A correlation is explored between the presence of energetic particle modes (EPM) and long-period sawtooth oscillations in tokamak plasmas heated by rf waves. The eventual crash of these sawteeth is explained in terms of the loss of the stabilizing fast particles due to the EPM. The absence of long-period sawteeth in high q(a) discharges is explained in terms of ion loss due to toroidal Alfven eigenmodes.
研究了托卡马克等离子体中由射频波加热时高能粒子模（EPM）的存在与长周期锯齿振荡之间的相关性。这些锯齿的最终崩溃是根据由于EPM导致的稳定快粒子损失来解释的。高q(a)放电中长周期锯齿的缺失是根据环形阿尔文本征模导致的离子损失来解释的。
