It is demonstrated by our numerical experiments that the wavy numerical errors, which are produced when the inviscid Burgers equation is solved by the particle method, are solitons. The error introduced by the Gaussian cored particle method is of the order of the third derivative which works as the dispersion term. As a result, the solitons are created. An empirical equation of the relation between the amplitude of the soliton and the dispersion error is obtained. This equation enables us to solve the K-dV equation. The relation between the diffusion term of the Burgers equation and the dispersion error is also studied.
