摘要：
We present an exact closed formulation of the reversible diffusion-limited coagulation-growth reactions 2A <--> A with irreversible input B --> A in one spatial dimension. The treatment here accommodates spatial as well as temporal variations in the particle density with a complete account of microscopic fluctuations and correlations. Moreover, spatial and/or temporal variations in the transport and reaction coefficients can be included in the model. A general solution to the reversible process is presented, and we explore the phenomenon of wavefront propagation.
