本文指出，在参数间有一定关系的条件下，二元合金中晶体对称性发生变化的二级相变点处的热力学量的奇异性与伊辛模型中的奇异性是同一类型的，而伊辛模型中的奇异性已有若干结果可供计算机计算。参数显示，随后的条款不改变这些结果。玻色气体中的相变被发现是等效的平面偶极子晶格中的过渡。
It is shown that, subject to certain relations between the parameters, the singularities in the thermodynamic quantities at a second-order tran~ition point in a binary alloy, at which there is a change in the crystal symmetry, are of 1he same type as in the Ising model, for which a number of results are known from computer calculations. Arguments are presented to show that subsequent terms do not alter these results. A phase transition in a Bose gas is found to be equivalent to a transition in a lattice of plane dipoles.
