摘要：

By using the bifurcation theory of planar dynamical systems and the method of detection functions, the bifurcations of limit cycles in a Z(2)-equivariant planar perturbed Hamiltonian polynomial vector fields of degree 7 are studied. An example of a special Z(2)-equivariant vector field having 50 limit cycles with a configuration of compound eyes are given.
