摘　　要：采用集合坐标方法,运用新的二分量孤子模型,研究氢键系统中孤子偶与杂质的相互作用,得出在杂质区孤子偶的运动方程和入射速度的一般表达式,并进一步讨论在吸引型与排斥型两类不同杂质情况下孤子偶的运动特性.Using the collective coordinate method, we investigated the interaction between soliton pairs and impurities in hydrogen bonded systems, based on a new two-component soliton model. We obtained the experssions of the equations of motion and the velocity of the soliton pair in regions of impurities, and discussed further the motion of the soliton pair in regions of an attraction-type impurity and repulsion-type impurity.
