Abstract: So far, almost all systems which show chemical oscillation were discovered by chance.In this paper, we discuss the possibility of designing chemical oscillation by introducing a suitable slow feedback step to a system which shows multiple steady states. A criterion of existence of oscillation solution from kinetic equations for model system is given, and a method to identify the region of oscillation solu- tion in parameter space is proposed. With this method, the mechanism of oscilla- tion phenomena in the oxidation of carbon monoxide on Pt catalyst is analysed.Experimentally, many chemical reacting systems show multiple steady states. A typical situation is shown in Fig.1, where x represents the value of state variable, λ the value of control parameter. The kinetics of the above system can be described bydx/dt=f(x, λ) (1)...
