具有一类新型分界线环的二次系统的第一个例子

A First Example of Quadratic System with a New Type Separatrix Cycle

通过一个例子,证实了一种求多项式系统当参数变化时极限环消失的分支值新的方法是可行的.

This paper through an example verified that a new method of searching the bifurcation of the disappearance of limit cycle with the variation of the parameter in a quadratic system is feasible.
