resistance drag的意思|示意

In physics, drag refers to the resistance experienced by an object moving through a fluid medium (such as air).

从物理学的角度看，drag指物体在穿过某种流体媒介(如空气)时遭到的阻力，而zero drag则是描述物体不受任何阻力的理想形状。

Part of the ship resistance is viscous resistance, which divided into form drag and friction resistance.

船舶航行阻力的一部分为粘性阻力，其中又分为形状阻力和摩擦阻力。

Holding the body on the side produces no more or no less drag resistance than holding it prone in crawl or backstroke.

保持身体在一侧的姿势产生的拖曳阻力相对保持身体水平的姿势来说是一样的，不多也不少。

When the shape of a wing creates more lift from the air passing around it than it does drag (air resistance), an aircraft will fly.

当鱼鳍的形状通过流动的空气产生比其(空气)阻力更多的升力时，飞行物便能飞翔。

Working area for drag reduction agents (dra) is in turbulence area, and it can reduce resistance as well as increase transportation effectively.

减阻剂的作用区域在流体的湍流区，它能有效的降低流体阻力增加流量。

Dry Drag for true water resistance.

干拖动真正的耐水性。
