【摘要】 构建一类合成毒品滥用者接受治疗前后的传染性模型。研究表明:当R₀ <1时,时滞τ不影响无合成毒品滥用平衡点E₀的稳定性;当R₀>1时,合成毒品传播平衡点E^*产生纯虚根条件。数值模拟验证了此结论。更多还原

【Abstract】 To model a class of synthetic drug abusers as infectious before and after treatment,Studies have shown that when R₀ <1,the time delayτdoes not affect the stability of equilibrium point E₀ without synthetic drug abuse,and when R₀ >1,the conditions for the production of pure imaginary roots of equilibrium point E^* with synthetic drug propagation,The results are verified by numerical simulation.更多还原
