第1节和第2节概述了具有鞭毛的微生物和相关生物体的生物流体动力学方面，随后更详细地描述了（i）真核生物鞭毛的运动（原生动物和藻类），基于“弯曲”的繁殖沿着鞭毛的特征“9+2”结构，（ii）运动的细菌推动的“束”鞭毛细丝的结构完全不同，每一个都由其底部的“旋转马达”驱动。为了分析所有这些运动，有人认为，现在需要一个真正的“鞭毛流体动力学”。这应该取代“鞭毛动力学”（代表流体介质的原油阻力系数），迄今已被普遍使用，但其准确性是不够的现代微生物学家的要求。数学方法被应用于启动这样的鞭毛流体动力学的发展§ 3。最后，在第4节中，它的结论用非数学语言进行了总结。
Sections 1 and 2 give a general overview of biofluiddynamic aspects of microorganisms possessing flagella and of related organisms, followed by more detailed accounts of (i) motions in eukaryotic flagellates (protozoans and algae), based on the propagation of “bends” along flagella with the characteristic “9+2” structure, (ii) motions in bacteria propelled by “bundles” of flagellar filaments of quite different structure, each driven by a “rotary motor” at its base. For analyzing all these motions, it is argued that a true “flagellar hydrodynamics” is now needed. This should replace the “flagellar dynamics” (representing the fluid medium by crude resistance coefficients) which hitherto has been universally used, but whose accuracy is insufficient for the modern microbiologist’s requirements. Mathematical methods are applied to initiate the development of such a flagellar hydrodynamics in § 3. Finally, in § 4, its conclusions are summarized in nonmathematical language.
