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.
