摘要
本文对相互作用势含有六阶非线性项的一维晶体振动分别用连续介质近似方法和声子相干态的量子化方法导出了所满足的波动方程,并就某些参数条件求出了稳定孤立波解.
The wave equatior of lattice oscieeation is obtained for a one-dimens -ional anharmonic lattice where the sixth order anharmonicity in the potential is taken by the classical continuum approximation method and the phonon coherent state method, respectively. The possible solitary wave solutions are discussed.
