铅球最佳投出角问题新探

摘要

为了解决铅球适宜投出角度公式与实践偏离的问题，分析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、“新”最佳投出角度公式和最佳出手角度标志线参数式。抽样检验和空气动力学实验指出，新公式能够准确地描述出高、中、低各种水平铅球运动员的适宜出手角度。%In order to solve the problem of deviation of suitable angle andthe practice of shot put, the author analyzes the function relation between performance and the maximum projectile range, draws the best result theorem that is new optimum angle formula and sign-line parameter. The sampling test and aeromechanics experiment provers that the new formula is able to exactly draw the suitable angle for every shot-putter.
