| 摘 要： | 从包含电子－电子相互作用和外库仑势的ＳＳＨ推广模型出发，计算了在各个掺杂浓度（杂质等距离分布）下反式聚乙炔中孤子晶格周围的局域振动模。计算结果表明：在掺杂浓度为１．６７％时，反式聚乙炔存在１０个局域模；在浓度为３．３３％～１０．００％时，存在８个局域模；而在浓度大于１３．３３％时，所有的局域模都消失变为扩展模。

| Abstract: | From the extended SSH model that includes an external Coulomb potential arising from interchain charged solitons and counterions,the interchain e-e interaction and the SSH Hamiltonian,the localized vibrational modes around soliton lattice are calculated at all dopping levels from 1.67 at.% to 13.33 at.%。 |
