• The behavior of the sund wave in a positive column of grow discharge is investigated experimentally. When the sound wave propagates in the positive colummn, the amplification of the sound wave is observed. The growth rate of the amplitude and the phase velocity are increased with the discharge current. when the discharge tube is cooled down to the liquid nitrogen temperature, the growth rate increases three times as much as that in the room temperature. The experimental results suggest the sund wave is unstable in the grow discarge.
