对于空气中的表面介质阻挡放电，我们研究了驱动电压的频率对耗散功率，放电电压的幅度的不对称性，放电紫外发射，臭氧产生，与TiO 2放电和磁场中的放电的臭氧产生的影响。我们发现，对于特定的电压，驱动电压频率为26.3kHz时的耗散功率高于驱动电压频率为10.9kHz时的耗散功率，放电电压正半周期的峰值高于负半周期的峰值，波长为320-420 nm的放电紫外辐射强度在两个频率下都是功率的线性函数;对于26.3 kHz的驱动电压的频率，最大臭氧浓度是用比10.9 kHz的频率更小的功率获得的;将TiO 2颗粒放置到放电室中对于由放电产生的驱动电压最大臭氧浓度的两个频率都增加，并且对于26.3 kHz的驱动电压的频率增加臭氧产生产率。最后，磁场对由放电产生的臭氧浓度以及对产量没有可观察到的影响。
For surface dielectric barrier discharge in air we studied the effects of frequency of the driving voltage on dissipated power, asymmetry of amplitudes of the discharge voltage, discharge UV emission, ozone production, ozone production of the discharge with TiO2 and of the discharge in magnetic field. We found that for a particular voltage the dissipated power is higher for the frequency of the driving voltage of 26.3 kHz than for the frequency of 10.9 kHz; peak values of the positive half-periods of the discharge voltage are higher than peak values of the negative half-periods; intensity of the discharge UV emissions for wavelengths of 320-420 nm is for both frequencies a linear function of power; maximum ozone concentration for the frequency of the driving voltage of 26.3 kHz is obtained with smaller power than for the frequency of 10.9 kHz; placement of TiO2 particles into the discharge chamber increases for both frequencies of the driving voltage maximum ozone concentration produced by the discharge and for the frequency of the driving voltage of 26.3 kHz increases ozone production yield. Finally, there is no observable effect of magnetic field on concentration of ozone produced by the discharge as well as on production yield.
