| Abstract: | Investigate the characters of the nonlinear vibration of one-dimensional diatomic chains with the approach of long-wavelength.By virtue of the method of cintinuum limit,established the nonlinear vibration equation of one-dimensonal diatomic chains under considering nearest-neighbor interaction,and obatined the phononic and photonic kink-solitons of the nonlinear vibration in one-dimensional diatomic chains through that the equations are solved. |

| Keywords: | one-dimensional diatomic chain the approach of long-wavelength kink-soliton |
