摘要: 引入了一个新的模型来描述蛋白质分子中Amide-Ⅰ振动能量的贮存与传输。这种模型是在Davydov模型的基础上加以改进,引入激子的相互作用项。并用数值模拟的方法说明了该模型可以存在静止和运动的局域模式。

Abstract: A model is proposed to study numerically the dynamics for the energy transportion of amide Ⅰ vibrations in proteins.The results show that there exists static and moving localized models in the mode and thus it may provides alternative mechanism of the energy transport in protein molecules.

Key words: soliton, exciton, protein molecule, discrete nonlinear function
