The spectrum radiance in bright and dark region of striation discharge is studied experimentally. 实验研究了条纹放电的明条纹和暗条纹中汞原子的谱线强度。
A new gas detecting method based on the dark discharge current and the character of the pulse current after breakdown was proposed in this paper. 因此,本论文提出暗电流和气体击穿后脉冲电流检测气体的新方法。
In this work, dark discharge current of gas ionization sensor and the character of the pulse current after breakdown were studied other than the decrease of breakdown voltage and breakdown current value, which were main methods for previous research. 本论文避开传统的依靠击穿电压下降和击穿电流值来检测气体的方法,重点研究了场致电离传感器的暗电流和气体击穿后脉冲电流特性。
A new gas detecting method based on dark discharge current was put out and the response mechanism was deeply discussed that the relation between the dark discharge current and the concentration of detected gas was theoretically established and studied. 提出了通过场致电离传感器的暗电流检测气体的新方法,深入研究出了该方法对气体的敏感响应机理,从理论上分析并预测了暗电流与测试气体浓度的关系。
