基于有机物超声降解的动力学共振模型

为了深化对声化学机理的认识，从声场下空化泡的微观动力学出发，在研究分析现有模型基础上，进一步考虑空化泡的振荡过程及崩溃时界面的传质，提出以共振空化泡为中心的假设，经理论推导建立了新的模型．该模型较深刻表述了实际声化学作用过程，能较准确地反映实际声化学效应和解释各种实验结果．尽管新模型的推导机理与现有模型不同，然而所得到的数学方程与其是等价的，而且从化学动力学深度上拓宽了模型的应用范围，更具普适性．

A Resonant Kinetic Model of Ultrasonic Degradation to Organic Compounds

In order to enlarge the understanding of sonochemical mechanism, based on the cavitation micro kinetics in the sound field and the existing models, paying more attention to the cavitation surging process and the mass transportation during cavitation breakdown, this paper brought out an assumption focused on the resonating cavitation and erected a novel kinetic model by theoretic deduction. The sonochemical process and performance can be easier gained, and more clear understanding to kinds of experimental results. This model, which is different from the existing models in mechanism, leads to an equal mathematical formulation and broadens the applicable area and has more generalization on the aspect of chemical kinetics.
