Project Summary ATM-9318493, Ching-Sheng Wu This proposal will study the basic theory of the plasma emission process as well as its applications. The issues to be addressed include: (1) the effect of velocity dispersion of the beam electrons, (2) finite spectra of backscattered Langmuir waves and low frequency turbulence, (3) effect of quasilinear relaxation of the beam instability on the emission process, (4) nonlinear effects on mode coupling, (5) application of the theory to emissions associated with the bow shock, and (6) discussion of type II and type III radio bursts.

项目摘要：ATM-9318493，吴庆生本课题将研究等离子体发射过程的基本理论及其应用。要解决的问题包括：(1)束流电子速度色散的影响，(2)后向散射朗缪尔波和低频湍流的有限谱，(3)束流不稳定性的拟线性松弛对发射过程的影响，(4)模式耦合的非线性影响，(5)该理论在与弓激波相关的发射中的应用，以及(6)II型和III型射电暴的讨论。
