摘要
运用计算机仿真技术 ,对不同初始条件下平击发球轨迹变化的规律进行分析。研究表明 ,击球点越高 ,发球成功率越大 ;发内角球比发外角球成功率大 ;在一定范围内 ,宁可降低击球点高度而使击球点靠近球网 ,可提高发球的成功率。给出以不同初速度和高度发球时球拍角度的参考值。
The trajectory variations of flat serve in tennis at different initial conditions were analyzed using computer simulation. It is found that the higher the flat point, the higher the successful rate; inner angle floating has more successful rate than outer angle floating; and successful rate of flat can be increased by lowing flat point and near the net. Reference values of the serving angles of the racket with different speed and height were provided.
