从适当的线性化Navier-Stokes方程计算了在模型脂双层膜中进行匀速平移和旋转运动的圆柱的平移和旋转阻力系数。该计算作为膜结合颗粒的横向和旋转扩散的模型，并且可以用于从测量的扩散系数推断膜的“微粘度”。阻力系数的准确获得使用对偶积分方程技术。阐明了Saffman（1976）所得到的一个早期渐近解的有效区域。
The translational and rotational drag coefficients for a cylinder undergoing uniform translational and rotational motion in a model lipid bilayer membrane is calculated from the appropriate linearized Navier–Stokes equations. The calculation serves as a model for the lateral and rotational diffusion of membrane-bound particles and can be used to infer the ‘microviscosity’ of the membrane from the measured diffusion coefficients. The drag coefficients are obtained exactly using dual integral equation techniques. The region of validity of an earlier asymptotic solution obtained by Saffman (1976) is elucidated.
