The PI proposes to continue his investigations into the underlying principles that govern the dynamic behavior of chemical reactors by studying unsteady state behavior. His objectives are to gain insight into chemical processes and to use the results as paradigms with which the understanding of chemical dynamics can be advanced. He plans to look at two systems: electrochemical and two-phase processes. The modelling of the dynamics of electrodissolution of metals can have various forms: one approach is to model the process with ordinary differential equations derived from surface reactions on the electrode surface while other models have as an intrinsic property the diffusion through a film on the electrode surface. The PI plans to look at both types of models and experimentally determine the best one. He also plans to look at the dynamics of electrochemical reactions other than metal dissolution such as the electrochemical catalytic reactions. The dynamics of gas-liquid continuous chemical reactor systems will also be studied. Reaction occurs in the liquid phase and one of the reactants, normally oxygen, is absorbed from a gaseous phase. The PI plans to investigate the effect of reaction on the rate of mass transfer, and consequently, the interaction of enhanced mass transfer with oscillatory behavior. Mathematical models will be postulated and then experimentally verified.

PI建议继续调查潜在的 控制化学反应器动态行为的原理， 研究非稳态行为。 他的目标是深入了解 并将结果作为范例， 可以促进对化学动力学的理解。 他计划研究两种系统：电化学和两相 流程. 电溶解动力学模型的建立 金属可以有各种形式：一种方法是模拟过程 用从表面反应导出的常微分方程， 电极表面，而其他模型具有作为固有特性的 通过电极表面上的膜的扩散。 PI计划 看看这两种类型的模型，并通过实验确定最好的 一个. 他还计划研究电化学 金属溶解以外的反应，如电化学 催化反应 气-液连续化学反应器系统的动力学将 也被研究。 反应发生在液相中，其中一种反应是 从气相中吸收反应物（通常为氧气）。 的PI 计划研究反应对质量速率的影响， 传递，因此，增强传质的相互作用 具有振荡行为。 将假设数学模型， 然后进行实验验证。
