摘要
本文从生物学角度出发,根据微分方程理论.结合给定的数据,经过合理的假设,建立了血液中酒精的浓度随时间变化的基础模型。并针对不同的饮酒方式和饮酒量,分别建立了相应的模型。用拟合的方法确定参数,准确地模拟出酒精浓度变化趋势的曲线,拟合结果与原始数据吻合程度较高。同时,对一些实际问题也给出了合理的解释。
According to the theory of differential equation, A basic mathematical model about the relation of alcohol in body and time is presented; Some models about practical problems are also given by using the basic model. What we find is fit for the given data perfectly, and some practical problems are answered finally.
