1·But for the continuous jet which velocity gradient is not linear, it has not only one virtual origin.

但对于非线性速度分布的连续射流，存在的虚拟原点不是唯一的。

2·The effects of the velocity gradient and wall-proximity on the measuring errors are related to the flow direction.

近壁对总压测量影响不大。速度梯度和近壁对测量误差的影响还与来流方向有关。

3·The sound field of normal modes in the. shallow-water having negative velocity gradient and rough interface are calculated using such results.

5·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。

6·The results show that a large velocity gradient emerges in the intermeshing region of the screw reactors, which is helpful to mix materials sufficiently.
