On the Secure Parabola

摘要: 介绍了确定安全抛物线的4种不同方法，即通过确定曲线族包络线的分析方法，判定一元二次方程重根条件的代数方法，寻找沿斜面最大射程的极值方法和包络线构造的几何方法. 从代数、几何和力学等不同角度讨论了安全抛物线的性质.

Abstract: This paper has introduced several methods determining the secure parabola of projectiles, and discussed its properties of geometry and mechanics from different point of views.
