Sometimes temporal fluctuation may take place inthe local velocity. 有时，在局部速度中可能出现瞬时脉动。
Such grids effectively smooth out the velocity fluctuation above the dense bed. 栅格在密相床层上有效地使速度波动平缓起来。
Comparison of velocity fluctuation distribution between clear and sediment laden flows 清水和含沙水流脉动强度分布比较
The socalled velocity of light invariable is the light fluctuation speed is invariable. 所谓光速不变是光的波动速度不变。
A series of formulas are presented in this paper about the mean velocity profile, the intensity of velocity fluctuation and energy spectrum. 纵、横向脉动流速强度分布和能谱密度计算式。
