铁饼

I am an amphora with motifs showing three pentathlon events: the long jump,javelin and discus.

我是一个瓶子，身上画有五项全能比赛中三个比赛项目的图案：跳远、标枪和铁饼。

Yes, broad jump and disc throwing. I'm good at them.

报了跳远和扔铁饼，这是我的强项。

Greek literature describes the many sports that were popular in ancient times; mural s and statues show discus throwers, wrestlers, and charioteer s.

希腊文学中描述了许多古代流行的运动；壁画和雕像中有铁饼运动员，摔跤选手和马车比赛的场景。

The IIA property might not be satisfied in human decision-making of realistic complexity because the scalar preference ranking is effectively derived from the weighting—not usually explicit—of a vector of attributes (one book dealing with the Arrow theorem invites the reader to consider the related problem of creating a scalar measure for the track and field decathlon event—eg how does one make scoring 600 points in the discus event "commensurable" with scoring 600 points in the 1500 m race) and this scalar ranking can depend sensitively on the weighting of different attributes, with the tacit weighting itself affected by the context and contrast created by apparently "irrelevant" choices.

该协会的财产可能不能满足人类的决策现实的复杂性，因为标偏好排名实际上是来自加权，通常没有明确的载体的属性（一本书处理的箭定理请读者考虑有关问题创造一个标措施，田径十项全能比赛，例如如何使一个得分600分，铁饼事件"公"与得分600分， 1500米比赛）和本量排名可以依靠敏锐的加权不同的属性，与默契加权本身受影响的范围和所创造的对比显然是"无关"的选择。

This type of employee is addressed in my Law of the Cross-eyed Discus Thrower: He seldom wins any prizes, but he sure keeps the crowd on its toes.

我的《对视眼铁饼运动员的规则》中队这类员工已作了说明：他很少赢得任何奖项，但众人的命运却在他的足尖上。

WuJian who won the silver in the third youthful world championship of track and field events is selected as my research object.The synchronism images were taken by two JVC9800 high-speed cameras in 200fps and analyzed by the SIMI-motion video analytical system.

选定江苏省青少年男子铁饼运动员吴健为研究对象(第3届世界少年田径锦标赛掷铁饼银牌获得者)，采用两台JVC9800高速摄像机以200fbs的速度同步拍摄，并采用SIMI-motion录像解析系统进行图象解析。

By the near scenery dynamic stereophotography to shoot, and the cinematics data were analyzed with three-dimensi0nal kinematics analysis system, investigating questionnaire was conducted in 32 athletes.

选取第八届全运会前16名男子铁饼运动员和河北省中学生运动会前16名男子铁饼运动员作为研究对象，采用近景动态立体摄影进行拍摄，采用爱捷运动录像解析系统分析获得运动学数据。

Wattley coined the term "Turquoise Discus" in reference to the bluish green colour of the striation of his discus.

Wattley小姐形成了术语"绿松石铁饼"关于他的铁饼的线状的蓝绿颜色。

The different posture, often expressed the different content, takesthese is famous said by the artificial model sculpture, Luo Dan"Thought" is sits, submissive, makes the ponder to meditate the shape;Denmark "Beautiful Manatee" is partly lies, visual distant place,expectation happy future; Rice open and bright Kilo "David" is stands,grips tightly the stone, just and the enemy carries on thelife-and-death fight; Mi Long "掷铁饼" is the side bends the waist,in the savings strength, is doing throws front the final preparation.

不同的姿势，往往表示著不同的内容，就拿那些著名的以人为模特的雕塑来说，罗丹的《思想者》是坐著的，低眉顺眼，作沉思默想状；丹麦的《美人鱼》是半卧著的，目视远方，憧憬著幸福未来；米开朗基罗的《大卫》是站著的，紧握石块，正和敌人进行殊死的搏斗；米隆的《掷铁饼者《是侧弯著腰，在积蓄著力量，做投掷前的最后准备。

The theoretical and experimental investigations of discus flight indicate the following useful conclusions:the optimum combination of throw angle and discus inclination angle is 35°/26°at zero wind,while 45°is not the best release angle due to the aerodynamic force;different combinations of throw angle and inclination angl...

由于气动力的作用，45°并非铁饼的最佳投掷角度，实验和理论研究表明：无风时35°/26°的投掷角/倾角组合最佳；顺风和逆风投掷必须采用不同的投掷角/倾角组合才能获得当地条件下的最好成绩；铁饼出手时25r/s的自转速度已经可以满足稳定性的要求。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
