摘　　要：本文提出了利用运动叠加原理分析铅球最佳出手角的简便方法,与传统方法就两种不同情形下求解最佳出手角进行了对比,说明了叠加原理法的简洁性.同时通过对两组理论数据的对比,说明分析铅球最佳出手角可将出手高度视为独立变量.In this work, we promoted a simple method to analyze the best arm angle of shot by the sports superposition principle. Compared with the traditional methods in two different conditions, our method was showed to be concise. Furthermore, through the comparison of two theoretical groups of data, we explained that the shoot height can be treated as an independent variable in analysis of the best arm angle of shot.
