摘要：

We study a stationary kinetic equation describing the electron component of nonequilibrium plasma in crossed electric and magnetic fields. The collision integral is taken in the so-called relaxation (BGK) approximation. It is assumed that the plasma parameters vary only along the electric field. Using the Laplace method, asymptotic formulas for the moments of the distribution function including components of the stress tensor and heat flux vector are obtained with a qualified estimate of the remainder.
