Based on the results of phase plane analysis in paper I and using the technique of linear stability analysis and numerical simulation, the dynamic be- haviour of Schlögl model in CSTR is further analysed. It is shown that, with in- creasing the input concentration x° of species X but fixing the values of other parameters, the system may undergo the bifurcation from one steady state to three steady states and in turn to one steady state again, shown as in Fig.2. Linear stability analysis shows that only one of the three branches of steady states for AFrom the point of view of bifurcation theory, above discontinuous transiton belongs the saddle-node transition, that is, the saddle point and node approach each other, merge into one compliated multiple singular point, and finally disappear and a limit cycle apears. This result would be helpful for explaination of some abrupt transition phenomena between steady state and oscillatory stte observed in some physical-chemical systems, such as B-Z reaction system.
