| 摘 要： | 田径竞赛规则和田径设计手册所示的掷链球护平面图设计不同，而数据相等，这不合数学常理， 在实践中也行不通，必将给竞赛准备工作带来混乱。用数学解析法得出：无论田径竞赛规则还是田径设施手册中掷链护笼平面图的规格均不能全部实现。将部分规格修改则能达到规则精神的主要要求：1．删去图中原规格“4m”的要求；2．田径设施手册中每块挡网宽改为至少2.746m图中图中心至挡网垂直距离改为3.25m。

| Abstract: | Hammer cage plane designs in track and field competition rules and in track and field facility pamphlet are different while the data are the same. It is abnormal,impractical and troubles the competition preparatory work. With mathematical analysis,the authors found that the hammer cage plane standards in whether the track and field competition rules or in track and field facility pamphlet were inaccurate. Therefore,the requirement for 4 meters in the picture was changed into 2 746 meters and the vertical distance from the center of the cage to the net was made into 3 25 meters. |
