中文摘要：
考虑了一类噬菌体死亡率受到白噪声干扰的随机噬菌体-细菌模型.主要研究了边界平衡点的随机渐近稳定性和随机模型的解围绕相应确定性模型正平衡点的振荡行为,并通过数值仿真验证了所得理论结果的正确性.
英文摘要：
This paper investigates a stochastic phage-bacteria model in which the death rate of phage is influenced by noise.The stochastic asymptotical stability of the boundary equilibrium is studied.It shows that the solution of the stochastic model spirals around the positive equilibrium of the corresponding deterministic model.Finally,numerical simulations are presented to illustrated the theoretical results.
