摘要
对Toda晶格中单孤立波的粒子运动速度、位移及相邻粒子的相对位移进行了详细的讨论,从而得到了其间的联系,得出了单孤立波的动能及势能的表达式。当孤立波较弱时,势能大于动能;当孤立波较强时,动能大于势能。
The relationship between velocity and displacement in the Toda lattice and the relationship between potential and kinetic energy in Tcda lattice have been obtained. If the solitary wave is weak, the potential energy is bigger than kinetic energy. If the solitary wave is not weak, the result is contrary.
