摘要：

Lateral instability in reaction-diffusion fronts of the chlorite oxidation of tetrathionate is studied experimentally in three dimensions. A simple two-variable model based on the empirical rate law of the reaction is utilized to reproduce the experimental observations. The onset of instability does not change by extending the system from two to three dimensions; the natural wavelength associated with the cellular structure, however, slightly decreases.
