On the basis of Vlasov-Kinetic model and using Maxwell-Juttner distribution function, dispersion relation of electrostatic wave in a collisionless homogeneous relativistic electron plasma is derived. The analysis of the oscillation spectra is carried out in a weak magnetic field limit $\left|\omega -{{kv}}_{{th}}\right|$ ≥ Ω. Approximate analytic expression for the weakly damped mode is obtained in the subluminal limiting range. It is shown that the relativistic weakly damped mode can be estimated analytically in the range where the wave phase velocity v φ becomes greater than relativistic thermal velocity of the electron but less than speed of light. Results in the non-relativistic and the ultrarelativistic cases are also discussed.

弱磁化相对论电子等离子体中静电上混合波和线性Landau阻尼的频谱

在Vlasov-Kinetic模型的基础上,利用Maxwell-Juttner分布函数,推导了无碰撞均质相对论电子等离子体中静电波的色散关系。在≥Ω的弱磁场极限下进行振荡频谱分析$ \ left | \ omega-{{kv}} _ {{th}} \ right | $。在腔内极限范围内获得了弱阻尼模式的近似解析表达式。结果表明,相对论弱阻尼模式可以通过分析在所述波相速度的范围来估计v φ变得比光速大于电子的相对论热速度,但以下。还讨论了非相对论和超相对论情况下的结果。
