The effect of quenched disorder on the underdamped motion of a periodically driven particle on a ratchet potential is studied. As a consequence of disorder, current reversal and chaotic diffusion may take place on regular trajectories. On the other hand, on some chaotic trajectories disorder induces regular motion. A localization effect similar to the Golosov phenomenon sets in whenever a disorder threshold that depends on the mass of the particle is reached. Possible applications of the localization phenomenon are discussed.
研究了猝灭无序对周期驱动粒子在棘轮势上欠阻尼运动的影响。由于无序，电流反转和混沌扩散可能在规则轨迹上发生。另一方面，在一些混沌轨迹上无序会诱导规则运动。每当达到取决于粒子质量的无序阈值时，就会出现类似于戈洛索夫现象的局域化效应。讨论了局域化现象的可能应用。
