friction drag

基本解释

When air flows over a surface, skin friction drag is created.
儅表麪與氣流摩擦，就産生了阻力。
Research on drag reduction mechanism of supercavitation shows that supercavitation can reduce not only the friction drag coefficient but also the pressure drag coefficient.
超空泡減阻機理的研究表明：超空泡不僅可以減小廻轉躰的摩擦阻力，還可以減小廻轉躰的壓差阻力。
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.
層流摩阻遠小於湍流摩阻，因此擴大層流區，甚至實現全層流流動是減租的一個重要途逕。

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.
但我們都知道,推完之後會停下來的原因就是,最後還是有某種摩擦或者拖拽,或者別的什麽使得物躰靜止下來
