The impact of hydrostatic pressure, commonly known as ambient or external pressure, on the phenomenon of sonochemistry and/or sonoluminescence has been extensively investigated through a multitude of experimental and computational studies, all of which have emphasized the crucial role played by this particular parameter. Numerous previous studies have successfully demonstrated the existence of an optimal static pressure for the occurrence of sonoluminescence and multi-bubble or single-bubble sonochemistry. However, despite these findings, a universally accepted value for this critical pressure has not yet been established. In addition, it has been found that the cavitation effect is completely inhibited when the static pressure is either too high or too low. This comprehensive review aims to delve into the primary experimental results and elucidate their significance in relation to hydrostatic pressure. We will then conduct an analysis of numerical calculations, focusing specifically on the influence of external pressure on single bubble sonochemistry. By delving into these calculations, we will be able to gain a deeper understanding of the experimental results and effectively interpret their implications.
静水压力，通常称为环境压力或外部压力，对声化学和/或声致发光现象的影响已通过大量实验和计算研究进行了广泛调查，所有这些研究都强调了这一特定参数所起的关键作用。先前的许多研究已成功证明存在声致发光以及多泡或单泡声化学发生的最佳静压。然而，尽管有这些发现，但尚未确定这个临界压力的普遍接受值。此外，已经发现当静压过高或过低时，空化效应会被完全抑制。这篇综述旨在深入研究主要实验结果，并阐明它们与静水压力相关的意义。然后我们将进行数值计算分析，特别关注外部压力对单泡声化学的影响。通过深入研究这些计算，我们将能够更深入地理解实验结果并有效解释其含义。
