Ozone is produced through bonding oxygen molecule and oxygen atom. As dissociation energy of oxygen molecule is about 5eV, if the mean energy of electrons in an electrical discharge is around this value, ozone will be produced most efficiently by electrical discharge. This will be achieved by using positive streamer, discharge, because this discharge has a high field region on the top the streamer head. When a sharp rise pulse voltage is applied to the electrode configuration of thin wire electrode to plane one, streamer discharge start from the wire electrode to the plane one. A special stabilizer of discharge which has two narrow discharge gaps in series connection has been developed to generate high speed pulses. New type ozonizer using this stabilizer of discharge is operated with A.C high voltage and has high efficiency of ozone production, but the yield rate of ozone is low.

臭氧是由氧分子和氧原子结合而成的。由于氧分子的离解能约为5eV，如果放电中电子的平均能量在该值附近，则通过放电将最有效地产生臭氧。这将通过使用正流光放电来实现，因为这种放电在流光头的顶部具有高场区域。当一个陡升的脉冲电压施加到细线电极到平面电极的电极结构上时，流注放电从线电极到平面电极开始。为了产生高速脉冲，研制了一种特殊的放电稳定器。采用这种放电稳定剂的新型臭氧发生器在交流高压下运行，臭氧产生效率高，但臭氧产率低。
