Turbulent eddies in high pressure microsecond spark channels in helium were photographed by means of a 20-nsec Kerr cell shutter. Current densities exceeded 10(6) A/cm(2). It was shown that turbulences are initiated from plasma jets originating at the electrodes. The cathode jet is explained by Compton's accommodation theory as extended by Haynes. The observed anode shock wave appears to be the result of a dynamic magnetic pinch.
利用一个20纳秒克尔盒快门拍摄了氦气中高压微秒级火花通道内的湍流涡旋。电流密度超过10⁶安/平方厘米。结果表明，湍流是由源自电极的等离子体射流引发的。阴极射流根据海恩斯扩展后的康普顿调节理论进行解释。观察到的阳极冲击波似乎是动态磁箍缩的结果。
