摘要: 研究了驱动马达与轨道之间纳米摩擦的微观机制.通过基于克拉默斯(Kramers)理论的"键断裂"模型,得到了驱动马达与轨道之间纳米摩擦与马达行走速度之间关系.研究表明我们的理论结果与实验吻合.

关键词: 驱动马达, 纳米摩擦, 键断裂模型

Abstract: The nano-friction between Kinesin and microtubule is investigated. By using the rupture bond model based on the Kramers theory, we obtain the nonlinear relationship between friction and velocity. Our theoreticalresults are in agreement with experimental data.

Key words: Kinesin, nano-friction, rupture bond model
