建立了一个模拟水中纳米脉冲放电气泡的零维模型。该模型由气相和液相组成，分别对应于气泡的内部和外部。研究了化学物质通过气泡界面从气相向液相的扩散。初始气体是Ar，但在气泡中包含少量h2o和o2。作为水处理的重要物质，主要研究了液相中OH浓度的时间演化。结果表明，氢氧根在气泡中生成，然后扩散到液体中。采用连续纳米脉冲放电，在一定的功率消耗下，随着频率的增加，产生的OH自由基增多。
A zero-dimensional model to simulate a nano-pulse-discharged bubble in water was developed. The model consists of gas and liquid phases corresponding to the inside and outside of the bubble, respectively. The diffusions of chemical species from the gas to the liquid phase through the bubble interface was also investigated. The initial gas is Ar, but includes a little H 2 O and O 2 in the bubble. The time evolution of the OH concentration in the liquid phase was mainly investigated as an important species for water treatment. It was shown that OH was generated in the bubble and then diffused into the liquid. With the application of a continuous nano-pulse discharge, more OH radicals were generated as the frequency increased at a low voltage for a given power consumption.
