【摘要】 在大气压Air/Ar介质阻挡放电中,研究了正方形斑图的特性随空气相对含量χ的变化规律.得到了正方形斑图的空间波长和运动速度随空气相对含量的变化关系曲线.实验发现:不同的放电气隙间距下,正方形斑图的空间波长均随空气相对含量的增大而减小;正方形斑图的运动速度也与空气相对含量的大小密切相关,当空气相对含量约为10%时,正方形斑图的运动速度达到最大值14mm/s.更多还原

【Abstract】 The properties of the square pattern as a function of the relative air content is studied in Air/Ar dielectric barrier discharge system at one atmosphere pressure.The dependence of the spatial wavelength and the traveling velocity of the square pattern on the relative air content is obtained.It is found that the spatial wavelength of the square pattern is decreased with the increased relative air content at different gas gap distances.The traveling velocity of the square pattern is also closely related to the value of the relative air content,which reaches its maximum 14mm/s when the air relative component is 10%.更多还原
