A theory is given for the swimming velocity of a flagellated bacterium and its variation with the viscosity of the surrounding fluid. The theory is shown to agree fairly well with the experimental observations of Schneider and Doetsch on Pseudomonas aeruginosa for viscosities greater than 2 centipoise. However, it fails to account for the decrease of velocity observed when the viscosity decreases from 2 to 1.1 centipoise.
给出了一种关于鞭毛细菌游动速度及其随周围流体粘度变化的理论。结果表明，对于粘度大于2厘泊的情况，该理论与施奈德和多伊奇对铜绿假单胞菌的实验观察结果相当吻合。然而，当粘度从2厘泊降至1.1厘泊时，该理论无法解释所观察到的速度下降现象。
