In this article, a new version of extended F-expansion method is suggested. A multiple Jacobi elliptic functions are presented in the solution function. We achieve analytical solutions of the (1 + 1)-dimensional dispersive long wave (DLW) equation and (2 + 1)-dimensional Kadomtsev–Petviashvili (KP) equation using the new version of extended F-expansion method. Then, the single and the combined non-degenerative Jacobi elliptic function solutions and their degenerate solutions to the above-mentioned class of nonlinear evolution equations are obtained.

新型扩展F展开法的非线性微分方程的多重孤子解

在本文中，建议使用新版本的扩展F展开方法。解函数中存在多个Jacobi椭圆函数。我们使用新版本的扩展F展开方法获得了（1 +1）维色散长波（DLW）方程和（2 +1）维Kadomtsev–Petviashvili（KP）方程的解析解。然后，针对上述一类非线性发展方程，获得了单个和组合的非退化Jacobi椭圆函数解及其退化解。
