中文摘要：
首先给出一类具有相互干扰的两种群捕食系统．分析了其解的有界性及正平衡点的存在性,证明了正平衡点是全局渐近稳定的．且系统在破内不存在极限环．并通过数值模拟验证了结论的正确性，最后简单地讨论了连续收获效应对系统的影响．
英文摘要：
A kind of predator-prey system with mutual interference is presented firstly, then the boundedness of the solution and the existence of positive equilibrium are analysized. It is proved that positive equilibrium is globally aympotically stable and that the system has no limit cycle in R^2. Furthermore numerical stimulation verifes the results obtained in this paper. Finally,the effects of continuous harvest on the system is discussed tersely.
