| 摘 要： | 快波加热算法，一般都是假定托卡马克中粒子为麦克斯韦分布.其实由于准线性扩散效应，共振粒子的平行温度与垂直温度不相等，这样必然产生一定的计算误差.针对这种情况，本文引入Fokker-Planck方程，采用叠代算法较好地解决了这一问题.

| Abstract: | The standard normal distribution for particles in tokamak geometry is usually assumed in fast wave heating.In fact,due to the quasi-linear diffusion effect,the parallel and vertical temperatures of the resonant particles are not equal to each other,so,this will bring some error.For this case,the Fokker-Planck equation is introduced in this paper,and iteration algorithm is adopted to solve the problem well. |
