players.Therefore,this dissertation chooses these two athletes as research objects and adopts the methods of literature review,video statistics,mathematical statistics and logical analysis to count the 11 matches that all the two athletes met in 2017-2018.The analysis is based on the separate statistical results between Dai Ziying and Chen Yufei in the view of technical and tactcal characteristics statistics of serving,return of service,the third shot,the second last shot and the last shot.By comparison and analysis of the data to analyze correlation between technical and tactical characteristic in serving stage and the attack and defense phase,conclusions are drawn as following:1.In the 2017-2018 World Badminton Championships,the win rate for Dai Ziying's was 86.99%,and 67.77%for Chen Yufei,both showed the increasing trends.2.In terms of serving:in the competitions between Dai Ziying and Chen Yufei,both athletes mainly chose to long and high service with

important role.With flexible pace,fast and accurate movement,the high attacking point can be achieved to take the initiative.Outlook:By analyzing the association rules of technic and tactic in competitive women's singles of badminton.It is hoped to I can learn the latest badminton singles skills and tactics to strengthen my theoretical knowledge and to improve my badminton skills and tactics.On the other hand,it also provides a certain theoretical basis for the regular training of the masses,and also offers a valuable reference for the normal training,hoping to contribute to the badminton education.
