| 摘 要： | 800m抢道标志线从原来划等弧到现在划渐开线的曲线型划法，其理论上是正确的，但在实际操作过程中很难划规范和准确。通过裁判实践、查阅文献和专家座谈，重新计算了切入差并提出将抢道标志线划成直线，并划在第二直、曲段分界线前，优于曲线型划法，能为运动员、裁判员提供更加便利的判定方法，且不影响竞赛的公平性和起跑位置的变化。 |

| Abstract: | It is theoretically correct to change the lane change markings of 800m running from equal arc to involute. However, it is hard to put the markings in their exact places in practice. This paper points out that in order to facilitate the judgement of referees and contribute to the impartiality of the competition, the lane change markings should be drawn as straight lines in front of the second straight and curving bordering lines. |
| Keywords: | track and field 800m run lane change markings straight line type |
