| 摘 要： | 对3支新规则女子标枪进行气动力风洞试验,通过试验发现新规则女枪的升阻比有所减小,在相同攻角下低头力矩较大,从而使标枪的飞行性能有所下降。但这些变化使标枪裁判工作的客观性和准确性大大增加了。文中还对改进女子标枪的投掷技术进行了分析并提出了建议。

| Abstract: | Three new IAAF woman's javelins were taken experiment in wind tunnel in 1998. The results showed that the ratio of lift and drag was decreased compared with the old javelins. The pitch moment of force was increased at the same attack angles and the flying range of new javelins would be shorten than the old ones. These changes will improve the objectivity and accuracy in refereeing. Suggestions were put forward to improve the technique with the new javelin. |
