摘　　要：本文定义Ehresmann型rpp半群,它是纯正群并在rpp半群类中的推广,我们给出了此类半群的最小C-rpp半群同余.It is well known that orthogroups are important semigroups in the class of regular semigroups. We now introduce the class of Ehresmann-typed rpp semigroups in the class of rpp semigroups. They are analogues of orthogroups in the class of rpp semigroups. The least C-rpp semigroup congruence on Ehresmann-typed rpp semigroups is given.
