标题： Drift wave turbulence in the presence of a dust density gradient

摘要： 我们介绍了在存在不动尘埃粒子的非均匀碰撞等离子体中，静电漂移波的湍流特性，该等离子体由磁化电子和离子组成。 为此，我们推导了一对非线性准二维方程，展示了与碰撞漂移波相关的广义离子涡度和密度涨落之间的耦合。 数值研究了尘埃密度梯度对初始漂移不稳定性及完全发展的湍流的影响。 显示英文摘要

摘要： We present turbulent properties of electrostatic drift waves in a nonuniform collisional plasma composed of magnetised electrons and ions in the presence of immobile dust particles. For this purpose, we derive a pair of nonlinear quasi-two-dimensional equations exhibiting the coupling between the generalized ion vorticity and density fluctuations associated with collisional drift waves. The effect of a dust density gradient on the initial drift instability and fully developed turbulence is examined numerically.
