Radiation characteristic measurement of low temperature plasma under atmospheric pressure

本文在自行设计的放电电极板上实现常压下的空气辉光放电(APGD),产生出一薄层的低温等离子体,利用光栅单色仪及测试声强和温度的仪器对所产生的等离子体的光辐射、声辐射和热辐射特性进行实验测量。数据处理后的分析结果表明,该APGD等离子体的光辐射强度及声辐射和热辐射强度,以及总辐射能量基本上都与电极板的加载功率呈线性关系,而且各种形式的能量各占比例是一定的。研究结果表明可以通过沿面APGD的辐射特性与加载功率之间的关系来描述APGD等离子体的特性,以及控制等离子体的产生量。A thin layer of the low temperature plasma due to Atmospheric Pressure Glow Discharge (APGD) in air was produced on the planar surface of designed electrode plates. The optical, acoustic and thermal radiation characteristics of the produced plasma were measured in experiment with a grating spectrograph system, a sound level meter and a non-contact thermometer, respectively. The analysis results from the data processed indicate that the intensity of the optical, acoustical and thermal radiation of the APGD plasma grow linearly up with the increasing power applied to the electrode plate, which demonstrates that the total radiance varies linearly with the power and that every kind of radiant energy has a proper proportion. The study shows that it is feasible to describe the behavior of the APGD plasma and to control it quantitatively by the obtained relationship between its radiation characteristic and applied power.福建省自然科学基金(A0410001
