✦ Synopsis
In 2 closed sllrrcd Bclousov-Zhabollnskil system the oscdlattq state disappears without damping OP the amplitude The state reached shows c~citablli~y when sliver IO~IS ZIJUC added. In addition, an oscillatory state is observed when the stirring of the excitable medum x stopped.

Chemiluminescence (CL) occurs during reactions of several of the components of the CH2 (COOH)rKBr03-MnS04-H2S04 self-sustained system.

The stirriug effect in the BZ reaction with oxalic acid in a closed batch reactor was simulated in good agreement with experiments. Oscillations, lowering of the number of oscillations and the absence of oscillations under strong stirring were all reproduced using a simple qualitative consideration
## Abstract An inorganic compound, NaH~2~PO~2~, has been found to generate temporal chemical oscillations in Belousov–Zhabotinskii type reactions when it is substituted for the organic reducing material. Gaseous products were removed by a constant flow of nitrogen carrier gas. Periodic Br~2~ evolut
