为了探讨电源频率对介质阻挡放电（DBD）脱除NOx能耗的影响,利用适用于混合气体、时变电场的玻尔兹曼输运方程计算了DBD放电时的电子动能概率密度、电子平均动能与电源频率的关系,并进行了不同频率的同轴双阻挡介质DBD脱除NOx试验研究.结果表明：在频率小于1GHz时,改变频率基本不影响电子动能概率密度和电子平均动能;频率大于1 GHz时,随着频率的升高,电子平均动能下降;在试验范围内（10~20 kHz）,频率基本不影响脱除NOx的能耗;在进行电源设备频率选取时,可着重从频率对电源设备的初投资、功率输出及体积大小方面的影响考虑.

To study the influence of power frequency on energy consumption of NOx removal by DBD（dielectric barrier discharge） technology,the Boltzmann transport equation,which is applicable for gas mixture subject to time-varying excitation field,was used to analyze how the electron energy probability density and the electron mean energy varying with the power frequency during DBD process,while an experimental study on NOx removal carried out in a coaxial dual-layer DBD reactor under different frequency conditions.Results show that when the power frequency is less than 1 GHz,it hardly affects both the electron energy probability density and the electron mean energy;the electron mean energy reduces with rising power frequency when the frequency is above 1 GHz.In the experimental range of frequency（10-20 kHz）,energy consumption of NOx removal is basically not affected by the frequency,therefore it is recommended to determine the operation frequency of power supply equipment with focus on the initial investment,power output and size of the equipment.
