| 摘 要： | 对生物一类传染病模型dx/dt=ax+by+p(x,y),dy/dt=Q(x,y)(ab≠0)的平衡点(0,0)给出了直接判别定理,比现成的定理简捷些。并给出实例,对两种判别法的简捷程度作了比较。

| Abstract: | This paper gives a direct criterion theorem to the equilibrium (0,0) of the mathematic model of a class of biological infection dx/dt=ax+by+P (x,y), dy/dt=Q(x,y)(ab≠0). The theorem is simpler than the present one. We also provide examples to compare the simple degree of the two criterion. |
