Toda晶格中的激波与孤立波

Shock wave and solitary wave in Toda lattice

数值计算结果表明，Ｔｏｄａ晶格中激波速度是活塞速度的２倍；给出了粒子运动速度的单孤立波表达式。

The single solitary wave formula is given for the particle velocity in Toda lattice,the velocity of shock wave is twice of that of solitary wave.The relationship between the shock wave U s and the piston velocity U p are also given.
