摘　　要： 本文通过理论研究得到了质点沿旋转的圆筒筛外表面运动规律,讨论了质点在筛面运动的速度V_τ以及其他临界参数,如质点角速度开始超过筒面角速度时的角位移θ_(20)等,在实验室试验中用高速摄影定性验证了理论分析的结果,从而为研究筒筛的筛分机理和合理选取参数提供了理论基础。 In this paper through theoretical analysis the motion law followed by the materials moving on the outside surface of a cylinder screen (MOCS) was developed. The analysis formulated the motion of the particles on the cylinder surface and the critical parameters e. g. particle's velocity along the surface (Vr), angular displacement of the particle at the time when its angular seped begin to exceed the cylinder surface's(θ20).In laboratory experiment by means of high speed photography the result of theoretical analysis was verified qualitatively. Consequently it provides a theoretical fundament for the further study of separation mechanism of the 'MOCS'and rational determination of the pertaining parameters
