本文对Ginsparg-Wilson关系中R进入手征对称破缺部分时，Ginsparg-Wilson费米子算符D的轴反常作了一般性的讨论。D的轴反常和指数以及Atiyah-Singer指数定理在格上的精确实现完全由手征极限R→0的手征对称算子D的拓扑特征决定。
The axial anomaly of Ginsparg-Wilson fermion operator D is discussed in general for the operator R which enters the chiral symmetry breaking part in the Ginsparg-Wilson relation. The axial anomaly and the index of D as well as the exact realization of the Atiyah-Singer index theorem on the lattice are determined solely by the topological characteristics of the chirally symmetric operator Dcin the chiral limit R→0.
