摘要： 本文应用正则长波方程来研究由边界脉冲产生的孤立波解。对正则长波方程给出一个守恒差分格式,通过这个格式数值地算出各种边界脉冲产生的孤立波解。初步地得到了在所产生的孤立波的振幅和数目与边界脉冲之间的关系,比较了边界脉冲产生的孤立波和初始脉冲产生的孤立波的情况。
关键词: 孤立波, 正则长波方程, 守恒差分格式
Abstract: In this paper, We consider solitary waves induced by boundary pulses for regularized Long-wave equation. A conservative difference scheme is presented for the equation. Using the scheme, solitary waves induced by several boundary pulses are computed numerically. We explore the relationship between the amplitudes and numbers of the solitons produced and the boundary pulses, and compare solitons induced by the boundary pulse with ones produced ny initial pulses.
Key words: solitary wave, regular long-wave equation, a conservative difference scheme
