摘　　要：掌握网球落地反弹的规律并利用反弹规律合理采用击球方法 ,是网球运动员打好球的关键。采用摄像和多媒体技术以及力学分析 ,结果显示 :网球击球的入射角一般在 12°～ 30°之间 ,中等速度飞行的上旋球和平击球落地反弹后反弹角小于入射角 ,下旋球的反弹角大于入射角。网球的落地反弹形式有二种 ,一种是一般的反弹 ,球与地面没有滑动。另一种是球与地面有滑动的滑动反弹。滑动反弹的球 ,角度小、速度快更具攻击性。场地与球的摩擦系数越小 ,入射角越小 ,入射速度越快 。The key for tennis players to play tennis well is to master the laws of rebound after the placement of a tennis ball. By videoing and applying multimedia technique as well as mechanical analysis it was found that the incident angle of delivering the tennis ball is generally between 12° and 30°, the rebound angle after the rebound of the topspin ball flying at a moderate speed and the placement of the flat stroke is smaller than the incident angle. The rebound angle of the backspin is greater than the angle of incidence. There are two forms of rebound after the placement of a tennis ball. One is an ordinary rebound with no slide between the ball and the ground. The other is a rebound with a slide between the ball and the ground - the sliding rebound, in which the rebound angle is small, the speed of the ball is faster and the ball is more aggressive. The less the friction between the ground and the ball is, the smaller the incident angle is. The faster the incident speed is, the more easily the sliding rebound will be produced.
