| 摘 要： | 本文运用刚体转动定律及流体伯努利方程对排球发侧旋球的弧线飞行原理和侧旋速度对飞行轨迹以及着地点进行理论分析研究,结果表明击球点于球体重心右侧1/3处、击球挥臂出手方位面向球网方向右转30度,用中等力量击球实效性较高。

| Abstract: | The use of rigid rotation law and Bernoulli's equation of fluid on the volleyball side of the arc spin the ball flight and the principle of rotation speed on the side of the flight trajectory and the locations of theoretical analysis,results showed that the focus of hitting balls right at the point 1/3.Arm strike shots hit the net position for the direction of a right turn 30 degrees,with middle-effectiveness of the higher power hitter. |
