在反常关系的基础上重新审视了强相互作用中的CP破坏，重点强调了QCD真空的非平凡性。结果表明，在适当定义常规真空后，QCD 拉格朗日中的 CP 破坏相位受到反常关系的约束。如果重夸克之一具有消失的动力凝聚体，则提出了强CP问题的一种可能解决方案。
CP violation in strong interactions is re-examined on the basis of the anomaly relation with emphasis on the non-triviality of QCD vacuum. It is shown that after appropriately defining the conventional vacuum, the CP violating phases in QCD Lagrangian are subject to constraints derived from the anomaly relation. A possible solution to the strong CP problem is suggested provided that one of heavy quarks has a vanishing dynamical condensate.
