Exact solutions of nonlinear PDE, nonlinear transformations and reduction nonlinear PDE to a quadrature

摘要

A method to construct the exact solution of the PDE is presents, whichcombines the two kind methods(the nonlinear transformation and RQ(Reduction thePDE to a Quadrature problem) method).The nonlinear diffusion equation is chosento illustrate the method and the exact solutions are obtained.
