要約(英語): We propose a new idea that the energy distribution of electrons flying in gas under an electric field is observed steady only when the flow rate distribution of electrons circulating the loop through a flight and a collision has converged at a steady form. Procedures adopted in the FTI method, determining the steady flow rate distribution Ψsn(ε0) at first by iteratively operating the loop energy dispersion functions and calculating the steady energy distributions Ff(ε) and Fn(ε) from ψsn(ε0) are just the same as the process that proceeds in nature. In this paper, the new idea and the essence of FTI procedures are described first, and the convergence behavior of ψsn(ε0) in the case elastic and excitation collisions occur dependent on the collision frequencies proportional to the three powers of electron energy are investigated referring the newly defined convergence energy. Obtained transport quantities are discussed from the fundamental view point. The erratum reported in a previous paper is acknowledged with apology.
