The second mechanism, "Pull," also limits WIP by making the production velocity of the upstream process dependent on the downstream consumption velocity.
第二个机制——“拉动式”——通过依据下游消耗速度来确定上游工序的生产速度，这种机制也限制了在制品的数量。
The bigger the downstream water level, the outstanding of variation degree of axial velocity along radius distribution when upstream water level is same.
下游水位越高，变化相同的上游水位时，轴向流速沿径向分布的变化程度越大。
The computed characteristic scales of the upstream vortex show distinguished three-dimensionality and vary with the velocity ratio and the water depth.
计算得到了上游壁面涡的特征尺度，结果表明上游壁面涡具有高度的三维性，其特征尺度依赖于流速比和环境水深。
