Generalized Boolean quasirings are ring-like structures used as algebraic models in the foundations of axiomatic quantum mechanics. The quantum mechanical system corresponding to such a quasiring turns out to be a classical one if and only if this quasiring is a Boolean ring with unit. We characterize this situation by a single identity.

广义布尔拟定何时何时成为布尔环？

广义布尔拟态是在公理量子力学基础上用作代数模型的环状结构。当且仅当该准定是一个带单位的布尔环时，与这种准定对应的量子力学系统才证明是经典系统。我们通过单一身份来描述这种情况。
