摘　　要：研究了KP方程,通过变量变换得到双线性方程.利用符号计算软件maple18,得到了KP方程的可控制中心的怪波,怪波解中含有两个自由参数a和b,选择不同的参数a和b可以控制怪波中心,并作出了怪波有趣的3维演化图和密度图.Under investigation in this paper is KP equation. Bilinear equation is obtained via the dependent variable transformation. the rogue waves with a controllable center are reported for KP equation by using symbolic computation software maple18, Which contain two free parameter α and β.By choosing different parameters α and β can control the center of the rogue waves, The dynamic properties of the rogue waves are three dimensional plots sand density plots.

关 键 词：KP方程 怪波 双线性方程
