Modeling of turing structures in the chlorite--iodide--malonic Acid--starch reaction system.

摘要: Recent experiments on the chlorite-iodide-malonic acid-starch reaction in a gel reactor give first evidence of existence symmetry breaking, reaction-diffusion structures predicted by Turing 1952. A five-variable model that describes temporal behavior system is reduced to two-variable model, and its spatial analyzed. Structures have been found with wavelengths are good agreement those observed experimentally. The plays key role binding iodine species, thereby creating necessary difference effective diffusion coefficients activator inhibitor iodide chlorite ions, respectively.
