The kinetics problem of the weight throw during the throwing and flying has been studied.

从理论上对链球投掷和飞行中存在的一些动力学问题进行了研究。

The paper introduces the method of the weight throwing technology analysis by using the system of 3D image analysis.

文章以链球投掷技术分析为范例,介绍了Ariel三维解析系统分析动作技术的方法。

By using two JVC9800 high-speed cameras,the writer recorded female weight thrower s technique and made kinematic analysis on the single or double supporting time,the speed-up distance of weight,the change of gravity and the angle between shoulders and hips.

采用2台JVC9800高速摄影机,对我国优秀女子链球运动员顾原的投掷技术进行拍摄和解析,并对旋转阶段的单、双脚支撑时间分布、链球加速距离、肩髋角、身体重心变化等进行运动学分析与比较。

Rotating velocity is the key for hammer throwing the faster of the rotaing velocity is,the higher of the hammer throw is.

速度是掷链球旋转过程中的主要技术指标,也是提高链球运动成绩的关键。

Mainly by using mathematical modeling methods,the paper predicts scores of Chinese and the world s women triple jump,women pole-vault and women hammer throw(the women s rising events in field).

运用数学建模法为主的方法,对我国和世界女子三级跳远、女子撑杆跳高、女子链球(以上三个项目均为女子新兴田赛项目)的成绩进行预测。
