In this review the phenomenon of ultrasonic cavitation and associated sonochemistry is presented through system parameters. Primary parameters are defined and considered, namely; pressure amplitude, frequency and reactor design; including transducer type, signal type, vessel-transducer ratio, liquid flow, liquid height, liquid temperature and the presence of a reflective plate. Secondary parameters are similarly characterised and involve the use of gas and liquid additives to influence the chemical and physical environments. Each of the parameters are considered in terms of their effect on bubble characteristics and subsequent impact on sonochemical activity. Evidence suggests that via parametric variation, the reaction products and efficiency may be controlled. This is hypothesised to occur through manipulation of the structural stability of the bubble.
在本综述中，通过系统参数介绍了超声空化及相关声化学现象。定义并考虑了主要参数，即压力幅值、频率和反应器设计；包括换能器类型、信号类型、容器与换能器的比例、液体流动、液体高度、液体温度以及反射板的存在。同样对次要参数进行了表征，这些参数涉及使用气体和液体添加剂来影响化学和物理环境。从各参数对气泡特性的影响以及对声化学活性的后续影响方面对每个参数进行了考量。有证据表明，通过参数变化，可以控制反应产物和效率。据推测，这是通过操纵气泡的结构稳定性来实现的。
