实验观察和数值模拟的流注发展在SF6-N2气体混合物中进行，并与彼此的结果进行了比较。通过在测量中使用陡前沿方波高电压，可以在流光发展期间保持电场的恒定条件。最小火花放电电压和流注速度从数值模拟得到的实验观察显示出良好的一致性，和流注速度对气体混合比的变化表现出类似的趋势。
Both an experimental observation and a numerical modeling of streamer development in SF6-N2 gas mixtures are performed and the results are compared with each other. By using a steep-front square high voltage in the measurements, it is possible to keep the constant condition of the electric field during the streamer development. Minimum sparkover voltage and streamer velocities obtained from the numerical modeling show good agreement with those from the experimental observation, and the change in the streamer velocity against the gas mixture ratio shows a similar tendency.
