格点费米子的交错形式在非对易几何中可以转化为直积K圈的形式。我们证明了这种交错的K-圈之间的对应关系和规范定义的K-圈的一个特殊情况下，格出现在一个生成的阿贝尔群。
Staggered formalism of lattice fermion can be cast into a form of direct product K-cycle in noncommutative geometry. We prove the correspondence between this staggered K-cycle and a canonically defined K-cycle for finitely generated Abelian groups where a lattice appears as a special case.
