摘要：

Bifurcation of limit cycles from the class Q(3)(NH) of quadratic systems possessing centers is investigated. Bifurcation diagrams for various systems in this class are constructed, and are used to locate systems possessing a period annulus whose closure has cyclicity three. (C) 1995 Academic Press, Inc.
