摘　　要：特征线法是把不稳定流问题的两个偏微分方程,用两个特征值,转换成四个长微分方程,然后使用显示差分法把常微分方程表示成差分方程,在计算机上求解的一种方法,文章结合具体算例,采用特征线法用MATLAB进行编程计算。结果表明,这种方法计算速度快,收敛性好是一种很有效的计算方法。The characteristic line method is the unsteady flow problems of two partial differential equations, values for two features, converted into four long differential equation, and then using differential display method to ordinary differential equations into difference equations, in computer to solve a method, the paper detailed examples, with the characteristic line method with MATLAB programming. The results show that this method is fast and effective.
