  2. Especially, when the isocline of x is monotone decreasing in 0 < x < 1, the svstem has no limit cycle and is globally stable ; next, we construct a saddle bifurcation at the boundary equilibrium and a degenerated bogdanov - takens bifurcation at the interior equilibrium by choosing appropriate parameter values in the following two sections, where our work are based on the theory of central manifolds and normal torms. we prove that is a codimention 3 focus - type equilibrium. system ( 6. 1 ) will have two limit cycles at some appropriate bifurcation parameter values, and have homoclinic or double - homoclinic orbits at some other appropriate bifurcation parameter values ; at last, we study the qualitative properties of the system at infinite in the poincare sphere

    因為系統在( 0 , 0 )點處沒有定義,這給研究其在( 0 , 0 )附動力學性質帶來了困難,我們應用文獻[ 17 ]中關于研究非性方程奇點系列理論和方法,圓滿解決了這一問題,給出了第一象限內當t +或t -時,在全參數狀態下系統趨于( 0 , 0 )點所有可能情況,其相圖也得以描繪;並且,系統不存在極限環幾個充分條件我們也予以列出,當x等傾在0 x 1范圍內遞減時,系統不存在極限環,全局穩定;然後,我們以中定理和正規型方法為主要工具,巧妙選擇參數,分別構造了一個余維2鞍點分岔和一個余維3退化bogdanov - takens分岔,證明了平衡點是余維3焦點型平衡點,存在參數, m ,值使得系統( 6 . 1 )有兩個極限環,還存在參數, m ,另外值使得系統( 6 . 1 )有同宿軌或雙同宿軌。
