旋转球与非旋转球运动的力学原理

The Principles of Mechanics for Spin Service and Non-spin Service

从足球、排球的击球方式和流体动力性能出发,建立力学模型,讨论了旋转球与非旋转球运动的力学原理,得到了弧线球的运动规律及其横向飘移的定量结果。

Following the ways of playing football and playing volleyball as well as hydrodynamic perfermance,the paper constructs mechanical models and discusses the principles of mechanics for spin service and nonspin service.The movement law of banana shot has been discovered and the quantitative result of its lateral fluttering has also been obtained in this research.
