为了达到较高的臭氧浓度和臭氧生成效率，提出了一种叠加式臭氧发生器。在相同的反应体积上同时施加高脉冲电压和60hz交流电压，以提高在宽放电间隙下的臭氧生成率。由表面放电和脉冲电晕放电组成的叠加放电的臭氧浓度约为单独放电的两倍。观察到，叠加放电扩展的截面在最大时约为20%。由于电子温度的升高，叠加放电的发射强度最大时约为单独放电的2倍。放电区域局部电场的增大引起了叠加效应。
A superposition type ozonizer has been proposed to achieve relatively high ozone concentration and high ozone generation efficiency. A high-pulsed voltage and a 60 Hz ac voltage are simultaneously applied to the same reaction volume in order to improve the ozone generation yield in a wide discharge gap. The ozone concentration of the superimposed discharge consisting of surface discharge and pulsed corona discharge was approximately two times larger than that obtained by an individual discharge. It was observed that the cross-section of the superimposed discharge extended is observed to be approximately 20% at maximum. The emission intensity of the superimposed discharge shows about two times larger than that of the individual discharge at maximum due to the increased electron temperature. The increment of local electric field in the discharge region causes the superposition effect.
