摘　　要：本文刻划了半格不可分的＞－弱幂ｐ－半群，描述了半格可分的２－弱幂ｐ－半群的结构．在此基础上，刻划了２－弱幂△－半群．This paper characterizes 2-weakly exponential P-scmigroups which are scmilattice indccomposable and describe the structure of 2-weakly exponential P-semigroups which are semilattice decomposable. From these, this paper proves that 2-weakly exponential Δ-semigroups are exactly weadly exponential Δ-semigroups. By using Nagy's result, this paper characterizes 2-weakly exponenhal Δ-semigroups.
