| 摘 要： | 本文考虑了波驱动通量对磁场位形以及电子密度和温度的空间分布的依赖,应用伴随关系,计算了低混杂波驱动的等离子体电导率的空间分布。结果表明,注入功率谱对电导率空间分布的影响相当敏感,等离子体环外侧的电导率略高于内侧的电导率。但是不论在外侧或内侧,随着离子电荷数增大,波驱动的等离子体电导率降低,而它与斯必泽-亥姆电导率之比却增大。

| Abstract: | Considering the dependence of wave driving flux upon magnetic configuration, electron density profile and electron temperature profile, we have found the conductivity profile in LHW driven plasma by using the adjoint method. The calculated results show that the conductivity is quite sensitive to the launched power spectrum. The plasma conductivity at the outer side of the torus is slightly higher than that at the inner side. At both sides as the ion charge number is increased, the conductivity in LHW driven plasma decreases, but the ratio of this conductivity and the Spitzer-Harm conductivity increases. |
