标题： Stokesian swimmers and active particles

摘要： 在低雷诺数游泳的双线性理论框架下，研究了变形球体的稳态流动模式。 认为相互作用活性粒子理论的起点应基于此类计算，因为任何任意选择的稳态流动模式不一定是游泳运动的结果。 此外，强调通常情况下，搏动的相位在水动力相互作用中是相关的，因此必须谨慎使用净流动模式。 显示英文摘要

摘要： The net steady state flow pattern of a distorting sphere is studied in the framework of the bilinear theory of swimming at low Reynolds number. It is argued that the starting point of a theory of interacting active particles should be based on such a calculation, since any arbitrarily chosen steady state flow pattern is not necessarily the result of a swimming motion. Furthermore, it is stressed that as a rule the phase of stroke is relevant in hydrodynamic interactions, so that the net flow pattern must be used with caution.
