Ultrasound induced cavitation (acoustic cavitation) process is found useful in various applications. Scientists from various disciplines have been exploring the fundamental aspects of acoustic cavitation processes over several decades. It is well documented that extreme localised temperature and pressure conditions are generated when a cavitation bubble collapses. Several experimental techniques have also been developed to estimate cavitation bubble temperatures. Depending upon specific experimental conditions, light emission from cavitation bubbles is observed, referred to as sonoluminescence. Sonoluminescence studies have been used to develop a fundamental understanding of cavitation processes in single and multibubble systems. This minireview aims to provide some highlights on the development of basic understandings of acoustic cavitation processes using cavitation bubble temperature, sonoluminescence and interfacial chemistry over the past 2-3 decades.
超声空化（声空化）过程在各种应用中被发现是有用的。几十年来，来自不同学科的科学家一直在探索声空化过程的基本方面。有充分的文献记载表明，当空化泡崩溃时，会产生极端局部的温度和压力条件。已经开发了几种实验技术来估计空化泡的温度。根据特定的实验条件，观察到来自空化泡的光发射，称为声致发光。声致发光研究已被用于深入了解单泡和多泡系统中的空化过程。这篇综述旨在提供过去 2-3 十年中使用空化泡温度、声致发光和界面化学来发展对声空化过程的基本理解的一些要点。
