可重复感染的肺结核传播模型

摘要

By index input and standard incidence rate,an epidemic model of tuberculosis repeated infection with inoculation disease was established.The disease-free equilibrium was obtained,and the disease-free e-quilibrium point of the local and global stability was studied.Numerical simulation results further verified the correctness of theoretical results.%对于具有可接种且可重复感染的肺结核疾病，采用指数输入与标准发生率建立了传播模型，得到了无病平衡点，并研究了无病平衡点的局部以及全局稳定性。数值模拟验证了理论结果的正确性。
