研究具两个非线性项的广义对称正则长波方程孤波解的轨道稳定性.利用方程的两个精确孤波解,推出了判别它们轨道稳定的显式表达式.进一步利用分析方法,给出了较为容易判别这两个孤波解轨道稳定的若干充分条件.
The orbital stability of solitary wave solutions of the generalized symmetric regularized-long-wave equations with two nonlinear items was studied.By using the two precise solitary wave solutions of the given equations,the explicit expression to determine their orbital stability was odtained.Furthermore,several sufficient conditions for the orbital stability of the two solitary wave solutions were provided by corresponding analysis.
