采用离散载波与连续包络的解析方法求得了一维Klein-Gordon双原子晶格中的各种可能的传播非线性局域模.在系统振动频率与载波波矢全平面中不同区域内分别得到了脉冲包络和扭结(反扭结)包络传播非线性局域模.

All posible existed moving nonlinear localized modes for one-dimensional Klein-Gordon diatomic lattice are obtained analytically in the whole ω-q plane of the system by means of the so-called semidiscrete approximation,with which the carrier wave is treated explicitly while the enenlope is described in the continuum approximation.We found both pulse and kink(antikink) envelope moving vibrational modes for this lattice system can be occurred with certain carrier wavenumbers and frequencies in the separated regions of the ω-q plane.
