通过基于激光纹影法的时间分辨成像，观察了水中脉冲流光放电产生的冲击波的时间发展。这些冲击波的压力是使用休格尼奥方程计算的，该方程利用冲击波压力和冲击波速度之间的关系。通过向针状电极施加脉冲正电压来产生流光放电。测量结果表明，流光放电附近的压力超过 1 GPa。
The temporal development of shock waves generated by pulsed streamer discharges in water was observed by means of time-resolved imaging based on the laser Schlieren method. The pressure of these shock waves was calculated using the Hugoniot equations, which use the relationship between the shock wave pressure and shock wave velocity. The streamer discharges were generated by applying pulsed positive voltages to a needle electrode. The measurements indicate that pressures exceeding 1 GPa occur in the vicinity of the streamer discharges.
