Oxidation effects of SO2 and by gas discharge were studied. Powers of both DC and DC superimposed AC were used to generate gas discharge.
研究气体放电对SO2和亚硫酸盐氧化的影响，采用了直流电源和交直流叠加电源进行气体放电。
By using power of DC superimposed AC, oxidation rate rose with increase of voltage but had nothing to do with frequencies in this experiment.
利用该统一模型，分析了外加直流电压法、外加交流电压法、乒乓切换法中电刷接触电阻对励磁绕组接地电阻测量值的影响和危害。
It can also be used to measure the AC voltage signal with superimposed DC component.
能测量含有直流分量的交流电压信号。
