利用了自旋１／２二维Ｉｓｉｎｇ模型及其“不等式方法”，确定了三元Ⅲ─Ｖ半导体会金（００１）面外延生长中的二维平面基态有序结构和基态相图，并通过层状叠加得到了合金中可能出现的长程有序结构，较好地说明了实验发现的（００１）衬底外延生长中的长程有序现象．
By using the spin 1/2 two-dimensional Ising model and its “inequality method”, the two-dimensional planar ground state ordered structure and ground state phase diagram of the ternary III-V semiconducting gold (001) The layered superposition gives the possible long-range ordered structure in the alloy, which well illustrates the long-range order in the (001) substrate epitaxial growth experimentally.
