In this paper, a theoretical investigation of nonlinear electron acoustic waves in plasmas containing degenerate electrons at finite temperature, non-degenerate cold electrons and stationary ions has been carried out. We have considered various effects and by employing the standard reductive perturbation technique (RPT), the KdV-Burger equation describing the shock fronts has been studied. The absence of viscous term results in the transformation of KDV-B to KdV equation. The shock fronts have been studied with variations in different plasma parameters. Analytical derivation and numerical simulations have been carried out. The results are important in explaining many phenomena in the inner magnetosphere.

致密内磁层有限温度等离子体中的电子声孤立结构和激波

本文对包含有限温度简并电子、非简并冷电子和静止离子的等离子体中的非线性电子声波进行了理论研究。我们已经考虑了各种影响，并通过采用标准的还原扰动技术 (RPT)，研究了描述激波前沿的 KdV-Burger 方程。粘性项的缺失导致 KDV-B 转换为 KdV 方程。已经研究了不同等离子体参数变化的激波前沿。已经进行了分析推导和数值模拟。这些结果对于解释内磁层中的许多现象很重要。
