摘要
用动力系统分支理论和数值模拟方法研究3阶KP-BBM方程的扭波,给出了扭波的存在条件,得到了扭波解.从数值模拟的结果看,和其理论分析所得到的结果是相一致的.
The bifurcation theory of dynamical systems and numerical simulation method are employed to investigate the kink waves of a nonlinear cubic KP-BBM equation.The parameter conditions that the kink waves appear are found,and their solutions are obtained.The numerical simulation and qualitative results are identical.
