二维系统的长时间行为进行spinodal分解数值研究的细胞动力学方法的帮助下，没有和有噪声。在这两种情况下，图案的代表性长度尺度表现为l（t）近似tphi，其中指数phi从近似0.28交叉到近似0.33。交叉时间随着噪声幅度的增加而增加。
The long-time behaviour of two-dimensional systems undergoing spinodal decomposition is studied numerically with the aid of a cell-dynamical approach both without and with noise. In both cases, the representative length scale of the pattern behaves as l(t) approximately tphi , where the exponent phi crosses over from approximately 0.28 to approximately 0.33. The crossover time increases with an increase in amplitude of the noise.
