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.

期刊介绍： University Chemistry is an educational research academic journal supervised by the Ministry of Education and co-sponsored by Peking University and the Chinese Chemical Society. It was founded in 1986 and changed to a monthly publication in January 2016. Its purpose is to promote and deepen the reform of university chemistry education and serve to improve the level of chemistry teaching in my country. The main columns are: Today's Chemistry, Teaching Research and Reform, Knowledge Introduction, Chemical Experiments, Teacher-Student Chats, Future Chemists, etc. The journal has been included in many databases such as China Journal Network Full-text Database, Wanfang Database, Taiwan Huayi Database, Chinese Science and Technology Journal Database (Full-text Edition), and American Chemical Abstracts.
