摘要：

The influence of the domain size on the properties of rotating waves in the NO + CO reaction on a microstructured Pt(100) surface is investigated for circular geometries. Below a critical domain size, determined by the spiral wavelength in an unbounded medium, the frequency of the rotating waves increases substantially due to interaction of the wave tip with the boundary. The phenomena are reproduced qualitatively with a reaction-diffusion model.
