压力的突然降低会触发液体介质内蒸汽和气泡的形成（也称为空化）。这导致许多（关键）工程问题：材料损失，噪音和水力机械的振动。另一方面，空化是一种潜在的有用现象：极端条件越来越多地用于各种各样的应用，如表面清洁，增强化学和废水处理（细菌根除和病毒灭活）。尽管取得了重大进展，但对空化作用机制的理解与其应用之间仍存在很大差距。尽管工程师们已经将利用空化的设备商业化，但我们仍然无法回答一个根本问题：气泡清洁、消毒、杀死细菌和增强化学活性的机制究竟是什么？本文是一个彻底的审查最近（从2005年起）在空化辅助微生物的破坏领域所做的工作，旨在作为一个基础，在未来几年的建设。
A sudden decrease in pressure triggers the formation of vapour and gas bubbles inside a liquid medium (also called cavitation). This leads to many (key) engineering problems: material loss, noise, and vibration of hydraulic machinery. On the other hand, cavitation is a potentially useful phenomenon: the extreme conditions are increasingly used for a wide variety of applications such as surface cleaning, enhanced chemistry, and wastewater treatment (bacteria eradication and virus inactivation).Despite this significant progress, a large gap persists between the understanding of the mechanisms that contribute to the effects of cavitation and its application. Although engineers are already commercializing devices that employ cavitation, we are still not able to answer the fundamental question: What precisely are the mechanisms how bubbles can clean, disinfect, kill bacteria and enhance chemical activity?The present paper is a thorough review of the recent (from 2005 onward) work done in the fields of cavitation-assisted microorganism’s destruction and aims to serve as a foundation to build on in the next years.
