Abstract: This paper presents a 2D impact model,and calculates the distribution of angular speed of lift-off and particles in Aeolian saltation by statistics through thinking about the effect of boundary condition.The result well shows agreement with the experimental result,which affirms the existence and the distribution of the angular speed of lift-off sand particles in theory

Key words: lift-off sand particle, spin, probability distribution
