介质阻挡放电（DBD）被广泛应用于臭氧发生、废气处理、表面处理等领域。在2008年，我们发现了一种新的大气压汤森放电（APTD）产生在空气中使用氧化铝屏障板。在本研究中，我们使用两个不同放电模式的臭氧发生器，研究放电模式和气体成分对臭氧发生性能的影响。实验结果表明，APTD在空气和纯氧中的臭氧产率几乎相同。我们现在认为，在APTD模式的情况下，电子无法获得足够的能量来有效地解离O2。
The Dielectric Barrier Discharge (DBD) is widely used for ozone generation, exhaust gas treatment, surface treatment etc. In our laboratory, we investigated efficient cleaning methods of diesel exhaust gas by DBD. In 2008, we found that a novel Atmospheric Pressure Townsend Discharge (APTD) was generated in air using alumina barrier plates. In this study, using two ozonizers with different discharge modes, we investigated the effects of discharge mode and gas components to the ozone generation performance. The experiment results showed a peculiar effect that the ozone yields by APTD were almost the same in air and in pure oxygen. We are now thinking that in case of APTD mode, the electrons cannot get enough energy to dissociate O2 efficiently.
