摘要：

A mathematical model of the Belousov-Zhabotinsky (BZ) oscillating reaction is presented along with experimental data showing that the catalyst can remain almost completely oxidized during a significant part of the oscillatory cycle in the ferroin-catalyzed BZ reaction. The model semiquantitatively describes oscillations and wave propagation in both the cerium- and ferroin-catalyzed systems when the phase of catalyst oxidation occupies a significant part of the oscillatory cycle. Such modes are of special interest because they give rise to enhanced instability of the bulk oscillations, enlargement of the number of local wave sources, and decremental wave propagation. Reversibility of the catalyst oxidation by bromine dioxide radicals is crucial for the dynamics of the system under these conditions.
