近年来，在羽坛中我国女子单打不再具有以前的优势。在国羽的黄金时代，我国女单的胜率可以达到百分之八十，而如今的胜率却只有百分之五十左右，已经失去以往的绝对优势。伦敦奥运会后我国羽毛球女单运动员出现了青黄不接的现象，而陈雨菲作为我国冲击东京奥运会的国羽一姐，总结并分析陈雨菲的技术特点，找出其优势和不足对其冲击奥运金牌是十分重要的。因此以我国优秀羽毛球女子单打选手陈雨菲为研究对象，运用文献资料法、录像观察法、对比分析法和数理统计法。对得失分、击球特征、技术使用情况，以及和对手技术的比较分析，得出以下结论：

1. 在得失分分布特征方面，陈雨菲在后场得分率最高，前场、中场失分率都高于其他选手。直接得分、受迫性失误和非受迫性失误与其他选手并没有显著性差异。

2. 陈雨菲直接得分最后一拍技术使用次数按大小排序依次是杀球>扑球>挡网>挑球>吊球>高远球>放网>勾对角>推球>抹球>抽球、拦网；最后一拍受迫性失误技术的排序依次有挡网>挑球>高远球>放网>杀球>吊球>拦网>抽球、勾对角>扑球>抹球、推球；非受迫失误次数按大小排序依次是杀球>挑球>放网>吊球>高远球>挡网>勾对角>扑球>抽球>拦网、抹球、推球。

3.陈雨菲对阵马琳时直接得分率最高，在对阵戴资颖时直接得分率最低，在对阵山口茜时非受迫性失误率最高，在对阵因达农时受迫性失误率最高。在场均得失分中，直接得分高于其他选手，受迫性失误和非受迫性失误均低于其他选手。

提出以下建议：

1. 在关键分时摆平心态，提高多拍相持能力，集中精力，主导比赛节奏，改变战术，可以用过渡球来调整我方心态和手感。加强击球时连贯控制和进攻的速度，提高预判能力，减少主动失误。

2. 在比赛中，掌握主动权，调动对手，提高场上移动能力，步伐的连贯性，击球一致性和隐蔽性。可以通过打四方球、打对手转身球、打重复落点调动对手，消耗对手体力。在巩固基本技术动作的同时，要提升高难度技术动作的运用，提高击球的精确性，有利于在比赛中变化球路，让对手措手不及，如网前勾对角、接杀斜线等。

3.提高直接得分能力，减少受迫性失误和非受迫性失误。减少非受迫性失误也就是相应的提高了直接得分。增加下压球的使用和提高下压球的质量，培养青少年比赛中“以攻为主”的意识，从而增加获胜率。

In recent years, my country's women's singles no longer have the previous advantages in badminton. In the golden age of Guoyu, the winning rate of women's singles in our country can reach 80%, but now the winning rate is about 50%, which has lost its absolute advantage in the past. After the London Olympics, the female singles badminton athletes in my country are in a state of failure. As the first sister of the national feathers of my country to hit the Tokyo Olympics, it is very important to summarize and analyze Chen Yufei's technical characteristics and find out his strengths and weaknesses. Taking my country's outstanding badminton women's singles player Chen Yufei as the research object, the method uses literature data method, video observation method, comparative analysis method and mathematical statistics method. The following conclusions are drawn on the points gained and lost, the characteristics of the shot, the use of technology, and the comparison with the opponent's technology:1. In terms of the distribution of scores, Chen Yufei directly scored slightly higher than other players in the world within ten beats, and forced and unforced errors were significantly higher than other players in the world after the eighteenth beat.

1. In terms of the distribution characteristics of scores and losses, Chen Yufei has the highest scoring rate in the backcourt, and both the frontcourt and midfield scoring rates are higher than other players. Direct scores, forced errors and unforced errors are not significantly different from other players.

2. The number of times Chen Yufei directly scored the last shot technique, in order of magnitude, is kill and kill the ball> pounce> block the net> pick the ball> drop the ball> high ball> put the net> hook diagonally> push the ball> wipe the ball> draw the ball 、 Blocking; the order of forced error techniques in the last shot is blocking the net> picking the ball> high ball> putting the net> smashing the ball> lobbing> blocking> dribbling 、 hook diagonally> throwing the ball> wiping the ball 、 pushing Ball; the number of unforced errors in order of magnitude is smash> pick the ball> put the net> drop the ball> high ball> block the net> hook diagonally> throw the ball> draw the ball> block the ball 、 put the ball 、 push the ball.

3. Chen Yufei had the highest direct scoring rate against Ma Lin, the lowest direct scoring rate against Dai Ziying, the highest unforced error rate against Akane Yamaguchi, and the highest forced error rate against Intanon. In the average points per game, direct scores are higher than other players, and forced and unforced errors are lower than other players.

Make the following suggestions:

1. Balance the mentality at key points, improve the ability to hold multiple shots, concentrate, dominate the rhythm of the game, change tactics, and adjust our mentality and hand feel with the transition ball.Enhance the speed of the attack and the control of the ball, improve the ability of prediction and reduce the active error.

2. In the match, master the initiative, mobilize the opponent, improve the ability to move on the court, the consistency of the pace, the consistency of the shot and concealment.Can play through the square ball, hit the opponent turn ball, hit the repeated drop point to mobilize the opponent, consume the opponent's physical strength.At the same time of consolidating the basic technical movements, we should enhance the use of difficult technical movements to improve the accuracy of hitting, which is conducive to changing the ball in the match and making the opponent unprepared, such as the diagonal hook in front of the net, the diagonal line of catching and killing, etc.

3. Improve direct scoring ability and reduce forced errors and unforced errors.Fewer unforced errors have resulted in a corresponding increase in direct scoring.Increase the use and quality of the down ball, and cultivate the awareness of "attacking as the main" in the competition, so as to increase the winning rate.
