摘　　要：为了对全国平均每百户居民私家车拥有量进行预测,建立了可分离变量微分方程的数学模型,采用最小二乘法,借助Excel作为计算工具,得到了微分方程近似解的参数值,并用微分方程的近似解估计了最大拥有量以及2010年以后某些年的拥有量.In this paper a differential equation with separable variables is set up to model the dynamics of private car ownership in every hundred households in China. Parameters in the model are estimated by means of the least square method, and the prediction is then obtained by making use of the solution of the differential equation.
