由于奥斯特瓦尔德熟化和凝聚在亚稳介质中的相变过程的最后阶段的组合效应的颗粒粗化的演变被认为是。在特殊的自相似变量下，对于过饱和溶液和过冷液体，得到了具有记忆核的积分微分方程的完全解析解。结果表明，随着亚稳能级的降低，粒子分布函数变窄，呈钟形分布。得到的解析解与实验数据符合得很好。
The evolution of particle coarsening due to a combined effect of Ostwald ripening and coagulation at the concluding stage of phase transition processes in metastable media is considered. A complete analytical solution of integro-differential equations with a memory kernel is found in special self-similar variables for supersaturated solutions and supercooled liquids. It is shown that the particle distribution function becomes narrower and bell-shaped when decreasing the metastability level. The analytical solutions obtained are in good agreement with experimental data.
