论文摘要
我们回顾有关复杂液体游泳的文献。通过将游泳者的长度和时间尺度与附近的障碍物进行比较，从刚性或软限制边界到分子延伸到分子，这些分类是通过比较游泳者的长度和时间尺度来提出的。分类中的三个维度是游泳者的浓度，它结合了纯粹由游泳生物的集体运动产生的液体。对于我们确定的八个系统类中的每一个，我们提供了背景并描述现代研究结果。尽管有些班级数十年来一直关注着很多关注，但另一些班级仍然是未知的水域，仍在等待探索。
We review the literature on swimming in complex fluids. A classification is proposed by comparing the length and time scales of a swimmer with those of nearby obstacles, interpreted broadly, extending from rigid or soft confining boundaries to molecules which confer the bulk fluid with complex stresses. A third dimension in the classification is the concentration of swimmers, which incorporates fluids whose complexity arises purely by the collective motion of swimming organisms. For each of the eight system classes which we identify we provide a background and describe modern research findings. While some classes have seen a great deal of attention for decades, others remain uncharted waters still open and awaiting exploration.
