摘要
将一维ＣＡ的动态演化时空图与二维Ｉｓｉｎｇ自旋位形等同起来，用重整化群方法计算得到各向异性三角晶格Ｉｓｉｎｇ模型的临界点发生在无序线ｅ－２Ｊ＝ｃｏｓｈ（２Ｄ）上，这与平衡统计力学计算结果一致；同时求得了相关指数的初步结果。
The evolution dynamics of 1 D probability cellular automata is mapped onto a two dimension Ising Spin configeration. By means of real space renormalization group method,it found that the phase transition point in the inhomogeneous triangle Ising lattice model is on the disorder line e -2J =cosh( 2D) ,and that is agreement with classical equilibrium statistics. Some relevant indexes are preliminarily obtained. Computer experiments support these results qualitatively.
