摘要
An electric discharge phenomenon in a high-intensity ultrasound field is influenced by a vibration from a medium in a boundary layer of an electrode. Static pressure is also a component that affects the discharge phenomenon. An intermittent spark discharge unit was set in a high-intensity standing wave field at 164 dB SPL and waveforms of electric discharge were measured. It was found that a prebreakdown current wave existed in a pilot plant; this is one of the important factors for describing the mechanism of the discharge in a high-intensity standing wave field.
