在对田径跑道1500m起点放射线丈量法及其测量结果的研究中发现,在使用《田径运动高级教程》中的通用计算公式对部分道次起点位置计算时,不能精确的表述这部分道次距离,造成运动员实跑距离大于1500m,而且此问题在有关书中普遍存在。作者提出,要计算不同半径、道宽、道次田径场中的1500m起点的放射线距离,应在明确“确定点”所在道次位置之后,再对不同道次起点位置采用不同的计算方法,计算出放射线距离,如此才更为科学、合理。
In the research on the measuring method of radiation at the starting point of 1500m in track and field and its measurement results, it is found that when calculating the starting position of partial track by using the general formula in “Advanced Course of Track and Field Sports”, this part of track distance can not be accurately expressed, As a result, athletes’ actual running distance is more than 1500m, and this problem is prevalent in relevant books. The authors propose that to calculate the radial distance from the starting point of 1500m in different radius, track width and track and field tracks, a different calculation method should be adopted for the position of the starting point of different tracks after the position of the track where " , Calculate the radiation distance, so it is more scientific and reasonable.
