当振荡活塞迫使昆特管中的封闭气体以接近气柱的声共振频率的有限振幅振动时，产生在管中周期性地来回行进的冲击波。还有气体的加热和平均压力的上升。本文提出了一种气体在其“基本”模式下的稳态运动理论，它包括了管壁摩擦和热传导的耗散效应。冲击强度，平均温度和平均压力对活塞振幅，管长，气体粘度和热导率的理论预测的依赖关系是在很好的定性与目前可用的少量实验数据。
When an oscillating piston forces the enclosed gas in a Kundt tube to vibrate with a finite amplitude near an acoustic resonance frequency of the gas column, shock waves are generated which travel periodically back and forth in the tube. There is also heating of the gas and a rise in its mean pressure. In this paper a theory of the steady state motion of the gas in its “fundamental” mode has been devised which includes the dissipative effects of wall friction and heat conduction to the tube walls. The dependence of shock strength, mean temperature, and mean pressure on piston amplitude, tube length, gas viscosity, and heat conductivity predicted by the theory are in good qualitative agreement with the small number of experimental data available at present.
