We first introduce several kinds of effect algebras including the anti-BZ-effect algebras and the S-anti-BZ-effect algebras, and then prove that the set of anti-BZ sharp elements of S-anti-BZ-effect algebras is an orthomodular lattice.

• 提出了几种新的unsharp有效代数,例如anti-BZ-有效代数和S-anti-BZ-有效代数,并证明了S-anti-BZ-有效代数的sharp元集合具有标准量子结构性质;
