摘要：

This paper considers the lattice of subquasivarieties of a regular variety. In particular we show that if V is a strongly irregular variety that is minimal as a quasivariety. then the smallest quasivariety containing both V and Sl (the variety of semilattices) is never equal to the regularization (V) over tilde of V. We use this result to describe the lattice of subquasivarieties of (V) over tilde in several special but quite common, cases and give a number of applications and examples.
