有关乒乓球旋转的研究 ,国内乒乓界从感性上和理论上已作了一些定性分析 ,对于一些基本规律也作了许多阐述。但感性认识与实际情况有时不一定完全一致 ,不少问题还有待于通过定量研究来深入认识。然而 ,由于实时测量这种距近、快速的非金属物体运动目标 ,有一定特殊性和困难性 Regarding the study of table tennis rotation, the domestic ping-pong community has done some qualitative analysis from the perceptual and theoretical aspects, and also elaborated on some basic rules. However, perceptual knowledge and the actual situation may not always be exactly the same, many problems have yet to be in-depth understanding of quantitative research. However, due to the real-time measurement of this near-distance, fast moving objects of non-metallic objects, a certain particularity and difficulty
