摘要 采用双水电极介质阻挡放电装置,在大气压氩气放电中得到螺旋波斑图,并对其局域波长特性进行了研究.实验发现,螺旋波波长具有保持不变的特性.由于多普勒效应,螺旋波局域波长将随平均波长而发生变化.当其改变超出某一临界值时,螺旋波斑图的局域条纹则会产生断层,使其重新恢复到螺旋波平均波长附近.为进一步证实此特性,实验给出了螺旋波局域波长的相对变化量随平均波长变化的关系曲线. The spiral pattern is obtained in atmospheric argon discharge and the local wavelength of which is studied by using dielectric barrier discharge system with water electrodes.It is found that the spiral wavelength has invariability.The local wavelength of spiral patterns will change with the average wavelength changing due to the Doppler effect.If the variation of the local wavelength goes beyond a critical value,the dislocations will appear at local stripe to make the local wavelength return to the average ...
