用非标准形式的色散项考虑各种色散模型的驻波解。利用指数计数计算，结合变分结构的信息，我们开发了这些波的谱稳定性的尖锐条件。
We consider standing wave solutions of various dispersive models with non-standard form of the dispersion terms. Using index count calculations, together with the information from a variational construction, we develop sharp conditions for spectral stability of these waves.
