实验研究了水溶液中局部放电与电导率的关系。使用针-板电极，它已被证明，放电演变成两个阶段。在第一个流光状阶段，放电传播的速度为106厘米/秒，而在第二个电弧状阶段的放电的长度几乎保持不变，虽然电流仍然增加。较高的溶液电导率导致产生较短的通道，在较大的放电电流，并在一个较高的等离子体电子密度。苯酚的降解放电也已被证明。研制了一种表面覆盖一层多孔陶瓷的特殊金属电极，并用于产生多通道放电。在可比的溶液电导率的陶瓷涂层电极产生的等离子体与非常相似的参数的针-板电极配置。多通道放电产生强聚焦冲击波的实验研究
Partial electrical discharges in a water solution as a function of conductivity have been studied experimentally. Using needle-plate electrodes it has been demonstrated that the discharge evolves in two phases. During the first streamer-like phase, the discharge propagated with a velocity of 106 cm/s, while during the second arc-like phase the length of the discharge remained almost constant although the current still increased. Higher solution conductivity resulted in the generation of shorter channels, in larger discharge current, and in a higher plasma electron density. Degradation of phenol by the discharge has also been demonstrated. A special metallic electrode covered by a thin layer of porous ceramic has been developed and used for generation of a multichannel discharge. At comparable solution conductivity the ceramic-coated electrode produced plasma with very similar parameters as the needle-plate electrode configuration. Generation of strong focused shock waves by the multichannel discharge in a...
