高ポロイダルモード数でイオンラーマ半径より小さい幅の磁気島(微視的磁気島)を解析的に研究した。微視的磁気島の形状関数と回転周波数を二流体電磁流体力学に基づき求めた。微視的磁気島は二つの形状関数により表せる。一つは電場と摂動プラズマ密度を表し、もう一つは摂動電子温度を表す。微視的磁気島の回転周波数に関する問題点について議論した。

Analytical treatment of magnetic islands with high poloidal mode numbers and widths smaller than ion Larmor radius (microislands) is presented. The profile functions and rotation frequencies of microislands are investigated with the two-fluid magnetohydrodynamics. The microislands are described in terms of two profile functions, one of which characterizes the electric field and perturbed plasma density, and second the perturbed electron temperature. The problem of rotation frequencies of microislands is discussed.
