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。

Yahoo can point out this obvious question: Yahoo does not have time reappear any deviation, google is in eye covetously and developing with Internet speed; Because this is abstracted,Yahoo is met and be immersed in had broken down long.

雅虎可以指出这个明显的问题：雅虎没有时间再出现任何偏差了，Google正在虎视眈眈并且以互联网速度在发展；雅虎会因此分心和陷入瘫痪过长时间。

The body's waist was pressed by a kind of continued and discontinued press for long time, the pubis abrasion did not fit the age, so the body was estimated she was a quean (then the work was not legalized in law, named demimondaine),she had been worked less than 6 .years.

Ginkgo biloba tree is not the result soon, but after a very long time; not soon grow taller, and some grow only a few centimeters in the last few decades, we can imagine, now tall and strong of Ginkgo tree to go through many years of ups and downs, and now they are known as the vegetable kingdom before the "giant panda","living fossil" and therefore we have to protect them.

银杏树不是很快就能结果的，而是经过很长时间；也不是很快长高的，有的二三十年也不过长出几厘米，可想而知，现在又高又壮的银杏树要经过多少年的风风雨雨，到现在人们才把它们称为植物界的"大熊猫"、"活化石"所以我们要保护它们。

Catarium that is naturally decomposed outdoors has an inhibitive effect on cabbage seed germination. While the inhibition effect increases with increase in extract concentration, it, however, decreases with decomposition time. With regards to the length of cabbage root, 0.1 g·mL-l aquatic extract of E. catarium inhibits root growth at every decomposition stage. With the exception of undecomposed E. catarium , other concentration extracts during decomposition enhances root growth. Aquatic extract from E. catarium also enhances cabbage stem growth.

滤纸培养皿试验结果表明：假臭草植株提取液对小白菜种子发芽的抑制作用随浓度增大而增大，且随植株分解时间的延长而逐渐减弱；就幼苗根长而言，不同分解时期0.1 g·mL-l的假臭草提取液对根长均表现为抑制作用，除未分解的假臭草以外，其他时期其他浓度的假臭草提取液对根系生长均有促进作用；假臭草提取液对小白菜茎长总体表现为促进作用。

But my original point, and it sure took long enough to get to, was that not one person on that entire plane, including the stewardesses, said one word to me.
