摘要：
Lienard systems of the form x + Ef(x)x + x = 0, with f(x) an even continuous function, are considered. The bifurcation curves of limit cycles are calculated exactly in the weak (epsilon --> 0) and in the strongly (epsilon --> infinity) nonlinear regime in some examples. The number of limit cycles does not increase when epsilon increases from zero to infinity in all the cases analyzed.
