摘　　要：运用简单波、冲击波理论,通过对气体炮打开后气体在发射管内的运动分析,给出作用在弹丸底部气体压力的最大值,根据冰雹弹丸的物理特性,提出进一步提高气体炮发射冰雹速度的方法。The theory of simple waves and shock waves is applied to analyze the motions of air in the gun tube after the air gun is triggered and the maximal pressure at the buttom of the pill is derived. The methods of speedup are proposed under the limitation of the strength of hailstone pill.
