李娜对决斯齐亚沃尼的法网决赛正在进行中,在第一盘中,李娜打出了一个Ace 球,保住了自己的发球局,也保住了领先的局势,成功拿下了第一盘。那么什么是Ace 球呢?

根据维基百科的解释:

In tennis, an ace is a legal serve that is not returned winning the point.
网球比赛中,Ace是一次有效发球,让对方无法回球从而直接得分。

In professional tennis, aces are generally seen on a player's first serve, where the server can strike the ball with maximum force and take more chances with ball placement (usually in the far corners of the service box).
在职业网球赛中,ace球通常出现在选手的一发,因为选手在一发可以用上最大的力气,在球的落点方面也能冒更大的风险(通常都是打在球场的远角)。

The most common placement of an ace is a hard flat serve to either the middle or the corner of the service box, or a spin serve out wide such as a slice serve to the deuce court for right-handed servers, or a kick serve, also known as a topspin serve, to the ad court for right-handed servers.
ace球最常见的打法是落在发球区的中线或者是角落,或者是旋转球比如切发球发到右手发球球员的右半边,或者是上旋发球,发到右手球员的左半边。

另外,高尔夫的一杆进洞、棒球队里的王牌投手,也都叫做ace哦!
