Fluid Dynamics of Swimming 游泳的流体动力学翻译：crime222

Most people enjoy swimming, especially on a hot summer day. However, the level of swimming skill varies greatly between recreational and competitive swimmers. Even at the competitive level some swimmers are faster than others. The fastest swimmers use the fundamental (basic) principles of fluid dynamics the best. These same principles have been used by anyone who has ever treaded water (keeping your head above water by moving your arms and legs).

很多人都喜欢游泳，特别是在炎热的夏季。然而，这些游泳爱好者的水平则千差万别，不一而足。有的人只是用来娱乐，而有些人则用来参与比赛。即便是那些参加比赛的人中间，也有些人远比其他人有的快。而那些游得最快的人，他们一般都很好的遵循了流体力学的原理。但实际上这些原理每个人都在使用，只要他们会踩水（能够通过手臂和腿的运动将头部维持在水上）。
