This paper set out from Holstein model of the quantization, by means of the method of incoherent state expansion, get the non-Linear Schrdinger equation of the polaron in ground state of one-dimensional molecular crystal, and get the soliton solution of fixed state,the ground state energy, the lattice displacement.
