一类三维动力系统周期轨道的存在性

Existence of Periodic Orbits of Class One Three--Dimensional Dynamic System

描述了一类三维动力系统，把二维动力系统的周期轨道的存在性、唯一性和稳定性的结论推广到了三维动力系统．

The paper discribes the class one three--dimensional dynamic system and spreads the conclusion of the existence, uniqueness and stability deduced from the two- dimensional autonomous system's periodic orbits to three--dimentional autonomous system.
