Abstract

The experimental study of the process of sound propagation along a positive column showed that the sound amplification in a stationary diffuse discharge in nitrogen obeys a linear theory. However, the discharge column contraction leads to a jumplike increase in the gain, in agreement with a nonlinear theory of the sound amplification in a vibrationally excited nonequilibrium molecular gas.
