引言风的阻力在一些个人体育项目中,包括自行车、跑道跑(短跑)和跳远,是影响成绩的一个重要因素。通常,为了获得最好的成绩,朝着与风向一致的方向运动是有利的。为取消这个有利因素,在某些径赛或田赛项目,如果顺着跑的或跳的方向有太大的风的分量时,纪录将不被承认。铁饼的飞行也受到风的影响,但它不同于大多数其它的田径项目,有意思的是,当风面向着投掷方向吹来时,铁饼投手可以比在无风的情况下或者风与投掷方向相同的情况下投得更远。当投掷得法时,一只铁饼就是一个翼型,气动升力的补偿超过了阻力而引起的成绩损失。铁饼爱好者们已经注意到这似乎不合情理的结果有多年 INTRODUCTION WIND RESISTANCE In some personal sports events, including cycling, runway running (sprinting) and long jump, it is an important factor affecting performance. In general, it is advantageous to move in the direction of the wind for the best results. In order to eliminate this advantage, in some track or field events, the record will not be accepted if there is too much wind component along the running or jumping direction. The discus flight is also affected by the wind, but unlike most other track and field events, it is interesting to note that the discus pitcher may be the same as the windless or wind-throwing throw as the wind blows toward the throwing direction The case of further investment. When throwing a law, a discus is an airfoil, and aerodynamic lift compensation compensates for the loss of performance over resistance. Discus fans have noticed this seemingly unreasonable result for years
