1、but it increases the viscous forebody drag including the skin friction drag and shock wave drag.───但却增大了包含摩擦阻力和激波阻力的粘性前部阻力。
2、Improved Calibration Method of Skin Friction Drag Balance───一种改进的阻力天平仪校准方法
3、The underwater high-speed vehicle surfaces are enveloped by cavity entirely or mostly, which reduces skin friction drag and allows the vehicle to obtain high speed.───水下超高速航行体的全部或大部分表面被空泡包裹,使其阻力显著降低而达到高速航行的目的。
4、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。
