摘要

对物理化学经典动力学实验Belousov-Zhabotinsky (B-Z)振荡反应进行了重新设计。在新的实验方案中，介绍了基于反应机理的非线性复杂反应动力学的数学处理，以及B-Z反应在银离子检测中的应用。新方案可以加深学生对非线性非平衡动力学和耗散结构的理解。此外，处理复杂动力学的数值方法可用于未来的科学研究和实践。

Redesign of Belousov-Zhabotinsky (B-Z) Reaction, an Experiment in Physical Chemistry

The classical kinetic experiment in physical chemistry, Belousov-Zhabotinsky (B-Z) oscillating reaction, was redesigned. The mathematical treatment of nonlinear complex reaction kinetics based on the reaction mechanism and the application of B-Z reaction in the detection of silver ions are introduced in the new experimental scheme. The new scheme can deepen students’ understanding of nonlinear non-equilibrium kinetics and dissipative structure. Moreover, the numerical method dealing with the complex kinetics can be used in future scientific research and practice.
