摘要：

A projective cover in a category, K, of algebras is a morphism ϕ:P → A where A, P ∈ K, P is projective in K and no proper subalgebra of P has A as its direct image under ϕ. Projective covers of finite distributive lattices in the categories ℒ, of all lattices and ℒfinof all finite lattices are determined (when they exist). © 1979, University of California, Berkeley.
