摘　　要：本文从研究气枪工作性能最基本的自由气泡振荡理论入手,从理论和现场测试结果两个方面,分析了评价空气枪性能的几个主要指标与气枪工作压力、气室容积及沉放深度的关系,得出2000psi空气枪比6000psi空气枪从能量角度上更加有效的结论。In order to getting a clear idea about relations among main specifications of air gun and its working pressure, air container volume and depth, authors of this paper analyze the theoretical results and testing results after making a thorough study on the basic working principle of air gun, which is called free bubble oscillation principle air gun. Then they reach a conclusion that detonation energy of 2000psi air gun is lager and more effective than that of 6000psi air gun.
