摘      要：Under investigation in this paper is a generalized(3+1)-dimensional Kadomtsev-Petviashvili equation in fluid dynamics and plasma *** and one-periodic-wave solutions are obtained via the Hirota bilinear method and Hirota-Riemann *** and velocity of the one soliton are *** are presented to discuss the solitons and one-periodic waves:the coefficients in the equation can determine the velocity components of the one soliton,but cannot alter the soliton magnitude;the interaction between the two solitons is elastic;the coefficients in the equation can influence the periods and velocities of the periodic *** between the one-soliton solution and one-periodic wave solution is investigated.
