们通过数值和大量的模拟研究了空间无序跳跃速率的猝灭对开边界非对称简单排斥过程(ASEP)特性的影响。在不同的输入和输出速率下，得到了体积密度和电流的无序平均值。我们研究了无序的二元分布和均匀分布。结果表明，空间不均匀性的影响一般是增大最大电流相位的大小。这与Harris和Stinchcombe的平均场结果一致。此外，我们还得到了电流和体密度对无序分布函数特性的依赖关系。结果表明，无序的影响主要取决于粒子的输入和输出速率。在某些情况下，无序可以建设性地增强电流。

英文摘要：
  We investigate the effect of quenched spatial disordered hopping rates on the characteristics of the asymmetric simple exclusion process (ASEP) with open boundaries both numerically and by extensive simulations. Disorder averages of the bulk density and current are obtained in terms of various input and output rates. We study the binary and uniform distributions of disorder. It is verified that the effect of spatial inhomogeneity is generically to enlarge the size of the maximal current phase. This is in accordance with the mean field results obtained by Harris and Stinchcombe. Furthermore, we obtain the dependence of the current and the bulk density on the characteristics of the disorder distribution function. It is shown that the impact of disorder crucially depends on the particle input and out rates. In some situations, disorder can constructively enhance the current.
