A method to evaluate the transport coefficients of charged particles under an electric field is developed. Two velocity-distribution functions p,.(r.) and p.(r') are in-troduced in addition to the usual velocity-distribution function f(v). Here, y,(v.)clv.and z7t.(v')clv are the probabilities of a charged particle starting a new flight with a velocity in the range v., dv., and making a collision at a velocity in the range v', dv', respectively. The velocity-dispersion functions through flight, H(v', v.), and throughscattering, S(v?, v') are used to determine '/'s(Z'o)= Since H(v', v.) includes the full information on the flight of charged particles, the transport coefficients defined in realspace have to be expressed directly by y,(v.). The velocity-distribution function f(v)and the transport coefficients defined in velocity space are also expressed by y.(v.).This method is simple but is applicable to anisotropic systems.
