本文研究了自推进颗粒在二维分离通道中的输运问题。通过施加交流力，颗粒将被分离的壁捕获。一个直流力产生的系统的不对称性，并诱导纵向定向输运。由于自推进力和联合外力之间的竞争，输送对自推进速度和颗粒半径敏感，因此可以根据这些特性分离颗粒。
Transport of self-propelled particles in a two-dimensional (2D) separate channel is investigated in the presence of the combined forces. By applying an ac force, the particles will be trapped by the separate walls. A dc force produces the asymmetry of the system and induces the longitudinal directed transport. Due to the competition between self-propulsion and the combined external forces, the transport is sensitive to the self-propelled speed and the particle radius, thus one can separate the particles based on these properties.
