利用一个与质量有关的重正化方案，研究了O（N）模型破缺相的红外重正化群性质．得到了与质量有关的一圈重正化群系数以及在红外极限下的二圈重正化群系数．利用标准的微扰场论计算方法，发现特殊的抵消效应，该效应使得二圈的重正化群系数与一圈重正化群系数在红外极限下相同． A qualitative renormalization scheme was used to study the properties of infrared renormalized groups in the broken phase of the O (N) model. The quality-related one-pass renormalization group coefficients and the two-turn renormalization group coefficients at the infrared limit are obtained. Using standard perturbation field calculations, special cancellation effects are found that cause the two renormalization group coefficients to be identical to one renormalization group coefficient at the infrared limit.
