On the basis of the two-component soliton vibrator model,the motion of a kink pair consisting of kinks in different sublattices and soliton for the response of the external field are discussed.The mobility of a soliton pair is found.

• 以二分量孤子的振子模型为基础，讨论了质子子晶格与重离子子晶格中扭结孤子形成的孤子对的运动及其孤子对外场的响应特性；并得到了氢键链中孤子对的迁移率表达式.
