摘要对于污染控制，低温等离子体似乎是最方便的高能电子和化学活性物质的来源。在放电中，大气压下的非热等离子体条件可以通过快速气流通过放电室体积来获得，如在DC辉光放电或AC滑动电弧放电中。在给定的等离子体反应器几何结构下，要获得非平衡低温等离子体条件，需要研究电子温度及其体积分布的基本参数。这些条件取决于等离子体气体的种类及其速度、滑动弧反应器的几何形状以及电源系统的参数。本文提出了一种确定双电极滑动弧反应器电子温度及其分布的简化数学模型。计算结果对电源系统参数的选择和设计有一定的参考价值，以保证滑动弧放电等离子体的非平衡状态。进一步计算了三电极和多电极反应器的三维温度分布。
Abstract For pollution control the non-thermal plasma seems to be the most convenient source of energetic electrons and chemically active species. In the electrical discharges the non-thermal plasma condition at atmospheric pressure can be obtained with fast gas flow through the discharge chamber volume, like in DC glow discharge or AC gliding arc discharge. The electrons temperature and its volumetric distribution is one of the fundamental parameters that should be study if we want to obtain the non-equilibrium low temperature plasma conditions in given geometry of the plasma reactor. These conditions depend on the kind of plasma gas and its velocity, geometry of the gliding arc reactor and on parameters of the power supply system. Paper presents a simplified mathematical model of the two -electrode gliding arc reactor to determine electron temperature and its distribution. Results of calculations are useful for selection of the power supply systems parameters and their design as to ensure the non-equilibrium state of gliding arc discharge plasma. Further calculations aim at three-and multielectrode reactors and three-dimension temperature distribution.
