摘要
本文通过运用数学原理计算,指出国内外现行田径规则中抢道线的画法使运动员的跑距不等。该文建议运用第二直曲段交界线为抢道线,把各道的切入差增加到起点前伸数中使各道运动员跑距相等的新画法。
This article, through calculating with mathematical principle, pointed out that drawing the line of leaving one's own lane made athletes' running distances unequal in the current athlettic rules both in China and abroad. Therefore, a new drawing method was suggested in the paper.
