摘　　要：用自制改进的介质阻挡放电连续处理纺织材料的装置 ,采用示波器李萨如图形测量放电功率 ,分析了常压等离子体放电的极板充电电流和放电功率等电学参量间的变化关系 ,研究结果表明 :放电间隙、工作气体成分和流量均会影响这些电学参量 ,当放电间隙 1.0～ 2 .5mm时 。Recently, the dielectric barrier discharge (DBD) plasma at atmospheric pressure has become higher and higher with its ever increasing applications to surface modification of materials. The relationships among those electricity parameters, such as discharge current and discharge power which is measured by Lissajous figure of the oscilloscope, are analyzed by using improved dielectric barrier discharge equipment. The experimental results indicate that discharge gap, working gas and the rate of flow all have influence on these electricity parameters. The 1.0～2.5mm discharge gap is optimum for surface modification of materials. The result is of great importance to dielectric barrier discharge at atmospheric pressure and its application to surface modification of textile materials.
