In this paper, the improved tanh function method in [F.D. Xie, Y. Zhang, Z.S. Lu, Chaos, Solitons & Fractals 24 (2005) 257] is further improved by constructing new ansatz solution of the considered equation. As its application, the (3+1)-dimensional Kadomstev-Petviashvili equation is considered and abundant new exact non-travelling wave solutions are obtained. (c) 2006 Elsevier Inc. All rights reserved.
