刻画了五元Brandt半群生成簇B2的所有子簇。基于此特征，提供了一个算法，决定如果一个有限的一组身份定义，在B2，一个非线性生成的子品种。
All subvarieties of the variety B2 generated by the five-element Brandt semigroup are characterized. Based on this characterization, an algorithm is provided that decides if a finite set of identities defines, within B2, a finitely generated subvariety.
