四流体模型与托卡马克等离子体中的扰动粒子流

EQUATION FOR QUADRUPLE FLUIDS AND PERTURBEDPARTICLE FLOWS IN A TOKAMAK PLASMA

基于俘获粒子极向运动的约束条件，提出了一个简单而有效地描述俘获粒子运动及其对某些不稳定性的影响的四流体模型。作为该模型的应用，推导了各种扰动粒子流和扰动条件下的新经典电导率及包括离子惯性效应的更普遍的自举电流表示式，并对径向局域的低极向模数的一类扰动，导出了包含俘获粒子效应的本征模方程。

おased upon the constraint condition on the poloidal motion of trapped particles, a socalled quadruple fluids model is presented, with which the motion of trapped particles and its influence on some instabilities can be treated simply and effectively. As an application of the model, various perturbed particle flows, the neoclassical conductivity under perturbation and more universal expression for the bootstrap current with the ion inertia taken into account are derived. As a step further, the eigenmode equations including trapped particle effects are obtained for the perturbations which have low poloidal mode numbers and are localized radially.
