| 中文摘要: |
| 从一般形式下的Fokker—Planck方程出发，考虑在电子回旋波和低混杂波驱动等离子体电流和加热情况下高速运动粒子的相对论效应，推导了在动量空间下的碰撞通量、电场感应通量、波感应通量等表达式，得到在电子回旋波和低混杂波加入下可直接用于计算机进行求解的Fokker—Planck方程的具体形式，为进一步数值求解Fokker—Planck方程，研究电子回旋波和低混杂波电流驱动和加热提供了条件。 |
| 英文摘要: |
| Based on the normal form of Fokker-Planck equation,the expressions of collision flux,electric field flux and wave induced flux in the momentum coordinates are deduced in consideration of the relativistic effect of high velocity particles for the case of electron cyclotron wave and lower hybrid wave current drive and heating.The form of Fokker-Planck equation in this case can be solved by using numerical method with the computer.The result will contribute the further numerical solving of Fokker-Planck equation in order to study the electron cyclotron wave and lower hybrid wave to drive current and heat plasma. |
