推导了描述非均匀磁化等离子体中与低频电磁涨落相关的随机粒子输运的相对论反弹平均拟线性扩散方程。根据与保持第一绝热不变量的低频涨落相关的漂移-反弹共振贡献，显式计算轴对称磁几何中磁囚禁粒子分布的相对论拟线性扩散系数的表达式。
A relativistic bounce-averaged quasilinear diffusion equation is derived to describe stochastic particle transport associated with low-frequency electromagnetic fluctuations in a nonuniform magnetized plasma. Expressions for the relativistic quasilinear diffusion coefficients are calculated explicitly for magnetically-trapped particle distributions in axisymmetric magnetic geometry in terms of drift-bounce resonant contributions associated with low-frequency fluctuations which conserve the first adiabatic invariant.
