论文摘要
在理论上，在具有PowerLaw DSD的无与伦比的无均匀的无凝固性灰尘等离子体中研究了尘埃密度不均匀性和灰尘尺寸分布（DSD）对线性灰尘声（DA）波传播的影响。两种不同类型的波模式，即。在这种不均匀培养基中发现缓慢而快速的模式可以传播。结果表明，DA波的线性色散特性基本上受DSD和密度不均匀性的影响。同样，发现相速度随着灰尘密度的增加而增加。
The impacts of dust density inhomogeneity and dust size distribution (DSD) on linear dust acoustic (DA) wave propagation have been investigated theoretically in an inhomogeneous unmagnetized dusty plasma having powerlaw DSD. Two different types of wave modes, viz. slow and fast mode, are found to propagate in this inhomogeneous medium. It is shown that the linear dispersion characteristics of the DA waves are substantially affected by the DSD and density inhomogeneity. Also, it is found that the phase velocity increases with increasing dust density.
