电子束驱动的回旋激射不稳定性进一步的数值研究

鉴于近来发现的弱相对论性电子束驱动的回旋激射(maser)不稳定性在太阳射电发射中的重 要应用，在Chen等的理论模型的基础上，对回旋激射不稳定性主要特征在更广泛的参数范围 内进行了进一步的深入研究，丰富了此类等离子体不稳定性的基本内容，而且预期在天体射 电发射机理的研究中也将得到更广泛的应用. 关键词： 回旋激射不稳定性 弱相对论性电子束 增长率

Further numerical study of a maser instability driven by an electron beam

Thorough numerical studies of the characters of maser-instability driven by a beam of weak relativistic electrons are performed on the basis of the theoretical model of Chen et al due to its important application in the solar radio emission. It enriches the fundamental content of the plasma instabilities. And it is expected to be applicable widely in the study of solar and celestial emission mechanism.
