Description

One studied theoretically possibility to intensify acoustic waves in inhomogeneous atomic plasma under constant current. The mentioned intensification is caused by transfer of thermal energy from electrons to a colder neutral gas at elastic collisions of electrons with atoms. One derived and analyzed dispersion equation for acoustic waves in inhomogeneous plasma. Comparison of theoretical and experimental results enables to determine reasons of their discordance

Abstract (Russian)

Теоретически исследована возможность усиления акустических волн в неоднородной атомарной плазме при постоянном токе. Это усиление обусловлено передачей тепловой энергии от электронов к более холодному нейтральному газу при упругих столкновениях электронов с атомами. Получено и проанализировано дисперсионное уравнение для звуковых волн в неоднородной плазме. Сравнение теоретических и экспериментальных результатов позволяет выяснить причины их расхождения
