摘　　要： 动作技术生物力学原理的建立过程,是一个复杂的创造性思维与实践过程。以2004年雅典奥运会乒乓球比赛中,柳承敏的发球为背景素材,结合运动生物力学与运动解剖学的相关理论,揭示"抖动式"发球的动作技术原理。依据发球动作的任务与性质,将"抖动式"发球技术分为抛球引拍阶段、挥拍加速制动阶段、挥拍鞭打阶段、挥拍轨迹拐点提肩阶段。以加速制动点、鞭打点、挥拍轨迹拐点为动作技术特征画面,分析挥拍加速制动阶段、挥拍鞭打阶段以及挥拍轨迹拐点基本力学特征与动作质量。最后,阐述了"抖动式"发球对提升发球爆发力与增强发球迷惑性的动作技术的基本规律。 The process of establishing a biomechanical principle for the techniques of moves is one of complex thinking and practice. This study began from a look at Ryu Seung-min＇s serves at the 2004 Athens Olympic Games, and in combination with related theories in sport biomechanics and sport anatomy, tried to uncover the technical principle for ＂dithering＂ serves. In accordance with the goal and nature of a serve ,we broke ＂dithering＂ serving technology down into four stages： tossing and tak- ing back, accelerating and braking, swinging and whip- ping, and shoulder lifting at the inflection point. We chose images at accelerating and breaking, whipping and inflec- tion points and analyzed the basic mechanical traits and qualities of the moves in these phases. Finally, the study interpreted the basic pattern of the moves in which ＂dith- ering＂ serves increase the power and the trickiness of ser- ving.
