| 摘 要： | 利用晶格动力学方法,研究在高压下几种导电高分子具有不同晶格链时的色散关系及其曲线的变化.链间耦合作用的减弱使横波与纵波的ω差值相应增大,且在BZ边界处拉开一个间隙,这是维度作用的结果.

| Abstract: | Using the classical mechanical method, the changes of the dispersion relation and curves of some conducting polymers with different crystal chain has been studied under high-pressure. The differences of ω between transverse wave and longitudinal wave increase with the decrease of coupling action, and the gaps are drawn at the boundary of BZ. This is dimensional effect. |
