  In this talk, several new solutions of (2 + 1)-dimensional KadomtsevPetviashvili(KP), Kaup-Kuperschmidt(KK) and Sawada-Kotera(SK) equations are given from non-zero seeds by using gauge transformations.For each of the preceding equations, a Galilean type transformation between these solutions u2 and the previously known so lutions u2 generated from zero seed is given.We present several explicit formulas of the single-soliton solutions for u2 and u2, and further point out the two main differences of them under the same value of parameters, i.e., height and location of peak line, which are demonstrated visibly in three figures.
