通过蒙特卡罗模拟技术在一维动力学 Ising 模型中研究了旋节线分解的动力学。从随机状态进行相对深度的淬火后，可以清楚地识别出三种动力学状态。早期状态的特征是平均域尺寸的与温度无关的生长，通过潜伏期演变成 t/sup 1/3/ 生长状态。单原子扩散仅在最早的情况下对生长过程很重要。域尺寸分布的缩放特性表明动态缩放的开始发生在最终生长状态开始之后。
The kinetics of spinodal decomposition have been investigated in a one-dimensional kinetic Ising model by Monte Carlo simulation techniques. Three kinetic regimes can be clearly identified following relatively deep quenches from a random state. An early-time regime characterized by temperature-independent growth of the average domain size evolves to a t/sup 1/3/ growth regime via an incubation period. Single-atom diffusion is shown to be important to the growth process only in the earliest regime. The scaling properties of the domain-size distribution indicate that the onset of the dynamic scaling occurs after the final growth regime has begun.
