In the present work the energy transformation in sonochemical processes is studied by using electrical power measurement techniques and calorimetry. The influence of the ultrasonic amplitude and the properties of the irradiated medium on the efficiency of the equipment is shown. With increasing temperature and increasing solvent vapor pressure less energy can be brought into the fluid. More energy is consumed in high viscous media than in low viscous liquids. Finally the quality of calorimetry is discussed and a new energy-based efficiency factor for sonochemical processes is introduced.
在本研究中，通过使用电功率测量技术和量热法来研究声化学过程中的能量转换。展示了超声振幅和被辐照介质的性质对设备效率的影响。随着温度升高和溶剂蒸气压增加，能够带入流体中的能量减少。在高粘性介质中比在低粘性液体中消耗的能量更多。最后讨论了量热法的质量，并引入了一种基于能量的声化学过程效率因子。
