论文摘要
在未吸收的灰尘血浆中尘埃声孤独波（DASW）的非线性传播，该血浆由带负电荷的灰尘液体玻尔兹曼分布式电子，具有两个不同的温度螺栓雄性分布离子，并研究了两个不同的温度。通过采用对小但有限振幅有效的还原扰动技术，korteweg de vries（K-DV）方程已得出。我们的结果表明，DASW的主要量（例如振幅和宽度）受两个不同温度电子（以及离子）温度比和两个离子的数量密度的影响。结果表明，在这种情况下，正势和负电位DASW都出现。
The nonlinear propagation of dust acoustic solitary waves (DASWs) in an unmagnetized dusty plasma consisting of negatively charged dust fluid Boltzmann distributed electrons with two different temperatures Boltzmann distributed ions with two distinct temperatures are investigated. By employing the reductive perturbation technique that is valid for a small but finite amplitude limit the Korteweg de Vries (K-dV) equation have been derived. Our results reveal that the main quantities of DASWs (such as amplitude and width) are affected by two different temperatures electrons (as well as ions) temperature ratios and the number densities of two species of ions. It is shown that both positive and negative potential DASWs occur in this case.
