In order to probe the aqueous reaction mechanism of liquid-phase diaphragm glow discharge (LDGD), radicals formed during the discharge were analyzed by their emission spectra. Emissions of H atoms and OH radicals were observed when the applied voltage was above 700 V. When the applied voltage increased to 750 V, emissions of O atoms were additionally detected. The emission intensities of these radicals and atoms increased with increasing applied voltage. The average electron temperature and the mean electron density of the LDGD plasma were 1. 3 X 10(4) K and 7.8 X 10(17) cm-3, respectively.
为了探究液相隔膜辉光放电（LDGD）的水相反应机理，通过发射光谱对放电过程中形成的自由基进行了分析。当施加电压高于700 V时，观察到了H原子和OH自由基的发射。当施加电压增加到750 V时，还额外检测到了O原子的发射。这些自由基和原子的发射强度随施加电压的增加而增加。LDGD等离子体的平均电子温度和平均电子密度分别为1.3×10⁴ K和7.8×10¹⁷ cm⁻³。
