为了研究同轴线筒电极在大气压下空气中的电气参数和放电机理，利用有限元软件Comsol的等离子体模块，建立了大气压空气中一维线筒电极放电的等离子体模型，并对放电过程进行求解，得到放电过程中气隙的电场强度及电子密度随时间变化的图形，放电过程中电子密度高达1014 m-3，此时对应的放电电流为毫安级。在大气压空气中对线筒电极也进行了放电实验，在不同的外加电压下，测出线筒电极的放电电流分别约为1 mA和5 mA，仿真结果与实验数据相吻合。
In order to study the discharge mechanism and electrical parameters of line-cylinder electrodes in air at atmospheric pressure, we used the finite element software Comsol to establish a one-dimensional plasma discharge model of line-cylinder electrode, and the discharge process was solved. The variation figures of electric field intensity and electron density of gas gap during discharge process with time were obtained, the electron density can increase to 1014 m-3, and the corresponding discharge current is mA level. The discharge experiment of line-cylinder electrode was conducted in air at atmospheric pressure. The measured discharge current is about 1 mA and 5 mA respectively under different applied voltages, and the experimental results are match well with the simulation data.
