构造了非阿贝尔规范理论中的规范变换对A (x)， A' (x)的例子，其中(1)都在库仑规范中，(2)都具有零拓扑电荷，(3)在大r时都以大于1/r的速度下降，因此出现在紧化理论中。这些例子说明了这样一个事实，即格里波夫歧义包含的现象比用瞬子描述的多得多。
Examples of gauge transform pairs of fields A (x), A' (x) in non-Abelian gauge theories are constructed in which (1) both are in the Coulomb gauge, (2) both have zero topological charge, (3) both fall faster than 1/r at large r, and therefore occur in the compactified theory. These examples illustrate the fact that the Gribov ambiguity encompasses a larger variety of phenomena than those described by instantons.
