摘要

本文采用有限差分时空法对 Korteweg-de Vries（KdV）和 Regularized Long Wave（RLW）方程进行了数值分析。KdV 和 RLW 方程是描述浅水长波行为的偏微分方程。我们证明有限差分时空法是数值求解这些方程的有效方法，并将其结果与使用显式方法和广义有限差分（GFD）公式求解的结果进行了比较。我们的结果表明，有限差分时空法为 KdV 和 RLW 方程提供了精确而稳定的解。

On the Comparison of Two Meshless Finite Difference Methods for Solving Shallow Water Equations

In this article, we present a numerical analysis of the Korteweg-de Vries (KdV) and Regularized Long Wave (RLW) equations using a finite difference space-time method. The KdV and RLW equations are partial differential equations that describe the behavior of long shallow water waves. We show that the finite difference space-time method is an effective way to solve these equations numerically, and we compare the results with those obtained using explicit method and generalized finite difference (GFD) formulae. Our results indicate that the finite difference space-time method provides accurate and stable solutions for both the KdV and RLW equations.
