摘要
研究了具有双时滞二维捕食系统平衡点的稳定性问题,得到了该模型的稳定性条件和无条件稳定域,从而彻底解决了该模型的稳性问题。
The conditions for asymptotic stability properties of an equilibrium point of 2-dimension prey-predator model with two time-lag are studied. The conditional and unconditional demains of the prey-predator model are obtained. Therefore, the stability problem of the prey-predator model are solved.
