本文应用王氏之理论於平面方格及立方格中AB型超格。所有计算皆作到第二次近似值,惟仅考虑到邻近原子间之相互作用。所计算者有临界温度与合金成分之关系,秩序之程度,内能,及比热。凡Bethe氏曾经计算过者与本文计算结果相较,均相差无几。Wang's generalization of Bethe's theory of snperlattices is applied to the cases of quadratic and simple cubic lattice. Only neighbour interaction is taken into consideration. All the calculations are carried out to the second approximation.The variation of the critical temperature with composition is calculated. The degree of order, the energy and the specific heat are calculated for the special case of equal numbers of A and B atoms at various temperatures. It is found that the results differ very little from those obtained by Bethe in the second approximation. In the case of the simple cubic lattice the discontinuity of the specific heat is found to be only slightly larger than that obtained by Bethe.
