摘　　要：分析了一类在α-干扰素治疗过程中丙型肝炎病毒受抑制的数学模型的稳定性质,并考虑了时滞对系统稳定性的影响,得到了系统产生Hopf的条件.We have discussed the stability of a class of Hepatitis C Viral with inhibition due to infection mathematical model during interferon-α therapy. Delay effect on the stability of the model was investigated and the conditions for which the system caused Hop bifurcation was obtained.

关 键 词：丙型肝炎病毒 Α-干扰素 稳定性 时滞 HOPF分支
