Abstract
Brownian motion (diffusion) of particles in membranes occurs in a highly anisotropic environment. For such particles a translational mobility (independent of velocity) can be defined if the viscosity of the liquid embedding the membrane is taken into account. The results of a model calculation are presented. They suggest that for a realistic situation translational diffusion should be about four times faster in relation to rotational diffusion than in the isotropic case.
摘要
膜中粒子的布朗运动（扩散）发生在高度各向异性的环境中。对于此类粒子，如果考虑嵌入膜的液体的粘度，就可以定义一个平动迁移率（与速度无关）。本文给出了模型计算的结果。结果表明，在实际情况下，平动扩散相对于转动扩散的速度应该比在各向同性情况下快约四倍。
