The mathematical relationship of breakdown voltage of gas discharge in co2 laser excited by rf is derived by using reduced model based on the theory of gas discharge and several physical parameters which influence gas discharge breakdown of laser are pointed out 摘要以气体放电理论为基础，利用简化模型推导出射频激励co2激光器气体放电击穿电压的数学关系式，指出影响激光气体放电击穿的几个物理参量。
