本文用QCD求和规则研究了和四夸克态，得到了与实验数据相符合的预言、、和。进一步说明了双夸克-反双夸克型四夸克态可以看作是一系列介子-介子对的特殊叠加，它体现了净效应。
In this article, we study theandtetraquark states with the QCD sum rules, and we obtain the predictions,,and, which can be confronted to the experimental data in the future. Furthermore, we illustrate that the diquark–antidiquark type tetraquark state can be taken as a special superposition of a series of meson–meson pairs and that it embodies the net effects.
