本文讨论了有界域上一阶双曲型问题的误差增长问题。能量法被用来研究何时获得误差增长或固定误差界。结果表明，边界方法的选择是一个关键问题。数值实验验证了理论研究结果。
In this paper we address the error growth in time for hyperbolic problems in first order form in bounded domains. The energy method is used to study when an error growth or a fixed error bound is obtained. It is shown that the choice of boundary procedure is a crucial point. Numerical experiments corroborate the theoretical findings.
