本文从解析和数值计算两种途径仔细研究了磁场非均匀性漂移共振的动力论效应对于漂移迴旋损失锥不稳定性(DCLC)的影响。发现在高β等离子体中,磁场非均匀效应是非常重要的,磁漂移共振对于负能的模起耗散作用,从而使原有的DCLC不稳定性加强,而且不稳定性的参数区域大大扩展了。有限β值效应并没有象流体近似理论所预言的那样使DCLC模稳定。The kinetic effects of magnetic drift resonance on the drift cyclotron loss cone instability (DCLC) are studied in detail both analytically and numerically. It is found that the effects of inhomogeneous magnetic field in high β plasmas are important, the kinetic resonance act as a dissipative effect, which can enhance the instability and broaden the unstable region of negative energy DCLC mode. Finite β effects do not play the stabilization role predicted by the theories under the fluid approximation.
