打乒乓球为什么要吹一下

吹球的好处

打乒乓球时，我们常常会看到选手在发球前吹球，其实这一动作并非无意义的举动，而是有以下好处：

  1. 消除球面污渍：乒乓球经常在地面滚动，球面容易沾染灰尘和污渍，吹球可以将球面清洁干净。
  2. 增加摩擦力：吹球后球面会变得湿润，增加了与球拍的摩擦力，有助于更好地控制球的旋转和速度。
  3. 稳定球质：吹球可以将球内的空气均匀分布，确保球的弹性和形状符合规定。

吹球的正确方法

吹球虽然看似简单，但却有一定的技巧，以下是吹球的正确方法：

  1. 将球放在手掌心，用另一只手托住球。
  2. 用嘴唇紧贴球面，轻轻吹气，让球面变得湿润。
  3. 用手轻轻摩擦球面，使其变得光滑。
  4. 将球放在手掌心，检查球的弹性和形状是否符合规定。

网下过球的是谁

在打乒乓球时，如果球打到网下后弹起，需要对方接球，这时候通常会说“网下过球的是谁”，到底是谁过了网下球呢？

  1. 如果球在落地前碰到对方的拍子，那么过网下球的人是对方。
  2. 如果球在落地前没有碰到对方的拍子，那么过网下球的人是打出这个球的人。
