Effects of anisotropic thermal transport on the linear stability of the resistive plasma resistive wall mode (RPRWM) are investigated by the magnetohydrodynamic-kinetic hybrid code MARS-K [Liu et al., Phys. Plasmas 15, 112503 (2008)], including the kinetic contribution from energetic particles (EPs). It is found that thermal transport can further stabilize the RPRWM in the presence of drift kinetic contributions from EPs. This is different from the fluid model, which always predicts destabilization of the mode by thermal transport. Furthermore, the thermal transport effect is found to amplify the role played by an adiabatic term, associated with the radial distribution of EPs' birth energy, in modifying the mode stability as well as the mode eigenfunction. The shape of the equilibrium profiles of EPs, in particular that of the temperature, is also found to strongly affect the mode stabilization. This profile effect is more pronounced in the absence of thermal transport. MARS-K computations show that the stabilizing effect by thermal transport is more likely to occur at slower plasma rotation and lower EP energy.

各向异性热传输和高能粒子对电阻等离子体电阻壁模式稳定性的环形建模

各向异性热传输对电阻等离子体电阻壁模式 (RPRWM) 线性稳定性的影响通过磁流体动力学混合代码 MARS-K [Liu et al., Phys. Plasmas 15, 112503 (2008)]，包括高能粒子 (EP) 的动力学贡献。发现在存在来自 EP 的漂移动力学贡献的情况下，热传输可以进一步稳定 RPRWM。这与流体模型不同，流体模型总是通过热传输预测模式的不稳定。此外，发现热传输效应放大了与 EP 出生能量的径向分布相关的绝热项在修改模式稳定性和模式本征函数中的作用。EPs 的平衡曲线的形状，特别是温度的曲线，还发现强烈影响模式稳定性。在没有热传输的情况下，这种剖面效应更为明显。MARS-K 计算表明，热传输的稳定效应更可能发生在较慢的等离子体旋转和较低的 EP 能量下。
