中文摘要：

chiral 活跃的粒子在 microchannel 导致的被动粒子的运输被在一个二维的模型系统使用 overdamped Langevin 动力学模拟调查。由于活跃粒子的 chirality 和 microchannel 的特殊结构，被动粒子的有效棘轮运输被完成。被动粒子的有效运输取决于 microchannel (d) 的宽度，密度() ，并且尖速度()chiral 活跃的粒子。在那里存在为 d 并且在为被动粒子的运输效率在哪个拿它的最大的价值的最佳的参数。这调查能帮助我们理解活跃运动的必要性让生活系统坚持说象材料那样的很多重要进程在内搬运房间和活动有机体的 foraging 动力学。

英文摘要：

Transport of passive particles induced by chiral-active particles in microchannel is investigated by using the overdamped Langevin dynamics simulation in a two-dimensional model system. Due to the chirality of active particles and special structure of microchannel, effective ratchet transport of passive particles is achieved. Effective transport of passive particles depends on the width of microchannel（d）, the density（ρ）, and the angular velocity（ω） of chiral-active particles.There exist optimal parameters for d and ω at which the transport efficiency for passive particles takes its maximal value.This investigation can help us understand the necessity of active motion for living systems to maintain a number of vital processes such as materials transport inside cells and the foraging dynamics of mobile organisms.
