摘要：

In this note, we prove that the quadratic system having a parabola as its integralcurve has at most one limit cycle, and therefore the quadratic system havingquadratic curve as its integral curve has at most one limjt cycle. Considering Ref.[1], we have solved completely the problem of the bifurcations of limit cycle forsystem (1).
