本文以 C_(70)H_(72)~(2+)双荷电孤子体系为模型计算了二荷电孤子相互接近时其间静电库论作用的变化情况,用以讨论掺杂程度不同时反式聚乙炔中荷电孤子间的静电库伦作用。计算结果表明,当杂质浓度超过4%以后.由于荷电孤子间静电库伦作用的明显增大,反式聚乙炔的导电态将由荷电孤子态向极化子态转变,解释了掺杂聚乙炔的奇特电、磁学性质。 In this paper, we take the C_ (70) H_ (72) ~ (2 +) double-charged soliton system as a model to calculate the change of electrostatic charge function between two charged solitons when they are close to each other, Electrostatic Coopern in Charged Polyacetylene. The calculated results show that when the impurity concentration exceeds 4%, the charge state of charged polyacetylene will change from the charged soliton state to the polar state due to the increase of electrostatic coulombs between charged solitons. The strange electricity, magnetic properties.
