Using the formula of the nearly local pair model , based on the two - component model of high - 以基于高溫超導體雙成分模型的近局域對理論分析bi
In two - component model of hydrogen - bonded chains , the system with nonlinear and linear coupling between proton sublattice and heavy - ion sublattice is investigated . fast - mode soliton pair and slow - mode soliton pair are obtained . as for fast - mode soliton the effective mass of the kink in the proton sublattice decreases due to the nonlinear coupling and increases due to the linear coupling . for slow - mode soliton , the thing is quite opposite to that of fast - mode soliton 在氫鍵鏈二分量模型中,研究質子子晶格和重離子子晶格相互作用項中同時含有非線性耦合和線性耦合兩部分的系統(tǒng),得到快模孤子偶和慢模孤子偶.對于慢模孤子而言,非線性耦合降低了質子子晶格中孤子的有效質量,而線性耦合增加了質子子晶格中孤子的有效質量;對于快模孤子而言,情況正好相反
