velocity gradient

基本解释

Velocity gradient collision is more propitious to agglomerate than Brown collision.
速度梯度碰撞与布朗碰撞相比较，前者更有促进碰撞凝聚。
The first, how to sort out data coming from experiments by the theory of boundary velocity gradient; Secondly, how to apply the data in practice.
在实践中应用该理论涉及到两个问题：一是如何将实验测得的数据整理成边界极限速度梯度，二是如何利用边界极限速度梯度反过来指导实践。
The results show: the mass throughout, take-up speed and intrinsic viscosity affect the velocity gradient greatly, showing that they influence the formation greatly;
结果表明：泵供量、卷绕速度、切片粘度对速度梯度影响较大，从而影响纺丝成形；
