摘　　要：研究斜抛运动,得到忽略空气摩擦和考虑空气摩擦两种情况的运动方程,从形式上看,考虑空气摩擦(f=-kv)的运动方程,当k=0时,与忽略空气摩擦的运动方程不一致.从其参数方程极限的角度考虑,从射程角度考虑,忽略空气摩擦和考虑空气摩擦两种情况并不矛盾,当k→0时,考虑空气摩擦的运动方程趋向于忽略空气摩擦的运动方程.There are two motions of equation that neglecting air friction and considering of air friction, by studying parabolic motion. For form these two motions of equation are difference when k=0. From limit of parametric equation and rang of fire, it is no contradiction between neglecting air friction and considering of air friction. When k→0,the motion equation of thinking of air friction tends to the motion equation of neglecting air friction.
