| 摘 要： | 建立铅球投掷的数学模型,利用灰色关联分析的方法讨论了铅球投掷过程中出手时的初速度v、出手角度α和出手高度h等因素对投掷距离s的影响,利用拟合的方法得到了出手速度和出手角度之间的拟合公式,明确了它们之间的量化关系和铅球投掷的理想出手角度.

| Abstract: | By setting up mathematical models, we discussed the influence of initial velocity v,throwing angleα and height h on the distance of Shot throwing with method of grey incidence degree analysis,obtained the fitting formulas between initial velocity and throwing angle by using method of fitting,then the quantitative relationship of them and the best throwing angle are clear. |
