摘要
应用Lyapunov量复算法判定两类系统的奇点类型.采用Maple数学软件,根据Lyapunov量复算法计算两类系统的Lyapunov量,得出系统一中原点的最高阶细焦点阶数为1及原点是一不稳定细焦点,判定出系统二的实奇点类型,得出系统二中原点是中心.
The application of Lyapunov double calculation method is mainly used to judge the types of singularities of two types of systems.With the aid of mathematical software Maple applying Lyapunov double calculation method under a certain program to calculate the amount of Lyapunov of two classes of systems,which can conclude that origin of the highest order fine focusnumber is 1and the originis an unstable fine focus in system one,also identify thereal point type in system two,and the origin in system two is the center.
