摘要
研究了一类非线性系统极限环唯一性问题，所获得结果允许系统具有多个奇点，推广和改进了一些现有的关于此类系统的唯一性结果．
In this paper,the uniqueness of limit cycles is investigated for the nonlinear system and some new results are obtained. These results hold for the system with multiple singular points. Some other known results concerning the above system are generalized and improved.
