• 中文摘要： 由離子迴旋吸收能量來使電漿溫度提高的方法，可利用霍克蒲朗克方程式加上粒子及波作用之項來分析。結果顯示在重氫電漿中使用氦離子 (方程式無法摘錄) 其吸收電波能量的效率較使用氫離子 (方程式無法摘錄) 來得好。這同時也符合實驗的結果。詳細的粒子分佈函數變化將在這篇論文中討論。
• 英文摘要： Plasma heating by ion cyclotron absorption is studied numerically by solving the Fokker-Planckequation in which the quasi-linear diffusion term for cyclotron absorption is added to the Coulomb colli-sion terms The cyclotron absorption of minority ions in a two-ion species tokamak plasma is the mainsubject of this study. In a numerical analysis for (方程式無法摘錄) -deuterium and hydrogen-deuterium plasmas,the results show that plasma heating efficiency is better with a (方程式無法摘錄) minority than with a hydrogenminority, which qualitatively agrees with the experimental results performed in a small experimental toka-mak. The details of the particle velocity evolution in plasmas during the heating process are also obtained,leading to further knowledge of particle distribution functions.
