The complex dynamic behaviors, especially the behavior of transition betweendifferent states, of a closed reaction system which involves only bimolecular reactionsteps (A + B→C + D, B + C→2C) and unimolecular ones (B→P, E→A, G→B, A→D,C→P), is studied. By using the quasi-steady state analysis, a quasi-steady state bi-furcation diagram, which predicts the existence of bistability between two differentsteady states or between a steady state and an oscillatory one, is obtained and con-firmed by numerioal simulations....

The complex dynamic behaviors, especially the behavior of transition betweendifferent states, of a closed reaction system which involves only bimolecular reactionsteps (A + B→C + D, B + C→2C) and unimolecular ones (B→P, E→A, G→B, A→D,C→P), is studied. By using the quasi-steady state analysis, a quasi-steady state bi-furcation diagram, which predicts the existence of bistability between two differentsteady states or between a steady state and an oscillatory one, is obtained and con-firmed by numerioal simulations. The numerical simuiations show that various transitionphenomena between different states may occur in such a closed system, some of thetransitions are trigged by external perturbations, and some may occur spontaneously.The numerical simulations also show that the system may exhibit the phenomena ofexcitation. All these phenomena are similar to those observed experimentally inrealistic closed reaction systems.
