摘要：网球运动制胜的机制在于发球的直接得分能力和接发球战术体系的得分实力高于对手。很多高水平选手的发球技术已经达到一定程度，但在比赛中还会出现由于紧张造成发球质量低下被对方进攻或双发失误而丢掉关键分直至破掉发局的现象。只有将优秀的发球技术、稳定的心理素质和成熟的发球局战术融合一体才能造就良好的发球局体系。本研究采用网球发球时速与成功率作为研究内容，以江苏省男子网球队为研究对象，旨在通过训练提高网球运动员发球成功率和击中率，使其发球时速更具有威胁性；探讨不同难度的发球时速对运动成绩的影响，为网球的日常训练献计献策。

从系统论的角度出发，我们分析可知，网球发球应包括四个方面的内容：技术层、战术层、心理层和体能层。技术、战术、心理和体能这些层面之间是互相联系、互相依存、互相制约、不可分割的整体。技术、体能是战术的物质基础，心理是战术的思想保证。比赛中技术、体能、心理总是在具体的战术配合，在战术行动中表现出来，并及时充分发挥和良好运用。但是，先进的战术可以反过来积极地促进技术、心理、体能的提高和发展。只有将这些因素看成一个相互联系的整体，并把它们彼此协调起来，使其最优化，才能获得最佳的发球效果。
