1·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。
2·The design of the bicycle reduces the effects of wind resistance and drag.
这种自行车的设计减少了风阻及曳力的影响。
—— 《柯林斯英汉双解大词典》
3·Drag is the force of air resistance pushing against a ball's motion and slowing it down, while lift is a force causing a ball to swerve off a straight path.
拉力是一种物体在空气中所受到的阻力，它能产生与球运行方向相反的作用力，减缓球的运行速度，而升力则是一种能使物体偏离直线运行轨迹的力。
4·The low-pressure area reduces wind resistance and hence the amount of drag, which means less energy is needed to maintain the same speed as the leader.
在低压力区，空气阻力减少，向后拉的力量减小，因此只需要消耗较少的能量就可维持与在前面的竞争对手相同的速度。
5·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。
6·The gas was slowed by a drag force similar to air resistance.
由于类似空气阻力的牵引作用，这些气体的（运行）速度减缓。
7·In aerodynamic terms, lift is a function of weight, thrust and drag (air resistance).
在空气动力学上，升力是重量，推力和阻力(空气阻力)的相关的函数。
8·During motion, the sphere may experience the fluid drag, as well as the resistance from the interation of the moving sphere and the channel bed.
在运动过程中，球体除受到周围流体阻力外，亦受到球体与底床间交互作用所形成的阻力。
9·The 12.6% of original fuel energy that makes it to the wheels must provide acceleration (5.8 %) and overcome aerodynamic drag (2.6%) and rolling resistance.
传到车轮的12.6%的能量，必需提供车辆加速(5.8%)、克服空气阻力(2.5%)和克服滚动阻力。
10·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。
