摘要
常压空气辉光放电(APGD)等离子体应用广泛,但对其参数的描述及定量控制尚无可行的方法.为此,设计了常压下空气辉光放电装置,在电极板平面上产生了一薄层等离子体;根据等离子体具有辐射特性,用光栅单色仪对沿面APGD光辐射特性进行测试,获其辐射光谱;对非均匀、非稳定的APGD等离子体光辐射强度进行平均化处理;数据处理结果表明光谱面积积分平均值和光谱最高峰值平均值随APGD加载功率变化呈线性关系.研究结果说明用APGD的光辐射特性与加载功率之间的关系来控制等离子体的产生量是可行的,为有效利用APGD等离子体提供一种简便的途径.
Although atmospheric pressure glow discharge （APGD） is applied in many fields,there is no effective method to describe its characteristic parameters and use it quantitatively, for which something has been done in the paper. The device of APGD in air has been designed and it can produce a thin layer plasma on planar surface. According to the radiation characteristic of plasma,the radiation spectra of the APGD plasma have been acquired by Sp-750i grating spectrograph. The measured optical radiation intensity of non-uniform and unsteady APGD plasma was processed averagely. The result indicates that the area integrating in average under the spectral curve and the highest spectral peak value in average vary linearly with the power applied to plane of APGD. It also shows that it is feasible to control the plasma quantitatively by the relationship between APGD optical radiation characteristic and applied power. This provides a convenient approach for utilizing APGD plasma effectively.
