摘    要：应用量子作用角变量等方法证明了量子反铁磁体模型与O(3)非线性σ模型有相等性,并由此相等性,得出有关量子反铁磁体模型的几个重要推论.

Abstract: Using such method as the angle variable of quantum function, the author of this thesis proves that the models of quantum antiferromagnets and O(3) non-linear σ are equal and from this equality, draws several important inferences about the model of quantum antiferromagnets.
