If Ф preserves commutative zero-products and Ф(FP)■FФ(P) and Ф(P)≠0 for every rank one idempotent operator P∈A,Then it has one of the following forms:an algebraic isomorphism,a conjugate algebraic isomor-phism,an algebraic anti-isomorphism and a conjugate algebraic anti-isomorphism.

若Ф保交换零积并且对所有的一秩幂等算子P∈A都有Ф(FP)FФ(P)和成立。
