摘要翻译：
本文观察到并提出了一种囚禁机制，认为这是最近在存在淬火噪声的外部振荡驱动下，过阻尼棘轮输运特性中发现的反常行为的根源。特别地，当猝灭无序强度大于阈值时，这种机制就会出现。通过研究一个无序位形空间中的陷阱结构，确定了陷阱存在所需的最小无序强度。本文得到了一个完全棘轮格子中包含的有限长无序区域中俘获概率密度函数的近似。由于陷阱的存在，粒子的平均速度和扩散系数与淬灭噪声强度有非单调的依赖关系。

英文摘要：
  A trapping mechanism is observed and proposed as the origin of the anomalous behavior recently discovered in transport properties of overdamped ratchets subject to external oscillatory drive in the presence of quenched noise. In particular, this mechanism is shown to appear whenever the quenched disorder strength is greater than a threshold value. The minimum disorder strength required for the existence of traps is determined by studying the trap structure in a disorder configuration space. An approximation to the trapping probability density function in a disordered region of finite length included in an otherwise perfect ratchet lattice is obtained. The mean velocity of the particles and the diffusion coefficient are found to have a non-monotonic dependence on the quenched noise strength due to the presence of the traps.
