【摘要】 本文在较宽的条件下，对含多个奇点的Lienard型系统x＝h（y）-F（x），y＝-g（x）解的振动性进行了研究，给出了解振动的充要条件，推广和改进了文［1～4］的结果．更多还原

【Abstract】 In this paper,a necessary and sufficient condition for the solution of Lienardtype system with multiple sinsular points to oscillation under the more generalassumption is given. Results of papers [1-4] are also extended and improved inthis paper.更多还原
