重新计算了标准模型中的双圈重整化群方程。在四次耦合的β函数中发现了一个新的系数，并发现在强子Yukawa耦合的β函数中缺少一类规范不变量。给出了希格斯质量参数的双圈β函数的完整形式。
Two-loop renormalization group equations in the standard model are recalculated. A new coefficient is found in the beta function of the quartic coupling and a class of gauge invariants is found to be absent in the beta functions of hadronic Yukawa couplings. The two-loop beta function of the Higgs mass parameter is presented in complete form.
