By use of this model, it is demonstrated that the Karman constant is varied in vertical distance from near (0.4) in near bed region to below (0.4) in main flow region.

利用该流速分布模型，得到挟沙水流的卡门常数沿垂线是变化的结论，即从近底区的约0.4渐变到主流区的小于0.4。

When the bed load round the cylinder with water flow, a region of non sediment's moving will be formed in the bed layer near the cylinder.

试验发现推移质泥沙随水流绕过圆柱体时，将在圆柱周围的床面上形成一个无沙区。
