The rowers waited their oars half lifted out of the water like birds drying their wings .

船夫们等待着，他们的桨半举在 水面外，象是海鸟在晾干它们的 翅膀 似的。

Experiments of flow visualization and dynamic pressure measurement were carried out in a water channel and a wind tunnel respectively to research oscillations of the vortex breakdown location over delta wings .

在 水槽中和风洞中分别进行了流动显示和动态测压实验，目的是研究三角 翼前缘涡破裂点的脉动现象。

The water bird tucked its wings and dived into the water .

The static contact angle of water droplet on the surfaces of the wings was measured using an optical contact angle measuring system . Results show that the contact angle is in the range from 134.0 ° to 159.2 ° which indicates the surfaces of the wings are super-hydrophobic .

用视频光学接触角测量仪对 翅膀表面的静态接触角和滚动角进行测量得到：接触角为 134.0°~159.2°，表明翅膀表面具有较强的疏水性；
