本文用拟正规扇区的方法研究了轨道在退化奇点处的定性行为,这是Frommer正规扇区的推广。实例表明,该方法比众所周知的z -扇区、正规扇区和广义正规扇区方法更有效。
This paper deals with the qualitative behavior of orbits at degenerate singular point with the method of quasi normal sector, which is a generalization of Frommer’s normal sectors. Several examples show that this method is more effective than the well-known methods ofZ-sectors, normal sectors and generalized normal sector.
