训练不够的

There is a small action range in archery.Simple methods and analysis is inadequate,so the author,on the basis of testing the archery athletes in national team with the Qualisisy infrared photoelectric testing system,Footscan sole pressure testing system,Noraxon myoelectricity remote testing system, etc,analyzes comprehensively the action technique of the athletes in national team from the posture,body motion characteristics,body posture equilibrium and stability,distribution of centre sole pressure, myoelectricity characteristics,etc,with the methods of relative software and data statistics.The conclusions and the suggestions are as follows:Conclusion:Firstly,the communality of posture angle,muscle strength,the activation order of main muscle during raising the bow, raising the bow and the timing of the raising could be used as the evaluation index of technique action in archery;Secondly,the length of the time needed in the different periods couldn\'t be used as technique evaluation index since it has no relation with the result.But the time of raising and pulling back the row is relatively fixed,and the time has a positive relation with the archery achievement of the national team in China.Thirdly,the central index of the sole pressure could be used as the reference criterion of selecting athletes and forecasting achievement.During playing archery,the interrelation between the central index of the sole pressure and the achievement is different individually and in different periods.Fourthly,there is low stability of the archery athletes in the front and back direction during the action, caused by the athletes\' posture disequilibrium of dorsal abdominal muscle and non-professional sport shoes..Fifthly,kinematics and electromyography shows that the people on archery in China haven\'t taken the raising and pulling back the row seriously.

射箭的肢体动作幅度小，简单的手段和分析不能满足其需要，笔者结合各种运动生物力学仪器优点及射箭项目的特性，选用Qualisisy红外光点测试系统、Footscan足底压力测试系统、Noraxon肌电遥测系统等对国家队射箭队运动员进行多方位的测试，运用相关软件及数理统计方法，对运动员的射箭动作技术，从射箭动作的姿态构架、肢体运动特点，身体姿态平衡稳定性、足底压力中心分布、肌电特性等进行全面分析，结论及建议如下：结论：第一，姿态角、肌肉用力激活程度、举弓阶段主要用力肌肉激活顺序、举弓、开弓时间等的一致性可作为射箭技术动作评价指标；第二，各动作阶段所用时间的长短不能作为技术评价指标，但举、开弓的时间相对较固定，开举弓时间比与中国国家队射箭成绩正弱相关达到显著性；第三，闭眼状态下足底压力中心单位面积轨迹长与144支箭最好成绩正相关达到显著性，可作为身体素质、选材及成绩预测的参考依据；实射时身体平衡的足底压力中心指标与成绩的相关程度具有个体性差异、阶段性差异；第四，射箭运动员实射时身体在前后方向上的稳定性较差，这与运动员的站立姿态、腹背肌力量的不匹配以及射箭没有专业运动鞋有关；第五，运动学及肌电学都表明中国射箭训练对举弓、开弓阶段的重视不够，背部肌肉用力特征不明显，撒放技术合理性不高。

Genetic Algorithm based methods can get rid of the problem of local optima, but they are not very effective to refine an existent good solution.

基于遗传算法的训练方法能够摆脱陷入局部最优的困扰，但遗传算法的局部搜索能力不够，从而影响网络的训练效果。

The person of this administrative levels is to just enter the recruit egg of travel child, the technology that they understand is not quite much, and train to be compared relatively at ordinary times little, not quite severe also to oneself requirement, self-ordained target, always cannot hundred finish.

这个层次的人是刚刚入行的新兵蛋子，他们了解的技术不够多，而且平时训练相对比较少，对自己的要求也不够严，自己制定的目标，总是不能百分百完成。

We believe the misuses and problems that we found generally were the problem of mistakes, carelessness, confusion, sloppiness, lack of training, lack of adequate guidance and lack of adequate oversight, he said.

Absrtact: The authors Investigated and analyzed present situation of reserves ladderlike of professional clubs of the China. The result shows that it will become main ways to cultivation reserve ladderlike of professional club in China because it is better than traditional training of sports system on quali fication of y oung player. And it has succeeded to train the basketball y oung players being excellent players. But there are s ome shortage that the club manager can' t attach importance to learn the culture for y oung players and coach need improve abilities of scienti fic training.

摘 要：通过对我国职业篮球俱乐部后备队伍现状的调查与分析，表明职业篮球俱乐部在培养后备人才的条件上，相对于传统的培养渠道而言占有优势，这将成为我国职业篮球运动后备人才培养和输送的主要途径；其后备队伍在为培养和输送优秀篮球运动员上已获成效；存在的不足是俱乐部对运动员的文化学习不够重视，教练员的科学化训练能力有待提高。

The current inland small class vocal education commonly depends on traditional omnifarious breathing and vocalizing training that usually based on the teacher 's subjective experience .

目前国内的声乐教学以小课为主，依赖于传统的，五花八门的，通常基于教师主观经验的呼吸发声训练，师生对于歌唱的机理和心理的系统了解不够。

Though industry names are starting to deal with the problem, the high staff turnover rate on the mainland means that luxury goods staff are often woefully undertrained and uneducated about the brand.

虽然产业知名品牌已经著手开始处理这个问题，大陆高人员的流动率意味著对该品牌的训练以及教育不够。

The results show:①the injury causes both physical and psychological block in the athlete, which will directly influence the injured athlete in future training, competition and recovery;②most of the athletes are lack of the knowledge about injury prevention and the means of psychological recovery;③some coaches attach little importance to preventing the athletes from injury.

研究结果显示：①跆拳道运动员发生运动损伤之后，将会产生巨大生理及心理的障碍，这些障碍将直接影响以后的训练、比赛和健康恢复；②目前大多数运动员自身十分缺乏预防损伤和损伤后应该及时采取的心理恢复方法、措施等方面的意识和知识；③部分教练员对运动员事先如何有效地预防运动损伤的重视不够，措施乏力。

Fred correct a wrong control in my steep turn as I didn't use enough power to pull back the column so my nose dropped rapidly when my angle of bank excess 30 degrees.

Fred在训练中指正了我的一处操纵上的问题。问题在于我在急速转弯的时候对操纵杆的操控力度不够，这样直接造成了在转弯角度大于30度之后，机头有明显下降的趋势，失去高度。
