摘要：

A stochastic reaction-diffusion equation, which describes the time evolution of a front of concentration in a chemical system characterized by a single active component and influenced by the presence of external noise, is solved within the small noise approximation. The spatial correlations of concentration are studied. The relationship between the spectrum of the evolution operator and the correlation function is discussed and two examples (the trigger wave and the wave between a stable and an unstable state) are discussed.
