In this paper, a spectrum analysis system with high sensitivity has been set up, and corona spectra in air were obtained under several different discharge conditions. 本文建立了一套高靈敏度的光譜分析系統，對空氣中幾種不同放電條件下的電暈放電進(jìn)行了光譜分析。
A plasma arc loudspeaker or plasma-dynamic loudspeaker is a loudspeaker that creates sound by varying air pressure through a corona discharge or electric arc. 等離子弧喇叭，又名等離子動(dòng)態(tài)喇叭，是一種通過(guò)電暈放電或電弧改變空氣壓力發(fā)聲的喇叭。
