摘要：
By virtue of the method of continuum limit, we obtained the solitons of the vibration of lattice in one-dimensional harmonic and anharmonic molecule chains, through which the equations of exciton and phonon are solved. On considering the cubic anharmonic potential, the vibration of lattice in one-dimensional molecule chain has a solution of kink soliton and on considering the quartic anharmonic potential, the vibration of lattice in one-dimensional molecule chain has a solution of breathers.
