网球技术中发球是惟一不受对方牵制、完全自主的一项技术,按理说应是最易掌握的,然而事实却并非如此,原因有三:其一,发球动作与其他击球动作相比更为复杂;其二,规则对发球的限制较多,站在端线后使球越过0.914米高(网中心)的网且必须落在斜对面长6.40米、宽4.115米窄小的场区内,对于许多人(特别是个子矮小的)来说,的确不是件容易事;其三,对发球练习缺少足够的重视(职业选手除外)。下面来详细谈谈发球技术细节和经常失误的原因及纠正方法。 Serve in tennis is the only technique that is not subject to control by the other party and is completely autonomous.

Here to talk about the details of the service and frequent mistakes in the causes and corrective measures.
