摘要：

Evolution of three-dimensional axially symmetric nonlinear pulses in weakly dispersive and dissipative media is studied numerically. The master equation is a generalization of the Zabolotskaya-Khokhlov and Kadomtsev-Petviashvili equations with a Kawahara term. We show that the latter plays a significant role in preventing collapse when it may appear according to the three-dimensional Kadomtsev-Petviashvili equation.
