将量子流体力学模型应用于量子等离子体中的二维离子声波。利用二维量子流体力学模型，通过约化微扰方法得到了变形的Kortewegde弗里斯（dKdV）方程.利用辅助常方程的解，给出了一种构造非线性量子dKdV方程精确解的推广的直接代数方法。目前的结果描述了这种波的产生和演化，它们的相互作用，以及它们的稳定性。(C)2014 AIP Publishing LLC.
The quantum hydrodynamic model is applied to two-dimensional ion-acoustic waves in quantum plasmas. The two-dimensional quantum hydrodynamic model is used to obtain a deformed Kortewegde Vries (dKdV) equation by reductive perturbation method. By using the solution of auxiliary ordinary equations, a extended direct algebraic method is described to construct the exact solutions for nonlinear quantum dKdV equation. The present results are describing the generation and evolution of such waves, their interactions, and their stability. (C) 2014 AIP Publishing LLC.
