训练不够

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。

It is a start, but hardly adequate training for an absolute dictator.

这只是个开始，但是要成为一个十足的独裁者，这点训练是不够的。

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。

Through the analysis and investigation on the present teaching program of the representative 26 universities found at present aerobics major course of specialty of physical educationhave many insufficiency: target oretation is imperfect, neglect skill cultivatement; the curriculum content is irregular, insufficiently attention on the physique and the dancer training and the medical care and the movement damage; The development of functional exercises is current tendency, but has the certain difficulty, the main reason is the equipment is insufficient, generally the investment of aerobics major course is insufficient;Curriculum study is difference, the skill study is few, cannot satisfy the demand to cultivate specialist; The teaching appraisal system is not science, mainly take the end test as the major targets or quotas, pay more attention to technical inspection, neglect its synthesis influence to the students' physical and psychological quality, cann't utilize self-comment, the other comments, mutually comments.

通过对具有代表性的26所高校的现行教学大纲的资料分析、调查发现，目前体育育专业健美操课程存在的不足主要体现在：课程目标定位不完善，忽视技能培养；课程内容参差不齐，不够重视形体与舞姿训练、卫生保健与运动损伤知识；拓展功能健身操是当前的一大发展趋势，但是存在一定的困难，主要原因是场地器材不足，普遍存在着对健美操课程的投资力度不够的现象；课程的学时比例差异大，技能学时偏少，不能满足培养人才的需求；教学评价体系不够科学，主要以终结性考试为主要指标，忽视评价诊断特性和过程性，没有将自评、他评、互评综合运用。

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。

The most important thing may be how to put what we've learned into practice, lf you only learn the grammatic rules by heart and don' t do enough exercises, it is certain that you can't understand them perfectly.

最重要的是怎样把我们所学的东西用于实践。如果你只是背语法规则但训练得不够，当然你就不会完全理解这些语法规则，但是，如果你大量训练，或许你会深刻地理解这些语法规则，并且。

The effect of spare-time training of club is generally good,another 3 organizing forms are not satisfactory because of disadvantage of comptition system、insufficient funds、unguaranteed training time and unsteady coaching staff.

其中体育俱乐部的课余训练效益普遍较好。其它3种形式都因竞赛制度的弊端，经费不足、训练时间不能保证、教练员队伍不够稳定，而导致训练效益和成材率不尽人意。

However , our nation did a little effort in this field , especially in the daily drill of posse , so video games suitable for military is urgently needed .

然而我国在这方面的应用不够深入，尤其是警卫部队的日常训练，急需一款适合我军的电脑游戏训练系统。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
