Abstract: To construct infinite sequence peak solitary wave solutions to nonlinear evolution equations, Baicklund transformation of Riccati equation and nonlinear superposition formula of the solutions are introduced, then Degasperis - Procesi equation is taken as an example and infinite sequence peak solitary wave solutions and periodic solutions of the equation are obtained with the help of symbolic computation system Mathematica.
