摘　　要：针对肌动蛋白两足交替行走的事实提出了Tilting ratchet双足运动模型,并对其运动轨道进行了数学模拟.从而说明所提出的模型能够清楚的描述这种交替行走的运动机制,表明了模型的可行性和有效性.同时还对这种模型中的粒子运动速度和系统效率进行了研究,给出了一些数值模拟结果.In this paper we proposed the tiling ratchet double feet moving model on the fact that actin＇s feet walk by turns. By numerical simulation, we showed that the model which we proposed here could describe this moving mechanism clearly, so it indicates the feasibility and validity of our model. In the meantime we also considered the speed of motor particle and system efficiency, and get some numerical results by simulation.
