摘　　要：本文运用线性算子的谱理论和Lyapunov-Schmidt约化方法,研究了一类Neumann边界条件下的带有扩散项的病毒模型的定态分歧方程,然后计算出当系统参数λ大于临界参数时,模型会发生分歧现象.In this paper,the stationary bifurcation of a virus model with diffusion term under Neumann boundary conditions is studied.The bifurcation equation of the model is obtained by the spectral theory of linear operators and Lyapunov-Schmidt reduction method,and then the bifurcation phenomenon of the model is calculated when the system parameters are larger than the critical parameters.
