Abstract: The time variation of chemical affinities A_p and entropy production ? of an open Brusselator system has been studied. It was found that the oscillating characteristics of A_p and ? are quite different. While A_p oscillations with a single peak in every period, ? has either a single peak or two-peak oscillations which depend on the kinetic mechanism of oscillation or values of A_p~?. The meaning to study oscillation of thermodynamic quantities was also discussed.

Key words: Oscillation, Chemical affinity, Entropy production
