在点态化完备代数正规类中引入预根、拟根概念，证明了代数类中的幂等拟根与Amitsur-Kurosh根类可以相互确定，从而代数类中的幂等拟根P是Amitsur-Kurosh根类的基于映射刻画。 In this paper, the concepts of preradical and quasiradical in the normal classes of pointwise com-plete algebras are defined. It is proved that the idempotent quasiradicals and Amitsur-Kurosh radicals in algebraic classes can be determined by each other. Thus, idemquasiradicals P in alge-braic classes are the mapping based characterization of Amitsur-Kurosh radicals.
