在本文中，尝试通过覆盖微生物众多纤毛末端的“信封”概念来模拟纤毛推进的动力学。这种近似可以在纤毛靠近在一起的情况下进行，就像在辛异时波的情况下发生的那样（即，波沿与有效拍动相同的方向传播）。为简单起见，选择了球形模型，随后的分析是对 Lighthill (1952) 关于近球形生物体蠕动运动的论文的修正。获得与推动惰性生物体所做的功相比的速度和效率，并与纤毛生物体的速度和效率进行比较。
In this paper, an attempt has been made to model the dynamics of ciliary propulsion through the concept of an ‘envelope’ covering the ends of the numerous cilia of the microscopic organism. This approximation may be made in the case when the cilia are close together, as can occur in the case of the symplectic metachronal wave (i.e. the wave travels in the same direction as the effective beat). For simplicity, a spherical model has been chosen, and the analysis which follows is a correction to Lighthill's (1952) paper on squirming motions of a nearly spherical organism. The velocity and efficiency compared to the work done in pushing an inert organism are obtained, and compared to that of a ciliated organism.
