Abstract Transformation plays a significant role in solving hydrological problems. In response to the comment on Singh and Das (2015) by Deng et al. (2015) regarding the transformation, boundary conditions and subsequent analytical solution of advection dispersion equation in semi-infinite heterogeneous porous media, it is argued that the transformation used by Singh and Das (2015) for finding the analytical solution is correct and mathematically valid. Also, the different expression of f ( mt ) used to obtain the solution are explained with their physical relevance in the field.

对“非均质介质中具有线性等温线的尺度相关溶质分散（Journal of Hydrology 520 (2015) 289-299)”论文的评论

摘要 变换在解决水文问题中具有重要作用。为了回应 Deng 等人对 Singh 和 Das (2015) 的评论。(2015) 关于半无限非均质多孔介质中平流色散方程的变换、边界条件和后续解析解，认为 Singh 和 Das (2015) 用于寻找解析解的变换是正确的，并且在数学上是有效的。此外，还解释了用于获得解的 f ( mt ) 的不同表达式及其在该领域的物理相关性。
