摘要：

This note clarifies the confusion in the transformation that transforms the advection-dispersion equation with time-dependent coefficients into the advection-dispersion equation with constant coefficients. It is proved that the analytical solutions based on this transformation cannot satisfy the advection-dispersion equation with time-dependent coefficients.
