二维以上的仿射变体的结构可以借助仿射线或仿射平面的颤振和作用态的商构射来研究。我们考虑仿射三叠上的作用，讨论了商表面的结构和奇异性，以及商态射的奇异纤维。
The structures of affine varieties of dimension greater than two can be explored with the help of fibrations by the affine line or plane and quotient morphisms by-actions. We consider-actions on affine threefolds and discuss the structure and the singularities of the quotient surface as well as the singular fibers of the quotient morphism.
