...况下，压力随时间的改变使得微扩散器内流向 (streamwise)的流速在达可能最大值之前即受到逆压 力梯度(adverse pressure gradient)的影响而减速。当频 率越高，流向的可达最高流速越低，使得净流率随之 降低。

The results indicate that passive control technique can reduce peak Mach number on the surface of the airfoil and reduce the adverse pressure gradient, shock is also weakened.
结果表明，被动控制使得沿模型表面的马赫数峰值及过压力梯度明显减小，激波减弱。
It is shown that the "damping" effect mainly exists in the zone of 0.5d from the impingement wall, and there are positive as well as adverse pressure gradient in the radial direction.
表明壁面的“阻尼”影响主要集中在近壁面0 . 5 D以内，在径向上流动既有顺压梯度，又有逆压梯度。
In zero pressure gradient flow, this local momentum loss is Minost an additive constant quantity. On the other hand, adverse pressure gradient results in amplification of this momentum loss.
在零压力梯度下，这个局部的动量损失几乎是一个附加的常量，而逆压梯度则会扩大这种动量损失。
