The emission of N_2 in discharge gap is detected using optical emission spectrophy. The discharge reactor was put in lightproof box to avoid the disturbance from outside lights. A small hole was drilled in one sidewall of the box, and the fibre was mounted coupling to the inlet (1mm) into the hole. A tube with the inner diameter of 1.1mm was set in the front of the hole. In this way, only the light from a certain direction emitted from the discharge reactor could transfer into the inlet through the tube. The reactor could be moved in the vertical direction of the fibre, and the spectrometry can collect the total emission along the fibre inlet in single-shot measurement.

利用光学发射光谱仪对多针对板电晕放电中放电间隙内的N_2发射光谱进行测量，放电反应器置于暗箱中以避免外界对光谱测量的影响，将光谱仪的光纤耦合入口固定在暗箱侧壁的小孔内，小孔孔径为光纤耦合入口直径，在小孔前方安装孔径为1.1mm的细直管，只采集与光纤耦合入口在同一直线上的发光，避免放电区其它区域的发光被同时接收。
