| 摘 要： | 本文介绍了床面固体颗粒随水流绕过圆柱体，将在圆柱周围的床面上形成一个无粒子运动区的试验现象，根据动能定律，建立了圆柱直径，固体颗粒粒径和水流强度同无粒子区的定量关系，从该定量关系所作的理论分析结果同试验现象是完全一致的。

| Abstract: | This paper presents the experiment phenomena of particle at bottom in cylinder circulation flow.When bed load round the cylinder with water flow,a region there are no particle's moving will be formed in the bed layer near the cylinder.Based on the law of kinetic energy,the formula of the region no particle's movement is set up.The analysis results from the formula are agreed with the experiment phenomena. |
