摘要
本文从弱湍动等离子体理论出发 ,由Vlasov方程导出了Maser效应作用机制下共振波的演化规律 ;并且讨论了尘埃等离子体电子束入射情况下 ,共振Langmuir波的增长率。研究结果表明 ,Maser效应比其它不稳定性 (如本文中论及的束流不稳定性等 )能更好的解释空间中的反常Langmuir辐射现象。
Starting from the theory of weakly turbulent plasma, we have derived from the Vlasov equation the evolution of maser-generated resonance waves. We discuss the growth rate of the Langmuir wave in the case of electron beam injection. It is pointed out that the maser effect can better explain the anomalous Langmuir radiation in space than the other plasma instabilities considered in the paper.
