  4. In the second section, we study the multiplicity of weak focus in system ( 1 ) when b = 0, then system ( 1 ) becomes : in [ 7 ], the authors show that system ( 2 ) has rich global dynamics depending on all parameters, including a weak focus with multiplicity at least 2, but the authors did n ' t calculate the multiplicity. in the second section of this article, we calculate the order of the weak focus with formative series method and mathematica 4. 0, and show that the order of the weak focus is two for some parameters. we also get the stability, then by hopf bifurcation theorem, we show that system ( 2 ) has at least two limit cycles for some parameters

    而且我們選擇了系統的原參數中的二個作為分支參數，可以使系統（ 1 ）進行bogdanov - takens余維2普適開折，從而證明系統（ 1 ）同宿軌的存在性。第二部分我們討論系統（ 1 ）當b = 0時細焦點的階數。當b = 0時，系統（ 1 ）為一文7對系統p ）進行了全參數分析得到系統）豐富的全局動力學性質，但當參數取某些值時系統間出現了階數大於或等於2的細焦點，文沒有計算該細焦點的階數。

  6. 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 ）附近的動力學性質帶來了困難，我們應用文獻[ 17 ]中關于研究非線性方程奇點的系列理論和方法，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的軌線趨于（ 0 ， 0 ）點的所有可能情況，其相圖也得以描繪；並且，系統不存在極限環的幾個充分條件我們也予以列出，當x的等傾線在0 x 1范圍內遞減時，系統不存在極限環，全局漸近穩定；然後，我們以中心流形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的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的焦點型平衡點，存在參數， m ，的值使得系統（ 6 . 1 ）有兩個極限環，還存在參數， m ，的另外值使得系統（ 6 . 1 ）有同宿軌或雙同宿軌。
