  In this paper, we use the homogeneous balance(HB) method is used to construct
function transformation to solve the nonlinear development
equation||Fisher-Kolomogror-Pertrovskii-Piskmov equation (FKPP equation), then
the exact solution of FKPP equation is obtained, and the solutionis converted
into the form of isolated wave solution. Finally, we have shown the solution of
FKPPequation in some picture forms, and the rationality of the solution in this
paper can be verified byusing the pictures.
