Abstract: A new chemical oscillating system involving aminoacid——the system of aspartic acid-BrO_3~--Mn~(2+)-Fe(Phen)_3~2-H_2SO_4 has been described and its oscillating feature has been studied. It is shown that chloride ion, bromide ion,acetone, bromine and acrylonitrile inhibit the oscillation. The analysis of reacting products shows that oxalacetie acid and bromooxaiacetie acid are two of the products of this oscillating reaction. According to the experimental facts and the FKN mechanism, the model, called the Br_2-hydrolysis control model, has been proposed. The oscillating figure calculated from this model is in good agreement with the experimental figure. With this model we give the successful explanation of all the experimental observations and the role of the two metal ions in the oscillating reaction is described.
