近年来，由于水体的富营养化，水体表面广泛而频繁地发生蓝藻华（或水华）。这在世界范围内造成了越来越严重的环境问题。本文报道了脉冲流状放电对绿脓杆菌（M. aeruginosa）细胞的影响。绿脓杆菌是一种易于形成水华的蓝藻属。采用直径为30微米的不锈钢针作为点放电电极，距离圆柱体阴极15cm，施加2 μ m的160-kV脉冲。在充满蓝藻细胞的水中（本文称为样品水）获得了脉冲流状放电。从实验结果可以看出，放电使铜绿假单胞菌细胞内的胞内结构囊泡塌陷，细胞的菌落下沉到放电腔的底部并逐渐腐烂
Recently, cyanobacteria blooms (or water blooms) occurred on the surface of water bodies frequently and extensively due to eutrophia of the water. That has posed more and more serious environmental problems worldwide. In this paper, the effects of pulsed streamerlike discharge on M. aeruginosa cells are reported, which are one genus of cyanobacteria and ease to form water blooms. A stainless needle with a diameter of 30 mum was employed as a point discharge electrode, which is 15-cm apart from the cylinder cathode, and a 2-mus 160-kV pulse was applied. A pulsed streamerlike discharge was obtained in the water filled with cyanobacteria cells (named as sample water in this paper). From the experimental result, it can be found that the discharge collapsed the intracellular-structure gas vesicles in the M. aeruginosa cells, and the colonies of the cells sank to the bottom of the discharge chamber and rotten gradually
