【 摘 要 】

In this paper highlights gas oscillations in the devices consisting of a combustion chamber and a narrow tube for the outflow of combustion products. Considering the sound velocity gradient in the tube. The resulting equation of fluctuations frequency of gas in the test device with any geometrical parameters.
