The introduction of quark delocalization can be viewed as taking into account either the contribution of excited configurations or the distortion of individual baryon due to mutual interaction, its characteristic is to allow the six-quark system to choose the favorable configuration by its own dynamics automatically; Various quark models extended linear or quadratic confinement potential for 3q system to 6q system directly. Due to the nonlinearity of QCD, quark-quark interaction in color singlet may be different from that in non-color singlet. For example, the contribution of three-gluon exchange to one baryon is different from that to two baryon singlets, and so on.

引入夸克蜕定域效应，既可以看作是考虑了具有较高能量的激发组态的贡献，也可以看作是考虑了重子不碰撞过程中发生了畸变，其特点是让夸克体系自动选取最有利的组态；以往的QCD模型总是将哈密顿量直接从单重子系统推广到双重子系统，但QCD理论是一个非线性理论，处于色单态的两个夸克间的相互作用可能不同于处于非色单态的两夸克间的相互作用。
