The Topological Classification of Plane Phase Diagram of\=a Class |of Quintic Hamiltonian System
一类五次Hamilton系统平面相图的拓扑分类

This paper studies a class of quintic Hamiltonian system. By analysising and calculating the coefficients of the system, we obtain all topological types of the phase portraits to the system, which will be useful to study its perturbed system later.
