摘要
贩毒吸毒是人类丑恶行为表现出的社会丑恶现象,在人类正常的生活环境中时有发生。特别近年来有的国家或地区呈现流行的趋势,各国对此都十分关注。建立三个描述贩毒吸毒社会丑恶现象的微分方程模型。借助于微分方程定性论的基本理论,分析微分方程模型基本理论,分析贩毒吸毒流行的趋势,流行的结局,得到基本符合实际的效果。
This paper gave three models of differential eqations for represent social bad phenomena of sell poison and absorb poison. Through qualitative analysis of differential equations, We can grasp the current of sell poison and absorb poison and the end of current. We obtain the results suit well with practice fundamentally.
