介质阻挡下指纹放电颜色的研究

Study on the Mechanism of Dielectric Barrier Human's Fingerprint Discharge

采用ns脉冲,在暗室中用彩色胶片记录到指纹放电中的蓝色和紫红色光。当脉冲为2ns时,呈蓝色;脉宽为4ns时,呈紫红色。用N2分子的受激状态对此现象进行了解释。同时,根据放电空间电场的畸变,进一步阐述了脉冲宽度对光辐射颜色变化的影响。

Using ns optical pulses and color film, the blue and pink radiations from the human finger print discharge were observed experimentally. The radiations are blue and pink when pulse widths are 2 ns and 4 ns respectively. The mechanism was explained by the N2 molecular excited state and pulse width changes from the electric field aberrant between the discharge space.
