讨论了水中流注引发和电击穿的物理机制。重点是各种过程中，可能导致的成立和传播的拖缆在水中。物理细节与观察到的差距在击穿阳极与阴极，亮度的差异，流光传播速度的变化进行了讨论。创建一个本地化的低密度区域附近的现场增强被证明是必不可少的流光启动。最后，使用一个三点几何结构的三角管型电触发开关被证明是一种低成本，紧凑的替代激光（或声学）开关。这种受控分解可用于各种应用，包括水净化和生物净化。
Physical mechanisms for streamer initiation and electrical breakdown in water are discussed. The focus is on various processes that could lead to the inception and propagation of streamers in water. Physical details associated with observed disparities in breakdown at the anode versus the cathode, differences in luminosity, and variations in streamer propagation speeds are discussed. Creation of a localized low-density region near the site of a field enhancement is shown to be essential for streamer initiation. Finally, the use of a trigatron-type electrically triggered switch with a triple-point geometry is shown to be a low-cost, compact alternative to laser (or acoustic) switching. Such controlled breakdown could be used for various applications including water purification and bio-decontamination.
