摘要
给出了一维Toda晶格中单孤立波自由反射的数值计算结果.结果表明,当孤立波的传播接近自由面时,有反射波从自由面处反射回来,自由面处粒子最大速度达到孤立波速度波峰的2倍,自由面处粒子位移由最初的一a变到最后的+a,反射波的传播速度与原孤立波完全相同.
The numerical solution of soliton reflection at a free boundary in Toda lattice is given in this paper. The reflection wave from free boundary is just same as original partical speed soliton. The partical speed at free boundary can be 2 times of amplitude of partical speed soliton when it reach its maximum velocity.
