【摘要】 对体育场馆内风的成因进行了分析,认为乒乓球比赛时场馆内不可能做到绝对无风。就不同风力对乒乓球飞行轨迹的影响进行了定性分析,认为在球速相对较慢(V风≥1 m.s-1,V球≤5 m.s-1)时,不论是在顺风还是逆风状况,乒乓球的运行轨迹及其落点都会受到风力的影响,因此乒乓球比赛时必须重视赛场内的风速检测,对能引起赛场内风速的因素加以控制。更多还原

【Abstract】 After analyzing the formation of wind in stadium a conclusion is drawn that no wind is impossible in stadiums when a competition is on.Qualitative analysis of the impact of wind power on the pingpang ball’s flying trajectory has been carried out.The pingpang ball’s flying trajectory will be impacted when its speed is relatively smaller than that of the wind in spite of the wind’s direction.It is suggested that attentions should be paid on the check of wind speed in stadiums and some measures should be adopted to control the factors of wind speed.更多还原
