设a2为五元非正统0-简单半群生成的变体。本文给出了a2的几个非完全0-简单半群或完全0-简单半群生成的子簇的恒等基。将会证明A2的几个亚种，包括由五元Brandt半群产生的品种，是遗传有限基的。
Let A2be the variety generated by the five-element non-orthodox 0-simple semigroup. This paper presents the identity bases for several subvarieties of A2that are not generated by any completely 0-simple or completely simple semigroups. It will be shown that several subvarieties of A2, including the variety generated by the five-element Brandt semigroup, are hereditarily finitely based.
