用tanh方法求出了(3+1)维Kadomtsev-petviashvili(KP)方程和Higher-order Kdv-like方程的行波解.同时和其它方法相比较,展示了tanh方法求解非线性偏微分方程时的简洁性、实用性.

Established traveling wave solutions of the （ 3＋ 1 ）dimensional Kadomtsev-petviashvili （ KP ）equation and Higher-order Kdv-like equation using the tanh method. At the same time, shown that the tanh method＇s simplicity and practicality rather than other methods when constructing traveling wave solutions of the nonlinear partial differential equations.
