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 velocity gradient of the mixing mechanism is the essential reason of the inefficient zone.───搅拌装置工作时存在的速度梯度是低效区产生的根本原因；
3、effects of the velocity gradient and wall-proximity on the measuring errors are related to the flow direction.───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。

1、While the half angle increases, velocity gradient in a microdiffuser decreases and so does the average vorticity.
2、The ratio of the magnitude of an applied shear stress to the velocity gradient that it produces; that is, a measure of a noncrystalline material's resistance to permanent deformation.
3、The turbulence is being kept going by the working of this against the mean velocity gradient.
4、Thus the difficulties of discontinuous velocity gradient and the stress singularity at the exit point are avoided, and the expense of computation is reduced.
