对二维离子-声波系统的非线性演化进行了解析和数值研究。在长波长和小而有限的振幅近似下，得到了描述二维空间中三个孤子的共振相互作用的解。数值解揭示了孤子共振在二维离子声波非线性发展中的重要性。
Nonlinear evolutions of a two-dimensional ion-acoustic wave system are studied analytically and numerically. The solution describing the resonant interaction of three solitons in two-dimensional space is obtained under the approximation of long wavelength and small but finite amplitude. Numerical solutions reveal an importance of soliton resonances in nonlinear developments of two-dimensional ion-acoustic waves.
