利用Fokker-Planck积分近似和Boltzmann积分近似，计算了沿环境磁场漂移速度的双麦克斯韦等离子体中的碰撞动量和能量输运。由这两种方法得到的输运系数与前导阶数相同(与库仑对数成正比)，并以包含广义双超几何函数的封闭形式给出。
Collisional momentum and energy transport in bi-Maxwellian plasmas with a drift velocity along the ambient magnetic field are calculated from both the Fokker–Planck and Boltzmann integral approximations. The transport coefficients obtained from the two approaches are identical to the leading order (proportional to the Coulomb logarithm) and are presented here in a closed form involving generalized double hypergeometric functions.
