| 摘 要： | 你经常观看足球比赛的话，可以看到球绕过了“人墙”，眼看要偏离球门飞出，却又沿弧线拐过弯来直入球门，让守门员措手不及，眼睁睁地看着球进了大门。这就是颇为神奇的“香蕉球”。那么“香蕉球”是怎样踢出来的呢？本论文将对此进行研究。目的：怎样才能踢出“香蕉球”和“香蕉球”是如何形成的。分析方法：运用基础的物理知识——流体力学和动力学对球的运动和受力进行分析。结论：当人给球力的有个角度（0〈α〈90），就可以让球发生旋转，经过一定的位移后在风力的作用下球会呈弧线运动，而产生了“香蕉球”。在足球运动中，通过这样的球能让守门员防不胜防，达到进球的目的。

| Abstract: | Are you often watching the football game and seeing the curve ball around the wall directly scoring the goal. This is the wonderful curve ball. How to kick the curve ball？ This paper makes study on it. Through using the method of basic physical knowledge-hydromechanics and dynamics, the author makes analysis on ball movement. The result shows that when the ball is kicked at certain angle, the ball got circumrotated movement. During football match, the curve ball can hardly be defended by goalkeeper. |
