摘要: 对泥沙反应扩散广义初边值问题,采用Laplace变换和复变函数中的Jordan引理,导出了一种解析解,它可作为Kwokming James Cheng的解析解形式的推广(对应于本文中r=0的解析解形式),并分析了利用解析解求解过程中的若干问题。

Abstract: The sediment reaction and diffusion equation with generalized initial and boundary condition is studied.By using Laplace transform and Jordan lemma,an analytical solution is got,which is an extension of analytical solution provided by Cheng Kwokming James(only diffusion was considered in analytical solution of Cheng).Some problems arisen in the computation of analytical solution formula are also analysed.
