我们观察到纤毛虫草履虫如何试图从太窄而无法转弯的长毛细血管的死端撤退。经过多次短期向后游泳（SBS）的试验和错误事件，这是自由游泳中遇到障碍物时表现出的传统回避行为，长期向后游泳（LBS）持续时间长5到10倍。LBS可能对从毛细血管空间完全撤出有有益的影响，尽管在我们的实验中，由于毛细血管的长度，生物体不可能这样做。为了确定一个物理上可能的机制LBS，我们提出了模型方程的霍奇金-赫胥黎型，它描述了纤毛运动的控制膜电位。讨论了LBS产生的生理意义和物理机制。
We have observed how the ciliate Paramecium attempts to retreat from the dead-end of a long capillary that is too narrow for turning. After many trial-and-error episodes of short-term backward swimming (SBS), which is the conventional avoidance behavior exhibited in free swimming when an obstacle is faced, long-term backward swimming (LBS) that lasted five to ten times longer was developed. LBS may have a beneficial effect for complete withdrawal from the capillary space, although in our experiment it was impossible for the organism to do so due to the capillary length. In order to identify a physically possible mechanism for LBS, we propose model equations for the membrane potential of Hodgkin–Huxley type, which describe the control of ciliary movement. The physiological implications and physical mechanism of the development of LBS are discussed.
