运用原子位形几率波理论对合金中出现的长程有序结构进行了研究。考虑到合金外延生长的特点及合金中相互作用能情况，采用了二维平面模型，并在此基础上提出了平面会构的方法，从而建立起合金外延生长的理论模型，得到了三元Ⅲ一Ｖ半导体合金中所有可能出现的长程有序结构，较好地说明了实验中出现的长程有序现象。
The long-range order structure appearing in the alloy was studied by atomic probability theory. Taking into account the characteristics of alloy epitaxial growth and alloy interaction energy situation, the use of two-dimensional plane model, and on this basis proposed a method of planar conformation, and thus establish a theoretical model of alloy growth, obtained ternary Ⅲ All possible long-range ordered structures in a V-semiconductor alloy are better illustrations of the long-range order phenomena observed in experiments.
