摘要: 用平面动力系统定性分析方法和数学软件Mathematica对五次代数曲线的图形进行分类.首先建立一个与这类代数曲线相对应的平面动力系统,然后研究奇点的分布及性质,找出参数平面的分支曲线,再用Mathematica画出了代数曲线的图形,并完成了图形的分类,将这一类代数曲线的图分为了l2类.

Abstract:
The graph classification for a class of quintic algebra curves is carried out by means of the software Mathe-matica and the qualitative analysis method of planar dynamical system.In the classification,first,a planar dynami-cal system corresponding to the quintic algebra curves is constructed.Next,the distributions and properties of sin-gular points are studied.Then,the bifurcation curves are given on the parametric plane.Finally,the graphs of the algebral curves are drawn by using the software Mathematica.Thus,the classification is completed,dividing the graphs into twelve types.
Key words: quintic algebra curve, mathematical model, graph classification, planar dynamical system, qualitative analysis, mathematical software
