摘　　要：运用刚体转动定律及流体伯努利方程,建立了排球单脚跳发弧旋球的力学模型,进而对其进行运动生物力学分析,并提出了排球单脚跳发弧旋球技术,结果表明,采用该项技术发球增加了对方接发球的难度,从而提高了发球的破攻率和得分率.Using rigid body rotation law and Bernoulli＇s equation of the fluid, set up the mechanics model of the volleyball one-leg take-off spin service technology, then adopts on Sports Biomechanics to analyzes it and propounds the volleyball one-leg take-off spin service technology. The results indicate that the technology greatly increases the difficulty of the receiver, and thus enhances broken attack rate and score points rate of serve.
