我们提出了一个分子机器能量转换的动力学机制，通过考虑一个简单的模型来描述两个组成部分，头和链的动力学。在向头部区域注入能量后，能量在一个部位储存一段时间，并逐步使用，使头部在波动的环境下沿链定向移动，而不管输入的方向如何。我们的系统可以利用内部动力学和组件的灵活性来调整头部穿越能量障的时间。对分子机器提出了一些建议。
We propose a dynamical mechanism of a molecular machine for energy conversion, by considering a simple model describing the dynamics of two components, the head and the chain. After injection of energy to the head region, the energy is stored at one part for some time, and is used step by step, allowing the head to move directionally along the chain, irrespective of the direction of the input, under a fluctuating environment. Our system can adjust the timing with which the head crosses the energy barrier by taking advantage of internal dynamics and the flexibility of components. Some suggestions are given for molecular machines.
