论文摘要
对一对血浆中小振幅固定型非线性孤立波的传播进行了研究，通过众所周知的Korteweg de Vries（KDV）（MKDV）方程进行了还原性扰动技术，我们倾向于得出非线性解决方案的确切形式，并研究其特征。考虑到巨大的带电背景物种，两种不同的对离子物种被认为是相反的极性和相同的质量，鉴于对离子环境中感兴趣的频率尺度，这被认为是固定的，第三种被认为是背景缺陷（例如带电灰尘）成分。另一方面，如果一个人忽略了电子正电子歼灭，则该模型共同适用于电子正电子离子（EPI）等离子体。进行参数分析，涉及灰尘血浆组成（背景数密度），物种温度和背景物种的影响。可以看出，对于KDV和MKDV方程，可以观察到可区分的孤立轮廓。结果是在配对离子（富勒烯）实验中的连接，另外可能在天体物理环境中，例如在脉冲星。
The propagation of small amplitude stationary profile nonlinear solitary waves in a pair plasma is investigated employing the reductive perturbation technique via well-known Korteweg de Vries (KdV) and modified KdV (mKdV) equations, we tend to derive the exact form of nonlinear solutions, and study their characteristics. Two distinct pair ion species are considered of opposite polarity and same mass, additionally to a massive charged background species, that is assumed to be stationary, given the frequency scale of interest within the pair ion context, the third species is thought of as a background defect (e.g. charged dust) component. On the opposite hand, the model conjointly applies formally to electron positron ion (epi) plasmas, if one neglects electron positron annihilation. A parametric analysis is carried out, as regards the impact of the dusty plasma composition (background number density), species temperature(s) and background species. It is seen that distinguishable solitary profiles are observed for KdV and mKdV equations. The results are of connection in pair ion (fullerene) experiments and additionally potentially in astrophysical environments, e.g. in pulsars.
