A dispersion relation has been derived which shows the combined stabilizing effects of convective damping (outgoing boundary condition), average curvature and finite Larmor radius (FLR) on ballooning modes. It has been found that, in contrast to the MHD case, the convective damping influences the stability threshold when FLR effects are included. The highest allowed shear as a function of mode number for free passage to the second stability region has been calculated analytically.
対流減衰(外向き境界条件)、平均曲率、および有限ラーマー半径(FLR)がバルーニングモードに及ぼす複合的な安定化効果を示す分散関係が導出された。MHDの場合とは対照的に、FLR効果を含めると対流減衰が安定性閾値に影響することが見出された。第二安定領域への自由通過のための許容最大シアが、モード数の関数として解析的に計算された。
