On the Diffusivity of Small Particles

[摘要] It has been theoretically proved that the diffusivity of small particles depends on the size of particles. And it has been derived that the diffusivity constant becomes a constant which coinsides with the kinematic viscosity when the size is very small; on the other hand when the size is large, diffusivity constant becomes very small compared with the kinematic viscosity.
