Abstract
The experimental study of the process of sound propagation along a positive column showed that the sound amplification in a stationary diffuse dischar ge in nitrogen obeys a linear theory. However, the discharge column contrac tion leads to a jumplike increase in the gain, in agreement with a nonlinea r theory of the sound amplification in a vibrationally excited nonequilibri um molecular gas.
