摘要翻译：
我们用Langevin动力学模拟研究了聚合物-孔相互作用对易位动力学的影响。一个有吸引力的相互作用可以大大提高易位概率。同时，对弱吸引物来说，易位时间增长缓慢，而对强吸引物来说，易位时间呈指数依赖性。在固定驱动力和链长的情况下，易位时间直方图随吸引力的增加由高斯分布向长尾分布过渡。在较弱的驱动力和较强的吸引力作用下，转位时间和在孔中的停留时间都表现出与链长的非单调关系。我们的模拟结果与最近的实验数据符合得很好。

英文摘要：
  We investigate the influence of polymer-pore interactions on the translocation dynamics using Langevin dynamics simulations. An attractive interaction can greatly improve translocation probability. At the same time, it also increases translocation time slowly for weak attraction while exponential dependence is observed for strong attraction. For fixed driving force and chain length the histogram of translocation time has a transition from Gaussian distribution to long-tailed distribution with increasing attraction. Under a weak driving force and a strong attractive force, both the translocation time and the residence time in the pore show a non-monotonic behavior as a function of the chain length. Our simulations results are in good agreement with recent experimental data.
