friction drag

基本解释

When air flows over a surface, skin friction drag is created.
当表面与气流摩擦，就产生了阻力。
Research on drag reduction mechanism of supercavitation shows that supercavitation can reduce not only the friction drag coefficient but also the pressure drag coefficient.
超空泡减阻机理的研究表明：超空泡不仅可以减小回转体的摩擦阻力，还可以减小回转体的压差阻力。
Since laminar friction drag is much less than the turbulent one, one of the important measures for reducing it is to increase the laminar flow extent, and if possible, to realize a fully laminar flow.
层流摩阻远小于湍流摩阻，因此扩大层流区，甚至实现全层流流动是减租的一个重要途径。

But we all know that the reason things come to a halt when you push them is, there eventually is some friction or drag or something bringing them to rest.
但我们都知道,推完之后会停下来的原因就是,最后还是有某种摩擦或者拖拽,或者别的什么使得物体静止下来
