| 摘 要： | 基于对氢键分子系统中质子激发和移动的特点的仔细分析，提出一个新的哈密顿函数和理论，用以研究由质子位移所导致的质子的局域性涨落和重离子子晶格的构象畸变而引起的质子的集体激发和质子传递的特性，给出了运动方程和相应的孤立子解，讨论了这些解的特征

| Abstract: | Based on the analysis of properties of protonic excitation and displacements in the hydrogen bonded molecular systems we proposed here a new model Hamiltonian and theory for studying the properties of nonlinear collective excitation and proton transfer resulting from the localized fluctuation of protons and the deformation of structure of heavy ionic sublattice owing to the protonic displacements.We give the equations of motion and corresponding solutions of solitons,discuss the features and meanings of these solutions and the advantages of our model,and explain completely motion of two kinds of defects and proton transfer in the hydrogen bonded molecular systems. |
