摘要：
A positive pulsed streamer discharge underwater in the rod-to-ring electrode observed by high speed camera was studied in the previous work [Akiyama et al., IEEE Trans. Plasma Sci. 42, 3215 (2014)]. Our observation showed that the pattern of positive discharge was a bush like streamer in both tap water and pure water. The fractal analysis by box-counting method was used to estimate the streamer discharge characteristics. The conclusion showed that (1) the tap water (D = 1.7686) has obviously higher value than pure water (D = 1.6491). (2) In temporal evolution process, the discharge development can be quantified by means of fractal dimensions. Published by AIP Publishing.
