摘要
运用文献资料调研、观察、举证与类比推理等研究方法,结合生物流体动力学的例证解释人游泳时肢体与水环境的相互作用,发现由人肢体对水环境的作用所形成的涡流,具有动量转换的作用,它在高速旋转时所释放出的冲量是游泳推进力的重要组成部分。
By using the method of documentary investigation,observation,demonstration and analogism,combining with example of biohydromechanics to explain the interaction between limbs and surrounding water during swimming.The author finds out that the whirlpool formation of body limbs has the function of momentum conversion.It is the important component for swimming propulsion when momentum releasing during highspeed revolution.
