The angle (in radians) between the direction of propagation and the direction perpendicular to the magnetic field must be greater than about the square root of the mass ratio, :$\backslash sqrt\}$, in order that the electrons can move along the field lines from crest to trough to satisfy the Boltzmann relation. The dispersion relation is :$\backslash omega^2=\backslash Omega\_c^2+k^2v\_s^2$, where Ωc is the ion cyclotron frequency and ''v''s is the ion sound speed. This relation is the result of restoring forces due to the Lorentz force (see Upper hybrid oscillation for more details), the electrostatic force (the ''T''e term in ''v''s), and the ion pressure (the ''T''i term in ''v''s). == See also == * Waves in plasmas * Ion acoustic wave * Upper hybrid oscillation * Lower hybrid oscillation 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Electrostatic ion cyclotron wave」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
