摘要
本文根据园内接正六边形的性质,提出了400米半园式田径场增加基准点的设想。笔者认为400米半园式田径场如果增加基准点南①、南②、北①、北②,对400米跨栏跑第一道栏位的丈量,以及对4×100米接力跑接力区的丈量具有拉线短,丈量速度快,丈量准确,操作简便等特点。
According to the characteristic of a circular inseribed regular hexagon, this paper proposes an idea of bettering the 400-metre semi - circular trackfeld ground by adding base-points to it. The author holds that if base points South 1,South 2,and North 1, North 2, are added to the 400-metre semi-circular track-field ground, the measurement of the positions of the first-track hurdles and the 4×100-metre relay take-over zones will be quicker, more accurate and simpler in operation and distancc-measur ing.
