The CSTR-BZ reaction system described by SNB model, in which oscillatory dy
namics is varied with flowrate k(f), is studied by stochastic analysis, The
implication of the minimum reaction concentration is discussed, and the co
ntinuous effect of flow rate is also investigated. Comparison with determin
istic analysis approach and the results of experiment in CSTR-BZ reaction s
hows that deterministic description based on mass action law can still be a
pplied effectively.
