body drag

基本解释

Female fat tends to be disproportionately distributed in the lower half of the body, giving a bit more lift to the legs which in turn reduces body drag.
女性的脂肪在身体的分别并不平均，在身体的下半部分更多一些，这使得她们的腿浮得更高，减少了身体的拖动。
The results shows that the vertical and thrust forces of the wings, which balances the weight and the body drag, are mainly contributed by the drag of the wings.
结果表明：蝴蝶主要用“阻力原理”作拍动飞行，即平衡身体重量的举力和克服身体阻力的推力均主要由翅膀的阻力提供。
Experiment investigation shows: The main body zero drag can be reduced by faovurable interference of jet flow. Then an optimuns afterbody configuration can be obtained.
实验研究表明，利用喷流的有益干扰，可使主弹体零阻显著下降，从而得到一种优化的后体外形。

Since the drag on a human body is approximately seven hundred and eighty times as great in water as in air, swimmers wearing the suits were able to post faster times.
