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. 本文建立了一套高灵敏度的光谱分析系统,对空气中几种不同放电条件下的电晕放电进行了光谱分析。
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. 等离子弧喇叭,又名等离子动态喇叭,是一种通过电晕放电或电弧改变空气压力发声的喇叭。
