摘　　要：用雨滴与气体分子碰撞模型来描述雨滴所受阻力,分析雨滴的收尾速度。提出在未达到收尾速度前雨滴加速度是均匀递减的假设,根据这一假设,并且利用已得出的雨滴收尾速度,分析雨滴在未达到收尾速度前的运动。A supposihion which is ＂During the raindrop extreme speed have not achieved, the raindrop accederation is progressive decrease evenly. ＂was proposed. According to this supposition, and use rnown raindrop extreme, the raindrop monement which during the raindrop extreme speed have not achieved was analysed. According to this supposition which is decreased progressively when the raindrop achiered in front,the final rate o frain drop has been obfained.

关 键 词：雨滴 收尾速度 气体分子 碰撞
