Based on a ten-step chemical model involving the concen- trations of I2(aq), O2(aq), and the intermediates of I - and HIO2, four independent variables and seven irreversible steps, the nonlinear be- havior of Bray-Liebhafsky (BL) oscillating reaction was investigated. The results showed that with different values of initial concentrations of reactants in the process of simulation, both periodic oscillation and chaotic behavior could be observed. In addition, at the same initial concentrations and rate constants, the system becomes more and more regular after being chaos. That is to say, the translation from chaos to pe- riodic oscillation at the same initial conditions appeared in the BL sys- tem. The nonlinear behavior of system was also investigated briefly.
