摘　　要：基于有限拉莫半径磁流体理论(Finite Larmor radius magnetohydrodynamic)模型,采用WKB(Wentzel、Kramers和Brillouin)的多重尺度分析方法详细推导了一组用于研究托卡马克等离子体中高n电阻性气球模的本征方程。在忽略了回旋粘滞效应和电阻效应之后该方程可以回到传统理想气球模方程。文章中的气球模本征方程可用于研究带耗散性质的电阻率与无耗散的回旋粘滞性的对气球模的竞争影响。In this paper, the effect of finite Larmor radius （FLR） on the high resistive ballooning modes was studied on the basis of FLR magnetohydrodynamic （FLR-MHD） theory. A set of linear FLR resistive ballooning mode equations were derived by using WKB multi-scale analysis method de- veloped by Wentzel, Kramer and Brillouin, which were reduced to the ideal ballooning mode equa- tion when the FLR effect and resistive effect were neglected. The results indicate that the derived ballooning mode equations are applicable in analysing the competitive effects of dissipative resistivity and non-dissipative gyroviscosity on the ballooning modes.
