阿尔卡拉斯在2022年美网夺冠，成为最年轻的世界第一。文章使用文献资料法、录像观察法、数理统计法、逻辑分析法对阿尔卡拉斯在美网夺冠的七轮比赛进行观察记录分析，得出其在发球、接发球、相持阶段、截击的技术特征，丰富网球基础理论，为网球爱好者、运动员、教练员提供训练和比赛的参考。结果显示：

1、发球上，阿尔卡拉斯发球稳定性很高，一区发球内外角使用率相当，内角略多于外角，二区发球外角多于内角；第二发球的得分率明显低于第一发球，发球质量与世界顶尖发球选手相比仍存在弱势。

2、接发球上，阿尔卡拉斯属于进攻型接发球，站位靠前，主要使用抽球接发，路线上多选择右路，进攻对手反手弱侧，成功率与得分率均较高。

3、相持阶段主要使用正反手抽球，正手多于反手，并能打出制胜分，放小球是他的得分利器。

4、截击成功率和得分率较高，但是在时机选择上有待提升。

建议继续提升发球能力，相持阶段中的反手能力，比赛中结合对手和比赛进程，擅于转变战术思想，选择合理的上网时机。

Alcaraz became the youngest world number one when he won the 2022 US Open. The article uses literature method, video observation method, mathematical statistics method and logical analysis method to observe and record the seven rounds of matches in which Alcaraz won the US Open to analyze his technical characteristics in serving, receiving, holding phase and interception to enrich the basic tennis theory and provide reference for tennis fans, players and coaches in training and competition. The results show that: 

1. On the serve, Alcaraz has high serve stability, the use rate of the inner and outer corners of the first serve is equal, slightly more than the outer corners, and the outer corners of the second serve are more than the inner corners; the score rate of the second serve is obviously lower than the first serve, and the quality of the serve is still weak compared with the world's top serve players. 

2. On the receiving serve, Alcaraz belongs to the offensive type of receiving serve, standing forward, mainly using the draw to receive the serve. He mainly uses the right side to attack the weak side of opponent's backhand, with high success rate and score rate.

 3.Mainly uses forehand and backhand pumping, more forehand than backhand, and can hit the winning point, putting small ball is his scoring weapon.

 4.The success rate and score rate of interception is high, but the timing needs to be improved.

 It is recommended to continue to improve serving ability, backhand ability in the phase of holding, combine with opponent and match progress during the match, be good at changing tactical ideas and choose reasonable timing of internet access.
