铅球投掷角度和最大成绩的函数关系

Relation Between the Anghe of Shotput and the Maximum Projetile Range

为了解决铅球适宜投出角度公式与实践偏离的问题 ,采用抛体运动及数学分析的方法探讨了铅球成绩与抛体最大射程的函数关系 ,得出了最大成绩定理、最佳投出角度公式和最佳出手角度标志线参数式 ,从数学上证明了“与手角对应的轨迹角等于 4 5°会有最大投掷成绩”的判断。

In order to solve the problem of deviation of suitable angle and the practice of shot put, the author analyzes the function relation between performance and the maximum projectile range with the method of projetile and mathmatic aualysis.New optimum angle formula and sign-line parameter are given. When Releacg of shut sultable for the projetile anle is 45°,the maximum prijetile mage can be obtained.
