摘要
在具余维２奇点的四维系统的两参数开折的研究中出现一类三点异宿环的扰动分支，对此异宿环产生极限环的唯一性一直未得到完整的解决，本文圆满地解决了这一问题。
In the study of 2\|parameter unfoldings of a 4\|dimensional system with 2 singularities one needs to investigate limit cycle bifurcations near a heteroclinic cycle with 3 vertices.The uniqueness of limit cycles has not been solved completely up to now.This problem is solved in the present paper,and the uniqueness of limit cycles is proved in the global bifurcation as well.
