摘要：

A multispecies reactive lattice-gas automaton model is constructed and used to study chemical oscillations and pattern formation processes in a spatially distributed two-dimensional medium. Both steady state and oscillatory dynamics are explored. Nonequilibrium spatial structures are also investigated. The automation simulations show the formation of rings of chemical excitation, spiral waves, and Turing patterns. Since the automaton model treats the dynamics at a mesoscopic level, fluctuations are included and nonequilibrium spatial structures can be investigated at a deeper level than reaction-diffusion equation descriptions.
