基于一维流体模型，对常压下He-N2混合气体中不同氮杂质含量对阻挡放电的影响进行了数值研究。电流密度随N2杂质量的变化特征表现出一个过渡点。特别研究了施加电压的幅值和频率对过渡点N2杂质量和电流密度的影响。得出以下结论。当外加电压频率固定时，N2杂质量和过渡点电流密度随外加电压幅值的增加而增加。在外加电压幅值固定的情况下，过渡点N2杂质量随外加电压频率的增加而增加，但电流密度的最小值受频率的影响不明显。特别地，在本模拟条件下，观察到了过渡点的Townsend放电模式。
The influence of different amounts of nitrogen impurity on the barrier discharge at atmospheric pressure in He-N2 admixture gas has been numerically studied based on a 1-D fluid model. The characteristic of the current density versus N2 impurity amount shows a transition point. The influence of the amplitude and frequency of the applied voltage on both N2 impurity amount and the current density at the transition point has been particularly investigated. The following conclusions are given. For fixed frequency of the applied voltage, both N2 impurity amount and the current density at the transition point increase with increasing amplitude of the applied voltage. Fixing the amplitude of the applied voltage, N2 impurity amount at the transition point increases with increasing frequency of the applied voltage, but the minimum value of the current density is not evidently affected by the frequency. In particular, the Townsend discharge mode is observed at the transition point under the present simulation conditions.
