使用有限晶格的传递矩阵方法计算畴壁自由能的分布。建立了重正化群变换，当晶格参数改变时，它保留了畴壁自由能分布以及磁化率。确定具有最近邻相互作用高斯分布的二维随机 Ising 模型的不动点、临界指数和相图。
The distribution of domain-wall free energies is calculated with the use of a transfer-matrix approach for finite lattices. A renormalization-group transformation is set up which preserves the domain-wall free-energy distribution as well as the susceptibility when the lattice parameter is changed. The fixed points, critical exponents, and phase diagram are determined for the two-dimensional random Ising model with a Gaussian distribution of nearest-neighbor interactions.
