【摘要】 声化学是一门新兴的交叉学科,具有很多用途,广泛地应用于医药、生物、海洋、航空、轻工、食品、化学、化工等诸多领域,近年来对声化学的研究十分活跃。多频超声对声化学产额的影响是其中研究的热点之一。声化学反应的主动力是声空化,声化学产额与超声辐照频率有一定的关系。双频、三频正交超声辐照能显著地提高声化学产额,具有明显的增强效应。文章综述了这方面的研究进展情况,阐述了声化学产额的影响因素,提出了目前所存在的问题并进行展望。更多还原

【Abstract】 Sonochemistry is a new branch of chemistry with many applications in medicine, biology, marine science, aviation, food industry, chemical engineering, light industries, etc. Researches in sonochemistry are quite active in recent years. A topic of interest is the effect of multifrequency ultrasound on the sonochemical yield. Doublefrequency and threefrequency ultrasonic irradiation can significantly improve sonochemical yield with remarkable enhancement effects. This paper reviews progresses in this area, and analyzes factors that influence sonochemical yield, points out the existing problems, and presents prospects of the future development.更多还原
