摘 要:为了深入认识新型无缝塑料乒乓球的基本特征,测试其对击球速度和旋转的影响。采用了调查访问法、实验法和数理统计法等方法,对新型无缝塑料乒乓球与传统赛璐珞乒乓球进行实验比较。主要从无缝塑料乒乓球的弹跳、落点准确性、击球速度和旋转等方面进行了实验与分析。研究结果表明:无缝塑料乒乓球的硬度和弹跳高度均略高于赛璐珞乒乓球;无缝塑料乒乓球的弹跳落点和飞行弧线的稳定性和准确性优于赛璐珞乒乓球;无缝塑料乒乓球击球的平动速度比赛璐珞乒乓球减少约2%,旋转降低约5%;用无缝塑料乒乓球球和粘性套胶拉弧圈球的旋转略强于涩性套胶拉球的旋转。本研究为未来进一步适应新球的技战术训练和发展提供一定的理论依据和参考。In order to have a deep understanding of the basic feature of seamless plastic table tennis ball and discover its effects on the ball speed and ball spin,using the methods of interview survey,experiment and statistic,etc,this paper compared the new seamless plastic table tennis ball with traditional celluloid table tennis ball,focused on the ball bounce,landing accuracy,ball speed and spin speed. Results: The hardness and bounce height of seamless plastic table tennis ball are slightly higher than those of celluloid table tennis ball,the bounce landing points' and flying arc's stability and accuracy of the seamless plastic ball are superior. Speed of seamless plastic table tennis ball is 2% less than that of celluloid table tennis ball and the spin speed of seamless plastic table tennis ball is 5% less. The spin of pulling the loop with seamless plastic table tennis ball and sticky glue is stronger than that of pulling with astringent glue. This study provides theoretical reference for developing techniques and tactics to deeply adapt to new ball.
