摘　　要：对于抛射体运动,在考虑到介质的阻力影响时,射程与抛射角之间的关系不易求得解析解,通过数值计算的方法,得出了在不同的阻尼系数和初速率下,最大射程与抛射角之间的关系.For movement of projectile, the analytic solution is difficult to be reached, which is used to define the throw and projectile angle if we consider the influence of medium. In the paper the relationship, between maximum throw and projectile angle, under the condition of the different damping coefficients and initial velocities is reached by the method of digital calculation.

关 键 词：阻尼系数 抛射角 射程
