摘要: Wiener’s path integral theory is revisited, stressing that it holds only when the condition of local equilibrium fulfilled.The diffusion a particle in two and three-dimensional shear flow studied, showing for small time intervals diffuses freely, without being influenced by velocity gradient incident flow, while long exhibits dependent dispersion coefficient.
