摘要
基于家禽饲养的实际,研究了具有常数输入且输入者中含有潜伏期者,同时染病者被隔离的SEQS模型.利用广义Bendixson-Dulac定理排除了周期解的存在,证明了有病平衡点一旦存在即是全局稳定的.
Based on actual poultry feeding,an SEQS epidemic model was constructed and analyzed,which contained constant immigration and latent period individuals in immigration,and infected patients were isolated immediately.According to general Bendixson-Dulac theorem,the existence of periodic trajectory was excluded,and it was proved that the unique disease equilibrium was globally stable.
