摘　　要：讨论一维双原子链在长波近似下的非线性振动特征 ,利用连续极限的方法 ,在只考虑最近邻相互作用的条件下 ,建立了一维双原子链的非线性振动方程 ,并通过求解该非线性振动方程 ,得到一维双原子链的非线性振动具有声学和光学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.
