通过分析未扰系统的首次积分函数沿扰动系统的轨线的增量 ,研究了一类平面系统的闭轨分支问题 ,获得了闭轨的存在性条件及稳定性准则 .
By analyzing the increment of the first integral function of the unperturbed system along the orbit of the perturbed system, the author studied the bifurcation problems of closed orbits for a class of planar system. The existence conditions of closed orbits and the stability criterion were obtained. At last, an example was given.
