氢键系统中原子间非谐相互作用下的扭结

KINKS IN HYDROGEN-BONDED SYSTEMS WITHIN THE ANHARMONIC INTERATOMIC INTERACTIONS

用微扰方法研究了氢键系统中在非谐相互作用近似下的扭结孤子，给出了３次方到６次方非谐项下的扭结与反扭结的非对称解，计算了由非谐项引起的扭结孤子的有效质量。

Using the perturbation method,we study the kinks in hydrogen-bonded systems with anharmonic interatomic interaction approximation, obtain the asymmetric solutions of kink-antikink from the cubic to the sixth power of the anharmonicity,and calculate the effective mass of the kinks due to the anharmonicity.
