摘要：

The emergence, growth and stabilization of stationary concentration patterns in a continuously fed chemical reaction-diffusion system are studied through numerical simulation of the Lengyel-Epstein model. This model represents a key to understanding the recently obtained Turing structures in the chlorite-iodide-malonic acid system. Using the supply of iodine as a control parameter, the regularity of the hexagonal patterns that develop from the noise inflicted homogeneous steady state is examined. In the region where they are both stable, the competition between Hopf oscillations and Turing stripes is studied by following the propagation of a front connecting the two modes. Finally, examples are given for the types of structures that can develop when a gradient in feed concentration is applied to the system.
