Abstract： Using the theory developed in , certain questions of transport process in strong magnetic field are discussed. In the first place, we show that for this type of transport process one must consider the boundary condition explicitly. For transverse conductivity, it is not necessary to solve the kinetic equation of the Boltzmann type when the boundary condition is treated correctly, and Titeica's picture is shown to be correct in general order of perturbation expansion. Secondly, the solution of the case of external electric field's ω≠0 and its transition to the classical case are discussed. We show that under the same condition ωHτ>1, E0τ? 1, the quantum solution is different from that of the classical case. Finally, in an appendix, the question of eliminated divergence produced by the integral of state density is discussed. We indicate that in the realizable case a term of magnitude (εc/kT)° is as important as that of -ln (εc/kT). This correction makes the theoretical value of ρT/ρL consistent with the experimental data.
