摘　　要：介绍了B-Z(Belousov-Zhabotinsky)振荡反应实验.在数值模拟中,根据基于FKN机理的Oregonator振子模型对开放体系进行了动力学分析,得到了反应体系的非线性动力学行为;由二维Tyson模型,用差分方法模拟了靶波、双螺旋波的形成过程.实验中,在封闭的系统中对维生素C的浓度进行了分析检测;在自制的简易开放系统中对反应体系的非线性行为进行了观察;采用割断靶波的方法产生了双螺旋波,同时也观察到了单螺旋波与破碎的螺旋波.An innovative experiment named B-Z oscillating reaction is introduced. According to Oregonator＇s model based on FKN mechanism, dynamics analyses on the system are carried out and nonlinear behaviors are obtained. According to the two-dimensional Tyson＇s model the target wave and spiral wave are simulated with difference method. In experiments, the concentration of vitamin C is determined in closed system. The nonlinear behaviors are studied in a simple open system. Moreover, in a close system, a spiral pair is formed by cutting out a target wave. The single spiral wave and broken spiral wave are also observed.
