Only quark model is more successful for strong interaction, especially the experiment fact of the quantum chromo dynamics which is the basic theories of quark interaction, the strong interaction become one basic problem in physics again. 唯有夸克模型对于强相互作用却比较成功,特别是夸克相互作用的基本理论&量子色动力学(QCD)(QCD)的实验证实,强相互作用再次成为物理学中一个基本的问题。
