AB - As a typical mathematical model in fluids and plasmas, Korteweg-de Vries  equation is famous. In this paper, the Exp-function method is extended to a  nonisos-pectral Korteweg-de Vries type equation with three variable  coefficients, and multi-wave solutions are obtained. It is shown that the  Expfunction method combined with appropriate ansatz may provide with a  straightforward, effective and alternative method for constructing multi-wave  solutions of variable-coefficient non-linear evolution equations.
