The central object of this work is to explore a method, which can be used toget information of other dynamic variables from the dependent time behaviors of any onedynamic variable in complex systems. The embedding phase patterns of o-NH2C4COOHBZ reaction systems were made based on embedding theorem and the experimental dataof concentration of bromine ion received by computer. A saturated embedding dimensionm≥8 has been shown, and a related BZ reaction mechanics with 10 chemical speciesas dyndric variables was presented and resolved by Gear algorithm. The concentrationswith time of Br- ,Mn3+, HBrO2, HOBr and BrO2, were simulated.
The oscillations of P-H2NC6H4COOH-KBrO3- H2SO4 system are studied. The dual-frequency oscillations are found in this system. Furthermore, the influences of initial reaction conditions (concentrations of reactans and temperature) metal-ion catalysts and several additives on oscillating behaviors are concluded. These experimental phenomena suggested that the dual-frequency oscillations are controlled by two types of mechanism,one is bromide-ion controlling to the lower frequency oscillations, the other is non-brominde ion controlling to the higher ones, in which the substrate radicals play an important role.Moreover, these mechainsms are competing in the reaction system when the situation is fit for each one. Some interpretations about this are approached from the analysis of the composion of substrates and the viriation of potential during the reaction.
