| 摘 要： | 对非线性叠加效应进行了研究,在Toda晶格中,当两孤立子运动方向相同时,其速度波的振幅的极大值是原来两波振幅之差,两波叠加的最大振幅是原来两波振幅之和。这些结果跟线性波叠加情况是完全不同的。

| Abstract: | The diference between linear wave and nonlinear wave is studied.The interaction of two nonlinear waves in Toda lattice is given numerically.When the two nonlinear waves propagate in the same direction,the maximum amplitude is equal to the difference of the am- plitude of the two waves.When the two nonlinear waves propagate in opposite direction,the maximum amplitude is just equal to the plus of the amplitude of the two waves. |
