在早期的论文中，我们已经构建了差分方法，在空间和时间上都是四阶精度的波传播问题。分析和数值实验仅限于一维问题。在本文中，我们的建设和分析扩展到两个空间维，并提出了数值实验中的不连续介质中的声学问题。
In earlier papers we have constructed difference methods that are fourth-order accurate both in space and time for wave propagation problems. The analysis and numerical experiments have been limited to one-dimensional problems. In this paper we extend the construction and the analysis to two space dimensions, and present numerical experiments for acoustic problems in discontinuous media.
