The underlying method is based on the simple wave solutions of a system of hyperbolic partial differential equations. 基本的方法是以双曲型偏微分方程组的简单波解为根据的。
In this paper, the estimate and uniqueness and stability of the solution of one-order hyperbolic differential equation of Cauchy Problem is proved. 摘要本文证明了双曲型方程组柯西问题解的估计，唯一性，稳定性。
