| In this paper,Wang Chuqin and Lin Yunru and their mixed doubles partners were compared by the methods of literature,video observation,three-stage index evaluation,logical analysis and mathematical statistics.The data of 50 matches were collected and summarized.Then from each of their cricket technology,line,drop point and other aspects of the analysis,in order to find out the advantages and disadvantages of Wang Chuqin and his partner,so as to maximize the exploitation of his potential,and in the next cycle after the replacement of the old and new China table tennis shoulder greater responsibility.Based on this,the following conclusions are drawn:In singles: 1.On the whole,the advantages of Wang Chuqin and Lin Yunru are in the first four boards,that is,serve snatch and receive snatch,and the overall evaluation of both of them is better than serve snatch.The stalemate section is their common disadvantage,both of them are failed in the evaluation;2.Both Wang Chuqin and Lin Yunru are good at using the tactics of service rush,but Wang Chuqin is more efficient in scoring.The utilization rate of service control tactics of Wang Chuqin is higher than that of Lin Yunru,which can achieve the combination of attack and control,and the performance is stable.In the disadvantageous situation of service attack,Wang Chuqin’s coping performance is better than Lin Yunru’s,and her ability of resisting pressure is better.3.In the receiving and grabbing section,Wang Chuqin’s performance in the second and fourth boards is better than Lin Yunru’s,not only the direct scoring rate is higher,but also can achieve the combination of attack and control,and is more flexible in the choice and use of techniques and tactics;Lin Yunru in the second board a large number of backhand twist and pull service is characteristic,but in the choice of technology is too monotonous,lack of change,easy to be adapted by opponents;4.In the stalemate section,the performance of both of them is relatively poor.Relatively speaking,Wang Chuqin failed to convert more advantages into points in the active stalemate,and the ability to grasp the scoring opportunities is not strong;In the general stalemate of equal opponents,Wang Chuqin has a higher scoring rate and better stability;In the passive stalemate,Wang Chuqin has stronger anti-pressure ability than Lin Yunru.He is good at changing from passive to active and still can maintain a certain scoring rate.In mixed doubles: 1.On the whole,the overall scoring rate of Wang Chuqin/Sun Yingsha combination is higher,and the overall performance of the third Dan is better than that of Lin Yunru/Zheng Yijing combination;2.The common point of the two pairs is that the advantages are in the first four boards,that is,the first and second sections,but the disadvantages are in the same section;Male athletes play a dominant role in the game;2.Wang Chuqin/Sun Yingsha pair was evaluated as excellent and Lin Yunru/Zheng Yijing pair as good in the hair snatch section.The combination of Wang Chuqin and Sun Yingsha had a slightly lower usage rate in the service rush,but a higher scoring efficiency;Lin Yunru/Zheng Yijing had better performance in service control and service attack,mainly because Wang Chuqin and Sun Yingsha had lower quality of control technique in the third board;3.In the receiving and attacking section,both pairs were evaluated as excellent.Comparatively speaking,Lin Yunru is good at using backhand pull technique and high quality in serve receiving,Zheng Yijing women’s play has prominent masculine characteristics and strong desire to attack,while Wang Chuqin and Sun Yingsha lack flexibility in second and fourth board skills and tactical performance,failing to give full play to their own advantages.Therefore,the combination of Lin Yunru and Zheng Yijing performed better in the receiving and grabbing section.4.In the stalemate section,both pairs received a passing grade.Lin Yunru was dominant in the overall situation of stalemate,but his scoring rate was low,he failed to convert the dominant situation into points,and his ability to grasp opportunities was poor.However,Wang Chuqin/Sun Yingsha combination made more mistakes in the stalemate section and did not give full play to the superior techniques.In a word,the scoring rate of the two pairs in the stalemate section is roughly equal. |
