对于± J-Ising模型，证明了当模型A由模型B通过添加键得到时，模型A中多临界点的pc（+ J键浓度）不超过模型B中的pc（pc，A ≤ pc，B），其中每个键都以与模型B中相同的概率权取+ J或- J.证明适用于任何晶格结构、晶格维数和相互作用范围。
For the ± J Ising models, it is proved that p c (the concentration of + J bonds) of the multicritical point in the model A does not exceed that in the model B ( p c,A ≤ p c,B ) when the model A is obtained from the model B by adding bonds, each of which takes + J or - J with the same probability weight as in the model B. The proof holds for any lattice structure, dimension of the lattice and range of the interactions.
