【Abstract】 By virtue of the method of continuum limit, we obtained the solitons of the vibration of lattice in one-dimensional monoatomic chains, through that the equations of nonlinear vibration of one-dimensional monoatomic chains are solved. Under considering cubic anharmonic potential , the vibration of lattice in one-dimensional monoatomic chain have solution of kink soliton and under considering quartic anhannonic potential, the vibration of lattice in one-dimensional monoatomic chain have solution of breathers.更多还原
