摘要: 设计了一个数值模型来模拟一个反应物在明胶层中边扩散边在油珠界面上与另一个反应物反应的动力学过程。提出了处理油珠界面反应的动力学方程,并应用在模型设计中。采用模型模拟与动力学实验测量相结合的方法不仅可以获得反应物在明胶层中的扩散系数和界面反应的比速率常数等重要动力学参数,而且可以提供反应物和生成物在明胶层中的时空分布,并预测不同条件下的动力学过程。对模型的适用性也作了详细的讨论。

Abstract: A numerical model was designed to simulate the kinetic process of diffusion and reaction of one reactant with another on the interface of droplets in a gelatin layer. The computing procedure of the model was given and its applicability was discussed. Using the combination of the model with experimentally kinetic measurements, the diffusion coefficient of the reactant in gelatin medium and the specific rate constant of the interfacial reaction could be determined and meanwhile the time and spatial distributions of reactants or product in a gelatin layer could also be obtained. When the necessary parameters were available, the model could be used to predict the kinetics under various conditions.
