Abstract:

On the basis of Oregonator model, the influence of acid on B- Z oscillating reaction is analyzed, the dynamic regime of B- Z reaction with acid value B and model parameter h (the concentration of NaBrO3 is certain), and the time - series plots、 2- D and 3- D phase plots of each component under different acid conditions are given, and also the curves of acid B vs. oscillating period and amplitude. This made the theory of the threshold values of B- Z oscillating reaction more completely. The experimental results proved that the model is correct.

Key words: Oregonator model, Acid, B-Z oscillating, Linear stability analysis
