OH and O radicals are successfully generated in the original and improved multiple bubble jet systems with pulsed discharge. Then water treatment characteristics such as decomposion of harmful persistent substances in solution were clarified experimentally. The dynamic behavior of bubble jet with discharge, streamer propagation at the bubble interface and radicals generation in the treated solution were investigated. The docomposition rate and energy efficiency of methylene blue and acetic acid were clarified for the applied voltage, duty ratio, frequency, gas flow rate and systems configuration for the optimized water treatment processes. Furthermore, the dynamic behavior model of bubble in a fine tube under DC discharge was proposed by visulalization analysis. Finally, plasma chemistry model was also established to clarify the radical generation process and radical life time in a bubble with high pressure and high temperature conditions.

OH和O自由基在原始和改进的具有脉冲放电的多个气泡喷气系统中成功产生。然后，通过实验阐明了水处理特征，例如溶液中有害持续物质的分解。研究了气泡射流的动态行为，并研究了处理溶液中气泡界面处的流式传播和自由基的产生。对于优化的水处理过程，阐明了亚甲基蓝和乙酸的滴定速率和能效，以阐明甲基蓝和乙酸的滴定速率和乙酸的能效。此外，通过粘性分析提出了在直流排放下的细管中气泡的动态行为模型。最后，还建立了等离子体化学模型，以阐明具有高压和高温条件的气泡中的激进生成过程和根治性的寿命。
