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。

The experimental results indicated that these metal oxide catalysts had better catalytic activities to the methylene chloride gas at low concentration, and the catalytic activities increased with the increase of temperature,but decreased with the increase of inlet gas concentration. The CrO3/potsherd catalytic activity was better than V2O5/potsherd, and the CrO3/potsherd catalyst displayed higher activity at the relative low temperature. When the reaction temperature was 320 ℃, the conversion rate could reach 99%, and the result of 100h catalyst stability experiment show that the catalytic activities have good stability.

The results manifest that the concentration of glycocholic acid has satisfactory linear correlation whith peak area, regression equation: Y= 39579X + 57823,R2=0.9984;The lowest detected concentration is 0.02μg/mL with S/N=3 ; Average recovery rate is 98.49%; RSD为0.52%～2.00%in day, RSD为0.74%～4.98%between days;The average recovery rate is 99.35%, RSD is 2.24% in the first team, and it is 100.87%, RSD is 4.73% in the second team at the stability test. When the concentration of glycocholic acid was detected in the liver, kidney and brain tissue, corresponding tissue concentration was calculated by preparing the standard curve with the glycocholic acid standard preparation in vitro, but the result can only reflect the relative chang law of the concentration of glycocholic acid in tissue but not in real tissue. The result of tissue stability experiment is consistent with that of the serum experiment.
