文摘In this paper we consider a two-parameter perturbated system which takes the systems discussedin [1], [2], [3] as its special case. The bifurcation region of the limit cycles is given on theparameter plane. The author also studies the stability of the limit cycles. At the end of this paperthe author discusses the difference of the bifurcation of the limit cycles from a center between thecase of two-parameter and the case of one-parameter.
