鲨鱼皮泳衣是人们根据其外形特征起的绰号,其实它有着更加响亮的名字:快皮,它的核心技术在于模仿鲨鱼的皮肤.生物学家发现,鲨鱼皮肤表面粗糙的V形皱褶可以大大减少水流的摩擦力,使身体周围的水流更高效地流过,鲨鱼得以快速游 动.快皮的超伸展纤维表面便是完全仿造鲨鱼皮肤表面制成的.此外,这款泳衣还充分融合了仿生学原理:在接缝处模仿人类的肌腱,为运动员向后划水时提供动 力;在布料上模仿人类的皮肤,富有弹性.实验表明,快皮的纤维可以减少3% 水的阻力,这在1%秒就能决定胜负的游泳比赛中有着非凡意义.1999年10月,国际泳联正式允许运动员穿快皮参赛.
而关于穿什么样的泳衣游得更快,人们已探索了许多年.泳者在水中遇到的阻力,与水的密度、泳者的正面面积、摩擦系数及泳者速度的平方成正比,因此减少正面面积和摩擦系数是设计低阻力泳衣的关键.
英文:::The shark dried shark skin swim suit is the people according to the nickname which its contour characteristic gets up,actually it has a more resounding name:The quick skin,its core technologies lies in the imitation shark's skin.The biologist discovered that the shark skin surface roughness V shape folds may reduce fluent greatly the friction force,causes around body's current of water to wind through highly effective,the shark can hover fast.The quick skin's ultra extension textile fiber surface is copies the shark skin surface to make completely.In addition,this model of swim suit also fully fused the bionics principle:Imitates humanity's tendon in the connecting point,delimits when backward the water for the athlete provides the power; Imitates humanity's skin on the cotton material,high resilience.The experiment indicated that the quick skin's textile fiber may reduce 3% water the resistance,this in 1% seconds can decide that the victory and defeat in the swim meet has the extraordinary significance.in October,1999,Guojiyonglian allowed the athlete to put on the quick skin participation officially.what swim suit but does about put on to tour quickly,the people have explored for many years.The swimming the resistance which meets in the water,with water density,swimming frontal face area,friction coefficient and the swimming speed's square is proportional,therefore reduces the frontal face area and the friction coefficient designs the low resistance swim suit's key.
