To avoid the inaccuracy caused by this potential flow assumption, propeller designers have introduced the notion of the effective wake.

为了避免由于势流假设引起的不准确性，螺旋桨设计者引入了实效伴流的概念。

For orifice compensated aerostatic bearings, entrance effect leads differences between actual pressure distributions and traditional laminar flow assumption in gas film of the bearings.

小孔节流空气静压轴承中，由于进口效应现象的存在导致轴承气膜内实际压力分布不再符合传统的层流假设。
