摘　　要：艰难梭菌感染(clostridium difficile infection,CDI)是一个严重影响人类健康的疾病,而阑尾细菌可以在一定程度上抑制CDI的发生和感染.考虑了一类艰难梭菌感染的三维系统,用微分方程定性理论的知识分析系统平衡点的存在性和闭轨的不存在性.Clostridium difficile infection(CDI)is a serious disease threatening human health.Appendiceal bacteria can in some degree inhibit the occurrence and infection of CDI.Based on previous studies,a class of 3D CDI system is put under examination.The existence of system equilibrium and the nonexistence of closed orbit are both analyzed.

关 键 词：非线性动力学 平衡点 闭轨 CDI
