摘要：

We present and solve a one-dimensional model of periodic precipitation which includes nucleation, growth and ripening processes. This model thus generalizes two important models: the prenucleation-based model of Dee and the postnucleation competitive growth model (CGM) of Feeney et al. By tuning a simple phenomenological parameter, our model smoothly bridges the gap between a nucleation-growth dominated regime and one where ripening is active.
