摘要
首次提出振荡管气柱谐振概念。对气柱谐振机理、条件、有关因素对谐振激励频率的影响及谐振状态下管内振荡流特性进行了探讨。结果表明：气柱谐振与管内激波运动有关；谐振状态下管内出现最强的压力波并产生最强的冷效应和热效应。
A new concept, gas column resonance, was established. The mechanism and condition of gas column resonance, the influences of some factors on resonant frequencies, and the resonant features were investigated. The results show that the resonance is connected with the movement of the shock wave. The pressure wave strength, the cooling effect and heating effect of the tube are the strongest in a state of resonance.
