The method of calculating the solitons which put forward by Kruskal and Zabusky has played an important role in the development of the soliton theory,however,numerous numerical results show that even though the parameters satisfy the linear stability,nonlinear instability will also appear.
Kruskal 和 Zabusky 提出的计算孤立子的方法在孤立子理论的发展过程中起了重要作用,但是大量的数值结果表明,即使在满足线性稳定性的参数条件下,该方法也会出现非线性不稳定性的数值现象。
