优秀运动员

The result shows that the technical style of our athletes used is that stride length is shorter and stride frequency is larger,the buckjump time of our players is located at the floor level of the foul limit,the knee angel is unwind from touchdown on upright phase,in the sprint phase,the kneel angel is blurry from touchdown to upright phase,the uprightness displacement of body center and vertex are higher than the international athletes, this since stretching to leave a ground of opportune moment to be partial to early and making an effort action insufficiency with leg driving of the ankle joint relevantly, also with the leg put of front stretch is not enough active at the touchdown ground moment.

结果表明，我国运动员在后半程中，运用的是步长较短，步频较快的技术风格；腾空时间总体上处于犯规时限的下限，膝关节从着地瞬间直至垂直支撑面保持了可见的伸直状态，但在最后冲刺阶段，膝角出现了模糊伸直过程；身体重心垂直位移、头顶位置上下起伏均高于世界优秀运动员平均水平，这既与踝关节后蹬伸展离地时机偏早、用力动作不充分有关，也与着地瞬间摆动腿前摆后的前伸着地动作不够积极有关。

The authors performed 3D photographic measurement on the technical moves of ZHANG Wen-xiu as an excellent female hammer thrower in China to get relatively comprehensive body movement data by using two JVC3000 high-speed cameras, screened and analyzed the data by using SPSS software, and revealed the following findings: in terms of such technical parameters as spinning time, spinning track and spinning speed, there were some problems with this player, which restricted the enhancement of her performance, such as the double leg supporting time was shorter than the single leg supporting time; the angle of inclination of the track of various swirls (espe-cially the first swirl) was somewhat too big; the accelerating process was too short; too much attention was paid to acceleration at the single leg supporting stage; the spinning at the double leg supporting stage was too fast; the sus-tainable accelerating power was not high.

摘 要：采用两台JVC3000高速摄像机对中国女子链球优秀运动员张文秀的技术动作进行三维摄影测量，获得较为全面的人体运动学数据；运用SPSS软件对数据进行筛选和相关分析，发现该运动员在旋转时间、轨迹和速度等技术参数方面存在着一些制约成绩提高的问题，诸如双支撑时间短于单支撑时间、各圈(尤其第1圈)的轨迹倾角偏大、加速过程太短、单支撑阶段过于强调加速及双支撑阶段旋转过快、持续加速能力不强等。

The highest speed between hurdles of Liu Xiang surpass the average speed of the other 8 top 110m hurdlers' technique in world track and field championship in Paris France 2003 . The number of the clearance of hurdles in a high speed is as many as others.

刘翔的最高栏间速度超过了2003年法国巴黎世界田径锦标赛前8名的运动员平均最高分栏速度，保持高速度过栏的区间数也同其他优秀运动员相当，具备了战胜世界顶尖高手的实力。

We do not have remarkable difference in takeoff time with the world top athletes, but the relative longer cushion time and shorter time used in transformation and the pedal have reflected that we have excessively high approach useing rate, insufficiency speed reserve and bad leg strength.

我国运动员起跳时间与世界优秀运动员没有显著差异，但缓冲时间长，转化和蹬伸时间相对较短，时段的分配很不合理。

Tt suggests the high jumpers should improve the stability of approach steps in the foundation of improving the approach speed and adjust the final stride. Comparing with the foreign ones, the Chinese high jumpers have certain margins in the horizontal velocity of barycenter. Their power of supporting and stretching the leg are of a sort, so they should add to their quick power training of take-off leg.

建议运动员在应在助跑速度普遍提高的基础上，着重改善助跑节奏的练习，使之趋向合理；我国部分优秀运动员的助跑质心水平速度、水平速度与垂直速度转化方面还存有差距，应注意加强起跳腿快速力量的训练，特别是支撑力量的训练。

So the article focuses on the transition skill and how to affect the whole technique.Research method: Studying subject is Chinese excellent male shot-putter. Research methods are mathematics statistics and videotape analytic. We put two JVC GR-DVL9800 mini camcorders on the back of circle and the left side, they are made in Japan. And to take the whole match, then analysis the data, we found our players exist the shortcoming in skill by means of comparing with abroad athletes to be directed against individual character.

研究方法：以我国优秀男子铅球运动员为研究对象，采用录像解析和数理统计的方法，分别在投掷圈后侧和左侧各放一架日产JVC GR-DVL9800微型数字视频摄像机，完整地拍摄比赛全过程，而后对录像资料运用"爱捷"运动录像分析反馈系统进行数字化处理，并通过与国外优秀运动员的技术资料进行对比分析，针对我国运动员个人的技术特点，找出我国运动员技术方面存在的缺陷，并提出相应的解决措施，促使技术达到最佳化。

Result: Contrary to European and American people, I allele frequency of Han nationality is higher than that of D allele (P.05); II genotype frequency and DD genotype frequency are noticeably different from that of European and American people (P.01); No DD genotype appear in the excellent athletes, which is noticeably lower than that of control group and athlete group (P.05) and that of the excellent athletes reported in other countries; the frequency distribution of II genotype in Marathon is noticeably higher than that in 5km distance running(P.10); The changing of I allele Jl genotype IP ID genotype frequency indicates a stronger unary liner relation (r=0.9985) with the running distance lengthening(5ktru lOkrru Marathon).

结果显示：与欧美人群相反，汉族I等位基因频率高于D等位基因（P＜0.05）；汉族II型纯合子频率和DD型纯合子频率非常显著地区别于欧美人群（P＜0.01）；在优秀运动员中，DD型纯合子未出现一例，显著低于对照组和运动员（P＜0.05），也显著低于国外已报道的优秀运动员；马拉松项目II型频率分布显著高于5km（P＜0.10）；I等位基因、II基因型和ID基因型的频率变化伴随专项距离（5km、10km、马拉松）的增加呈现强相关的一元线性关系（r=0.9985）。

The result shows that the average somatolog ical values of the world elite synchronized swimmer s are 3.81 3.26 3.20 while the somatological values of the best swimmer s are 3.50 3.42 3.58.The somatotyp e mean value for the Chinese synchronized swimmer s is 3.85 2.50 3.75,which me somorphical value is obviously lower than the total average values and the best swimmer 's value.

结果表明，世界优秀花样游泳运动员的平均体型分值为 3.81 - 3.2 6 - 3.2 0 ，最优秀运动员体型的平均分值是 3.5 0 - 3.42 - 3.5 8，中国花样游泳运动员的平均体型分值为 3.85 - 2 。5 0 - 3.75 ，中因子分值明显低于总体均值和最优秀运动员值。

Meanwhile, in view of the main issues, put forward: 1 study and training development at the same time, raise the competitive edge of excellent athletes, of local personnel training should be based, the culture of reserve relents should base on the Fujian"s native athlete; 2 joint training with the college team Student athletes colleges and universities linked to the frontline players solve; 3 competitive conditions relaxed、order more Competition、give the champions 2-3 golds; 4 optimizing the training conditions; 5 improving the post training system of the province"s coaches.

针对出现的主要问题，提出了发展对策：1学习和训练同步发展，提高优秀运动员的竞争能力，人才培养应立足本土，引进为辅；2与高校联合培养队员，通过运动员在高校挂学籍等解决一线运动员出路；3竞赛规程条件放宽、多举行比赛、可给予冠军队2-3枚金牌；4优化训练条件；5完善全省教练员岗位培训制度。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
