Using the homotopic theory, an approximate solution for a class of nonlinear pro blems is first discussed.Then,the precision is raised by using variational inter active methods.Finally, a combustion model is applied and the approximate soluti on is obtained.

We present a field method for solving the Whittaker equations.One of the field variables is considered as a function of other variables and time,and the fundamental partial differential equation for the function is established.If the complete integral of the partial differential equation can be obtained,the solution of the Whittaker equations are obtained by solving the algebraic equations.
