从立方型相互作用的一维分子晶体模型出发,在加入本征值平方项的近似下,运用能量极小原理和连续化近似,得到了考虑本征值平方项和立方型相互作用后一维分子晶体模型的孤子激发的修正解.在忽略了立方型相互作用和本征值平方项的近似下,孤子激发的修正解回复于通常的极化子解.并计算了孤子激发的峰宽、峰值和电子自陷势阱,分析了本征值平方项和立方型相互作用对孤子激发的峰值、峰宽和电子自陷势阱的影响.
Starting from the one-dimensional molecular crystal model of cubic interaction, with the addition of the squared term of eigenvalue, using the energy minimization principle and the continuous approximation, we obtain the one-dimensional Solving the soliton excitation of the molecular crystal model, the correction solution of the soliton excitation is restored to the usual one by neglecting the cubic interaction and the squared eigenvalue. The peak width of the soliton excitation is calculated, Peak and electron trapping potential well, the influence of the eigenvalue squared term and the cubic interaction on the soliton excitation peak width, peak width and electron trapping potential well are analyzed.
