摘　　要：J.B.Fountain1977年定义了Crpp半群,利用半群S上的右Green同余关系,他给出了Crpp半群的一个定理。此文研究弱左Crpp半群,用已得到的左C完全Ehresmanncyber群的结构定理给出此类半群的一个结构定理。弱左C半群的结构定理是此定理的特例。The concept of C-rpp semigroup was first introuced by J. B. Fountain in 1977. By using a right Green congruence relationL^＊ which is a generalization of the usual Green L relation on a semigrop S, he gaves a theorem for C-rpp semigroups. The C-rpp semigroups to weakly left C-rpp semigroups is generalized and given a construction theorem for such semigroups by using the structure theorem of the left C-full Ehresmann cyber groups recently obtained by the authors. The structure theorem of weakly left C-semigroups is also includ, as its special case.
