论文摘要
考虑到任意离子电荷状态，电子有限的Larmor半径（FLR）效应和Debye屏蔽效应，可以得出电磁板通用模式的广义线性色散关系。结果，它提供了更准确的预测，并且适用于更广泛的等离子体。我们发现电子FLR效应对电子等离子体的平板通用不稳定性具有弱稳定的效果，而当$λ_d$接近$ρ_i$（$λ_d$ is debye at debye and debye and deboe $ρ_i$）时，debye屏蔽会强烈稳定这种不稳定性。特别是，我们检查了电子峰值对等离子体中这种不稳定性的稳定性标准，并发现只要对等离子数密度超过临界值$ n_c = b^2/（8πm_ec^2），稳定性在最简单的等离子系统中持续存在。
A generalized linear dispersion relation of electromagnetic slab universal modes is derived, taking into account arbitrary ion charge state, electron finite Larmor radius (FLR) effects, and Debye shielding effects. As a consequence, it provides more accurate predictions and is applicable to a wider range of plasmas. We find that electron FLR effects have a weakly stabilizing effect on the slab universal instability in electron-ion plasma, while Debye shielding strongly stabilizes this instability when $λ_D$ approaches $ρ_i$ ($λ_D$ is the Debye length and $ρ_i$ is the ion gyro-radius). In particular, we examine the stability criterion for this instability in electron-positron pair plasmas, and find that the instability persists in this simplest plasma system as long as the pair plasma number density exceeds the critical value $n_c=B^2/(8πm_e c^2)$.
