| 摘 要： | 为了定性地研究微分方程系统，通常要讨论中心－焦点问题。本文讨论了一类Ｌｉｅｎａｒｄ系统，通过证明定理，指出连续奇，偶次这类系统在原点具有不同的拓扑结构（即相连奇，偶次系统不能同时为中心），以便于进一步求得该系统的焦点量上界问题。

| Abstract: | We often discuss the centre-focus's problem to study the system of ordinary differential equations. This paper discusses a class of Lienard system. By proving theorem.it points out continuous odd and even system with different topological structure(the next odd and even system can't both be centre).This is the base to better solve the systematic focus's quantity upper bound. |
