研究了G=SU（3）的位形空间GN=G× G ×G关于G的作用用内自同构约化后的分层结构.这是一个从格点QCD发展而来的有限维模型。首先，分层的代数特征，任意N。接下来，讨论了N=1和N=2情况下的不变量的全代数。最后，对于N=1和N=2，分层结构进行了详细的研究，无论是在不变量和关系，并在更多的几何术语。此外，地层的特点是明确使用当地的横截面。
The stratified structure of the configuration space GN=G×⋯×G reduced with respect to the action of G by inner automorphisms is investigated for G=SU(3). This is a finite dimensional model coming from lattice QCD. First, the stratification is characterized algebraically, for arbitrary N. Next, the full algebra of invariants is discussed for the cases N=1 and N=2. Finally, for N=1 and N=2, the stratified structure is investigated in some detail, both in terms of invariants and relations and in more geometric terms. Moreover, the strata are characterized explicitly using local cross sections.
